Understanding the Dataset
Let’s higher perceive our dataset by analyzing its construction and checking for lacking values:
df.information()
RangeIndex: 10127 entries, 0 to 10126
Information columns (whole 14 columns):
# Column Non-Null Rely Dtype
--- ------ -------------- -----
0 customer_id 10127 non-null int64

13 avg_utilization_ratio 10127 non-null float64
dtypes: float64(2), int64(9), object(3)
reminiscence utilization: 1.1+ MB
Our dataset accommodates 10,127 buyer data with 14 variables. Luckily, there are not any lacking values, which simplifies our information preparation course of. Let’s perceive what every of those variables represents:
- customer_id: Distinctive identifier for every buyer
- age: Buyer’s age in years
- gender: Buyer’s gender (M/F)
- dependent_count: Variety of dependents (e.g., youngsters)
- education_level: Buyer’s schooling degree
- marital_status: Buyer’s marital standing
- estimated_income: Estimated annual revenue in {dollars}
- months_on_book: How lengthy the client has been with the bank card firm
- total_relationship_count: Variety of occasions the client has contacted the corporate
- months_inactive_12_mon: Variety of months the client did not use their card up to now 12 months
- credit_limit: Bank card restrict in {dollars}
- total_trans_amount: Complete quantity spent on the bank card
- total_trans_count: Complete variety of transactions
- avg_utilization_ratio: Common card utilization ratio (how a lot of their accessible credit score they use)
Earlier than we dive deeper into the evaluation, let’s examine the distribution of our categorical variables:
print(df['marital_status'].value_counts(), finish="nn")
print(df['gender'].value_counts(), finish="nn")
df['education_level'].value_counts()
marital_status
Married 4687
Single 3943
Unknown 749
Divorced 748
Title: rely, dtype: int64
gender
F 5358
M 4769
Title: rely, dtype: int64
education_level
Graduate 3685
Excessive College 2351
Uneducated 1755
Faculty 1192

Doctorate 528
Title: rely, dtype: int64
About half of the shoppers are married, adopted carefully by single clients, with smaller numbers of consumers with unknown marital standing or divorced.
The gender distribution is pretty balanced, with a slight majority of feminine clients (about 53%) in comparison with male clients (about 47%).
The schooling degree variable reveals that the majority clients have a graduate or highschool schooling, adopted by a considerable portion who’re uneducated. Smaller segments have attended school, achieved post-graduate levels, or earned a doctorate. This implies a variety of instructional backgrounds, with a majority concentrated in mid-level instructional attainment.
Exploratory Information Evaluation (EDA)
Now let’s discover the numerical variables in our dataset to grasp their distributions:
df.describe()
This offers us a statistical abstract of our numerical variables, together with counts, means, normal deviations, and quantiles:
customer_id | age | dependent_count | estimated_income | months_on_book | total_relationship_count | months_inactive_12_mon | credit_limit | total_trans_amount | total_trans_count | avg_utilization_ratio | |
---|---|---|---|---|---|---|---|---|---|---|---|

To make it simpler to identify patterns, let’s visualize the distribution of every variable utilizing histograms:
fig, ax = plt.subplots(figsize=(12, 10))
# Eradicating the client's id earlier than plotting the distributions
df.drop('customer_id', axis=1).hist(ax=ax)
plt.tight_layout()
plt.present()

Studying Perception: When working with Jupyter and
matplotlib
, you may see warning messages about a number of subplots. These are usually innocent and simply inform you thatmatplotlib
is dealing with some facets of the plot creation routinely. For a portfolio challenge, you may need to refine your code to eradicate these warnings, however they do not have an effect on the performance or accuracy of your evaluation.
From these histograms, we will observe:
- Age: Pretty usually distributed, concentrated between 40-55 years
- Dependent Rely: Most clients have 0-3 dependents
- Estimated Earnings: Proper-skewed, with most clients having incomes beneath $100,000
- Months on E book: Usually distributed, centered round 36 months
- Complete Relationship Rely: Most clients have 3-5 contacts with the corporate
- Credit score Restrict: Proper-skewed, with most clients having a credit score restrict beneath $10,000
- Transaction Metrics: Each quantity and rely present some proper skew
- Utilization Ratio: Many shoppers have very low utilization (close to 0), with a smaller group having excessive utilization
Subsequent, let’s take a look at correlations between variables to grasp relationships inside our information and visualize them utilizing a heatmap:
correlations = df.drop('customer_id', axis=1).corr(numeric_only=True)
fig, ax = plt.subplots(figsize=(12,8))
sns.heatmap(correlations[(correlations > 0.30) | (correlations < -0.30)],
cmap='Blues', annot=True, ax=ax)
plt.tight_layout()
plt.present()
Studying Perception: When creating correlation heatmaps, filtering to indicate solely stronger correlations (e.g., these above 0.3 or beneath -0.3) could make the visualization rather more readable and aid you concentrate on a very powerful relationships in your information.
The correlation heatmap reveals a number of fascinating relationships:
- Age and Months on E book: Robust optimistic correlation (0.79), suggesting older clients have been with the corporate longer
- Credit score Restrict and Estimated Earnings: Constructive correlation (0.52), which is sensible as greater revenue sometimes qualifies for greater credit score limits
- Transaction Quantity and Rely: Robust optimistic correlation (0.81), which means clients who make extra transactions additionally spend extra total
- Credit score Restrict and Utilization Ratio: Detrimental correlation (-0.48), suggesting clients with greater credit score limits have a tendency to make use of a smaller proportion of their accessible credit score
- Relationship Rely and Transaction Quantity: Detrimental correlation (-0.35), curiously indicating that clients who contact the corporate extra are inclined to spend much less
These relationships shall be precious to contemplate as we interpret our clustering outcomes later.
Characteristic Engineering
Earlier than we will apply Ok-means clustering, we have to remodel our categorical variables into numerical representations. Ok-means operates by calculating distances between factors in a multi-dimensional area, so all options should be numeric.
Let’s deal with every categorical variable appropriately:
1. Gender Transformation
Since gender is binary on this dataset (M/F), we will use a easy mapping:
customers_modif = df.copy()
customers_modif['gender'] = df['gender'].apply(lambda x: 1 if x == 'M' else 0)
customers_modif.head()
Studying Perception: When a categorical variable has solely two classes, you need to use a easy binary encoding (0/1) fairly than one-hot encoding. This reduces the dimensionality of your information and might result in extra interpretable fashions.
2. Training Degree Transformation
Training degree has a pure ordering (uneducated < highschool < school, and many others.), so we will use ordinal encoding:
education_mapping = {'Uneducated': 0, 'Excessive College': 1, 'Faculty': 2,
'Graduate': 3, 'Put up-Graduate': 4, 'Doctorate': 5}
customers_modif['education_level'] = customers_modif['education_level'].map(education_mapping)
customers_modif.head()
3. Marital Standing Transformation
Marital standing would not have a pure ordering, and it has greater than two classes, so we’ll use one-hot encoding:
dummies = pd.get_dummies(customers_modif[['marital_status']])
customers_modif = pd.concat([customers_modif, dummies], axis=1)
customers_modif.drop(['marital_status'], axis=1, inplace=True)
print(customers_modif.information())
customers_modif.head()
RangeIndex: 10127 entries, 0 to 10126
Information columns (whole 17 columns):
# Column Non-Null Rely Dtype
--- ------ -------------- -----
0 customer_id 10127 non-null int64
1 age 10127 non-null int64
2 gender 10127 non-null int64
3 dependent_count 10127 non-null int64
4 education_level 10127 non-null int64
5 estimated_income 10127 non-null int64
6 months_on_book 10127 non-null int64
7 total_relationship_count 10127 non-null int64
8 months_inactive_12_mon 10127 non-null int64
9 credit_limit 10127 non-null float64
10 total_trans_amount 10127 non-null int64
11 total_trans_count 10127 non-null int64
12 avg_utilization_ratio 10127 non-null float64
13 marital_status_Divorced 10127 non-null bool
14 marital_status_Married 10127 non-null bool
15 marital_status_Single 10127 non-null bool
16 marital_status_Unknown 10127 non-null bool
dtypes: bool(4), float64(2), int64(11)
reminiscence utilization: 1.0 MB
Studying Perception: One-hot encoding creates a brand new binary column for every class, which might result in an “implicit weighting” impact if a variable has many classes. That is one thing to pay attention to when decoding clustering outcomes, as it could actually generally trigger the algorithm to prioritize variables with extra classes.
Now our information is absolutely numeric and prepared for scaling and clustering.
Scaling the Information
Ok-means clustering makes use of distance-based calculations, so it is necessary to scale our options to make sure that variables with bigger ranges (like revenue) do not dominate the clustering course of over variables with smaller ranges (like age).
X = customers_modif.drop('customer_id', axis=1)
scaler = StandardScaler()
scaler.match(X)
X_scaled = scaler.remodel(X)
Studying Perception:
StandardScaler
transforms every characteristic to have a imply of 0 and a normal deviation of 1. This places all options on an equal footing, no matter their unique scales. For Ok-means clustering, that is what ensures that every characteristic contributes equally to the space calculations.
Discovering the Optimum Variety of Clusters
One of many challenges with Ok-means clustering is figuring out the optimum variety of clusters. The elbow methodology is a standard method, the place we plot the sum of squared distances (inertia) for various numbers of clusters and search for an “elbow” level the place the speed of lower sharply modifications.
X = pd.DataFrame(X_scaled)
inertias = []
for okay in vary(1, 11):
mannequin = KMeans(n_clusters=okay)
y = mannequin.fit_predict(X)
inertias.append(mannequin.inertia_)
plt.determine(figsize=(12, 8))
plt.plot(vary(1, 11), inertias, marker='o')
plt.xticks(ticks=vary(1, 11), labels=vary(1, 11))
plt.title('Inertia vs Variety of Clusters')
plt.tight_layout()
plt.present()
Studying Perception: The elbow methodology is not all the time crystal clear, and there is typically some judgment concerned in choosing the “proper” variety of clusters. Think about working the clustering a number of occasions with totally different numbers of clusters and evaluating which answer supplies probably the most actionable insights for your corporation context.
In our case, the plot means that round 5-8 clusters could possibly be acceptable, because the lower in inertia begins to degree off on this vary. For this evaluation, we’ll select 8 clusters, because it seems to strike a great stability between element and interpretability.
Constructing the Ok-Means Clustering Mannequin
Now that we have decided the optimum variety of clusters, let’s construct our Ok-means mannequin:
mannequin = KMeans(n_clusters=8)
y = mannequin.fit_predict(X_scaled)
# Including the cluster assignments to our unique dataframe
df['CLUSTER'] = y + 1 # Including 1 to make clusters 1-based as a substitute of 0-based
df.head()
Let’s examine what number of clients we have now in every cluster:
df['CLUSTER'].value_counts()
CLUSTER
5 2015
7 1910
2 1577
1 1320
4 1045
6 794
3 736
8 730
Title: rely, dtype: int64
Our clusters have moderately balanced sizes, with no single cluster dominating the others.
Analyzing the Clusters
Now that we have created our buyer segments, let’s analyze them to grasp what makes every cluster distinctive. We’ll begin by analyzing the typical values of numeric variables for every cluster:
numeric_columns = df.select_dtypes(embrace=np.quantity).drop(['customer_id', 'CLUSTER'], axis=1).columns
fig = plt.determine(figsize=(20, 20))
for i, column in enumerate(numeric_columns):
df_plot = df.groupby('CLUSTER')[column].imply()
ax = fig.add_subplot(5, 2, i+1)
ax.bar(df_plot.index, df_plot, colour=sns.color_palette('Set1'), alpha=0.6)
ax.set_title(f'Common {column.title()} per Cluster', alpha=0.5)
ax.xaxis.grid(False)
plt.tight_layout()
plt.present()
These bar charts assist us perceive how every variable differs throughout clusters. For instance, we will see:
- Estimated Earnings: Clusters 1 and a pair of have considerably greater common incomes
- Credit score Restrict: Equally, Clusters 1 and a pair of have greater credit score limits
- Transaction Metrics: Cluster 6 stands out with a lot greater transaction quantities and counts
Let’s additionally take a look at how the clusters seem in scatter plots of key variables:
fig, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2, 2, figsize=(16, 8))
sns.scatterplot(x='age', y='months_on_book', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax1)
sns.scatterplot(x='estimated_income', y='credit_limit', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax2, legend=False)
sns.scatterplot(x='credit_limit', y='avg_utilization_ratio', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax3)
sns.scatterplot(x='total_trans_count', y='total_trans_amount', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax4, legend=False)
plt.tight_layout()
plt.present()
The scatter plots reveal some fascinating patterns:
- Within the Credit score Restrict vs. Utilization Ratio plot, we will see distinct clusters with totally different behaviors – some have excessive credit score limits however low utilization, whereas others have decrease limits however greater utilization
- The Transaction Rely vs. Quantity plot reveals Cluster 6 as a definite group with excessive transaction exercise
- The Age vs. Months on E book plot reveals the anticipated optimistic correlation, however with some fascinating cluster separations
Lastly, let’s look at the distribution of categorical variables throughout clusters:
cat_columns = df.select_dtypes(embrace=['object'])
fig = plt.determine(figsize=(18, 6))
for i, col in enumerate(cat_columns):
plot_df = pd.crosstab(index=df['CLUSTER'], columns=df[col], values=df[col], aggfunc='measurement', normalize='index')
ax = fig.add_subplot(1, 3, i+1)
plot_df.plot.bar(stacked=True, ax=ax, alpha=0.6)
ax.set_title(f'% {col.title()} per Cluster', alpha=0.5)
ax.set_ylim(0, 1.4)
ax.legend(frameon=False)
ax.xaxis.grid(False)
plt.tight_layout()
plt.present()
These stacked bar charts reveal some robust patterns:
- Gender: Some clusters are closely skewed in direction of one gender (e.g., Clusters 5 and seven are predominantly feminine)
- Marital Standing: Sure clusters are strongly related to particular marital statuses (e.g., Cluster 2 is generally married, Cluster 5 is generally single)
- Training Degree: This reveals extra blended patterns throughout clusters
Studying Perception: The robust affect of marital standing on our clustering outcomes could be partly as a result of one-hot encoding we used, which created 4 separate columns for this variable. In future iterations, you may need to experiment with totally different encoding strategies or scaling to see the way it impacts your outcomes.
Buyer Phase Profiles
Based mostly on our evaluation, we will create profiles for every buyer section, summarized within the desk beneath:
Excessive-Earnings Single Males | • Predominantly male • Principally single |
• Excessive revenue (~$100K) • Excessive credit score restrict |
• Low bank card utilization (10%) | These clients have cash to spend however aren’t utilizing their playing cards a lot. The corporate may provide rewards or incentives particularly tailor-made to single professionals to encourage extra card utilization. | |
Prosperous Household Males | • Predominantly male • Married • Greater variety of dependents (~2.5) |
• Excessive revenue (~$100K) • Excessive credit score restrict |
• Low utilization ratio (15%) | These clients symbolize family-oriented excessive earners. Household-focused rewards applications or partnerships with family-friendly retailers may enhance their card utilization. | |
Divorced Mid-Earnings Clients | • Combined gender • Predominantly divorced |

• Excessive utilization ratio | This section may profit from entry-level monetary schooling and accountable credit score utilization applications. They could even be receptive to credit score restrict enhance provides as their careers progress. | |
Massive Spenders | • 60% male • Mixture of single and married |
• Above-average revenue (~$70K) • Excessive credit score restrict |
• Highest transaction rely and quantity by a big margin | These are the corporate’s most lively clients. Premium rewards applications and unique perks may assist preserve their excessive engagement. | |
Household-Targeted Ladies | • 90% feminine • Married • Highest variety of dependents |
• Low revenue (~$40K) • Low credit score restrict paired with excessive utilization |
• Average transaction patterns | This section may reply nicely to family-oriented promotions and cash-back on on a regular basis purchases like groceries and youngsters’s gadgets. | |
Unknown Marital Standing | • Combined gender • All with unknown marital standing |
• Common throughout most metrics | • No distinct patterns | This section primarily exists attributable to lacking information. The corporate ought to try and replace these data to raised categorize these clients. |
Challenges and Concerns
Our evaluation revealed some fascinating patterns, but in addition highlighted a possible concern with our method. The robust affect of marital standing on our clustering outcomes means that our one-hot encoding of this variable may need given it extra weight than supposed. This “implicit weighting” impact is a standard problem when utilizing one-hot encoding with Ok-means clustering.
For future iterations, we’d contemplate:
- Various Encoding Strategies: Attempt totally different approaches for categorical variables
- Take away Particular Classes: Take a look at if eradicating the “Unknown” marital standing modifications the clustering patterns

13 avg_utilization_ratio 10127 non-null float64
dtypes: float64(2), int64(9), object(3)
reminiscence utilization: 1.1+ MB
Our dataset accommodates 10,127 buyer data with 14 variables. Luckily, there are not any lacking values, which simplifies our information preparation course of. Let’s perceive what every of those variables represents:
- customer_id: Distinctive identifier for every buyer
- age: Buyer’s age in years
- gender: Buyer’s gender (M/F)
- dependent_count: Variety of dependents (e.g., youngsters)
- education_level: Buyer’s schooling degree
- marital_status: Buyer’s marital standing
- estimated_income: Estimated annual revenue in {dollars}
- months_on_book: How lengthy the client has been with the bank card firm
- total_relationship_count: Variety of occasions the client has contacted the corporate
- months_inactive_12_mon: Variety of months the client did not use their card up to now 12 months
- credit_limit: Bank card restrict in {dollars}
- total_trans_amount: Complete quantity spent on the bank card
- total_trans_count: Complete variety of transactions
- avg_utilization_ratio: Common card utilization ratio (how a lot of their accessible credit score they use)
Earlier than we dive deeper into the evaluation, let’s examine the distribution of our categorical variables:
print(df['marital_status'].value_counts(), finish="nn")
print(df['gender'].value_counts(), finish="nn")
df['education_level'].value_counts()
marital_status
Married 4687
Single 3943
Unknown 749
Divorced 748
Title: rely, dtype: int64

Title: rely, dtype: int64
About half of the shoppers are married, adopted carefully by single clients, with smaller numbers of consumers with unknown marital standing or divorced.
The gender distribution is pretty balanced, with a slight majority of feminine clients (about 53%) in comparison with male clients (about 47%).
The schooling degree variable reveals that the majority clients have a graduate or highschool schooling, adopted by a considerable portion who’re uneducated. Smaller segments have attended school, achieved post-graduate levels, or earned a doctorate. This implies a variety of instructional backgrounds, with a majority concentrated in mid-level instructional attainment.
Exploratory Information Evaluation (EDA)
Now let’s discover the numerical variables in our dataset to grasp their distributions:
df.describe()
This offers us a statistical abstract of our numerical variables, together with counts, means, normal deviations, and quantiles:
customer_id | age | dependent_count | estimated_income | months_on_book | total_relationship_count | months_inactive_12_mon | credit_limit | total_trans_amount | total_trans_count | avg_utilization_ratio | |
---|---|---|---|---|---|---|---|---|---|---|---|

To make it simpler to identify patterns, let’s visualize the distribution of every variable utilizing histograms:
fig, ax = plt.subplots(figsize=(12, 10))
# Eradicating the client's id earlier than plotting the distributions
df.drop('customer_id', axis=1).hist(ax=ax)
plt.tight_layout()
plt.present()
Studying Perception: When working with Jupyter and
matplotlib
, you may see warning messages about a number of subplots. These are usually innocent and simply inform you thatmatplotlib
is dealing with some facets of the plot creation routinely. For a portfolio challenge, you may need to refine your code to eradicate these warnings, however they do not have an effect on the performance or accuracy of your evaluation.
From these histograms, we will observe:
- Age: Pretty usually distributed, concentrated between 40-55 years
- Dependent Rely: Most clients have 0-3 dependents
- Estimated Earnings: Proper-skewed, with most clients having incomes beneath $100,000
- Months on E book: Usually distributed, centered round 36 months
- Complete Relationship Rely: Most clients have 3-5 contacts with the corporate
- Credit score Restrict: Proper-skewed, with most clients having a credit score restrict beneath $10,000
- Transaction Metrics: Each quantity and rely present some proper skew
- Utilization Ratio: Many shoppers have very low utilization (close to 0), with a smaller group having excessive utilization
Subsequent, let’s take a look at correlations between variables to grasp relationships inside our information and visualize them utilizing a heatmap:
correlations = df.drop('customer_id', axis=1).corr(numeric_only=True)
fig, ax = plt.subplots(figsize=(12,8))
sns.heatmap(correlations[(correlations > 0.30) | (correlations < -0.30)],
cmap='Blues', annot=True, ax=ax)
plt.tight_layout()
plt.present()
Studying Perception: When creating correlation heatmaps, filtering to indicate solely stronger correlations (e.g., these above 0.3 or beneath -0.3) could make the visualization rather more readable and aid you concentrate on a very powerful relationships in your information.
The correlation heatmap reveals a number of fascinating relationships:
- Age and Months on E book: Robust optimistic correlation (0.79), suggesting older clients have been with the corporate longer
- Credit score Restrict and Estimated Earnings: Constructive correlation (0.52), which is sensible as greater revenue sometimes qualifies for greater credit score limits
- Transaction Quantity and Rely: Robust optimistic correlation (0.81), which means clients who make extra transactions additionally spend extra total
- Credit score Restrict and Utilization Ratio: Detrimental correlation (-0.48), suggesting clients with greater credit score limits have a tendency to make use of a smaller proportion of their accessible credit score
- Relationship Rely and Transaction Quantity: Detrimental correlation (-0.35), curiously indicating that clients who contact the corporate extra are inclined to spend much less
These relationships shall be precious to contemplate as we interpret our clustering outcomes later.
Characteristic Engineering
Earlier than we will apply Ok-means clustering, we have to remodel our categorical variables into numerical representations. Ok-means operates by calculating distances between factors in a multi-dimensional area, so all options should be numeric.
Let’s deal with every categorical variable appropriately:
1. Gender Transformation
Since gender is binary on this dataset (M/F), we will use a easy mapping:
customers_modif = df.copy()
customers_modif['gender'] = df['gender'].apply(lambda x: 1 if x == 'M' else 0)
customers_modif.head()
Studying Perception: When a categorical variable has solely two classes, you need to use a easy binary encoding (0/1) fairly than one-hot encoding. This reduces the dimensionality of your information and might result in extra interpretable fashions.
2. Training Degree Transformation
Training degree has a pure ordering (uneducated < highschool < school, and many others.), so we will use ordinal encoding:
education_mapping = {'Uneducated': 0, 'Excessive College': 1, 'Faculty': 2,
'Graduate': 3, 'Put up-Graduate': 4, 'Doctorate': 5}
customers_modif['education_level'] = customers_modif['education_level'].map(education_mapping)
customers_modif.head()
3. Marital Standing Transformation
Marital standing would not have a pure ordering, and it has greater than two classes, so we’ll use one-hot encoding:
dummies = pd.get_dummies(customers_modif[['marital_status']])
customers_modif = pd.concat([customers_modif, dummies], axis=1)
customers_modif.drop(['marital_status'], axis=1, inplace=True)
print(customers_modif.information())
customers_modif.head()
RangeIndex: 10127 entries, 0 to 10126
Information columns (whole 17 columns):
# Column Non-Null Rely Dtype
--- ------ -------------- -----
0 customer_id 10127 non-null int64
1 age 10127 non-null int64
2 gender 10127 non-null int64
3 dependent_count 10127 non-null int64
4 education_level 10127 non-null int64
5 estimated_income 10127 non-null int64
6 months_on_book 10127 non-null int64
7 total_relationship_count 10127 non-null int64
8 months_inactive_12_mon 10127 non-null int64
9 credit_limit 10127 non-null float64
10 total_trans_amount 10127 non-null int64
11 total_trans_count 10127 non-null int64
12 avg_utilization_ratio 10127 non-null float64
13 marital_status_Divorced 10127 non-null bool
14 marital_status_Married 10127 non-null bool
15 marital_status_Single 10127 non-null bool
16 marital_status_Unknown 10127 non-null bool
dtypes: bool(4), float64(2), int64(11)
reminiscence utilization: 1.0 MB
Studying Perception: One-hot encoding creates a brand new binary column for every class, which might result in an “implicit weighting” impact if a variable has many classes. That is one thing to pay attention to when decoding clustering outcomes, as it could actually generally trigger the algorithm to prioritize variables with extra classes.
Now our information is absolutely numeric and prepared for scaling and clustering.
Scaling the Information
Ok-means clustering makes use of distance-based calculations, so it is necessary to scale our options to make sure that variables with bigger ranges (like revenue) do not dominate the clustering course of over variables with smaller ranges (like age).
X = customers_modif.drop('customer_id', axis=1)
scaler = StandardScaler()
scaler.match(X)
X_scaled = scaler.remodel(X)
Studying Perception:
StandardScaler
transforms every characteristic to have a imply of 0 and a normal deviation of 1. This places all options on an equal footing, no matter their unique scales. For Ok-means clustering, that is what ensures that every characteristic contributes equally to the space calculations.
Discovering the Optimum Variety of Clusters
One of many challenges with Ok-means clustering is figuring out the optimum variety of clusters. The elbow methodology is a standard method, the place we plot the sum of squared distances (inertia) for various numbers of clusters and search for an “elbow” level the place the speed of lower sharply modifications.
X = pd.DataFrame(X_scaled)
inertias = []
for okay in vary(1, 11):
mannequin = KMeans(n_clusters=okay)
y = mannequin.fit_predict(X)
inertias.append(mannequin.inertia_)
plt.determine(figsize=(12, 8))
plt.plot(vary(1, 11), inertias, marker='o')
plt.xticks(ticks=vary(1, 11), labels=vary(1, 11))
plt.title('Inertia vs Variety of Clusters')
plt.tight_layout()
plt.present()
Studying Perception: The elbow methodology is not all the time crystal clear, and there is typically some judgment concerned in choosing the “proper” variety of clusters. Think about working the clustering a number of occasions with totally different numbers of clusters and evaluating which answer supplies probably the most actionable insights for your corporation context.
In our case, the plot means that round 5-8 clusters could possibly be acceptable, because the lower in inertia begins to degree off on this vary. For this evaluation, we’ll select 8 clusters, because it seems to strike a great stability between element and interpretability.
Constructing the Ok-Means Clustering Mannequin
Now that we have decided the optimum variety of clusters, let’s construct our Ok-means mannequin:
mannequin = KMeans(n_clusters=8)
y = mannequin.fit_predict(X_scaled)
# Including the cluster assignments to our unique dataframe
df['CLUSTER'] = y + 1 # Including 1 to make clusters 1-based as a substitute of 0-based
df.head()
Let’s examine what number of clients we have now in every cluster:
df['CLUSTER'].value_counts()
CLUSTER
5 2015
7 1910
2 1577
1 1320
4 1045
6 794
3 736
8 730
Title: rely, dtype: int64
Our clusters have moderately balanced sizes, with no single cluster dominating the others.
Analyzing the Clusters
Now that we have created our buyer segments, let’s analyze them to grasp what makes every cluster distinctive. We’ll begin by analyzing the typical values of numeric variables for every cluster:
numeric_columns = df.select_dtypes(embrace=np.quantity).drop(['customer_id', 'CLUSTER'], axis=1).columns
fig = plt.determine(figsize=(20, 20))
for i, column in enumerate(numeric_columns):
df_plot = df.groupby('CLUSTER')[column].imply()
ax = fig.add_subplot(5, 2, i+1)
ax.bar(df_plot.index, df_plot, colour=sns.color_palette('Set1'), alpha=0.6)
ax.set_title(f'Common {column.title()} per Cluster', alpha=0.5)
ax.xaxis.grid(False)
plt.tight_layout()
plt.present()
These bar charts assist us perceive how every variable differs throughout clusters. For instance, we will see:
- Estimated Earnings: Clusters 1 and a pair of have considerably greater common incomes
- Credit score Restrict: Equally, Clusters 1 and a pair of have greater credit score limits
- Transaction Metrics: Cluster 6 stands out with a lot greater transaction quantities and counts
Let’s additionally take a look at how the clusters seem in scatter plots of key variables:
fig, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2, 2, figsize=(16, 8))
sns.scatterplot(x='age', y='months_on_book', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax1)
sns.scatterplot(x='estimated_income', y='credit_limit', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax2, legend=False)
sns.scatterplot(x='credit_limit', y='avg_utilization_ratio', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax3)
sns.scatterplot(x='total_trans_count', y='total_trans_amount', hue='CLUSTER', information=df, palette='tab10', alpha=0.4, ax=ax4, legend=False)
plt.tight_layout()
plt.present()
The scatter plots reveal some fascinating patterns:
- Within the Credit score Restrict vs. Utilization Ratio plot, we will see distinct clusters with totally different behaviors – some have excessive credit score limits however low utilization, whereas others have decrease limits however greater utilization
- The Transaction Rely vs. Quantity plot reveals Cluster 6 as a definite group with excessive transaction exercise
- The Age vs. Months on E book plot reveals the anticipated optimistic correlation, however with some fascinating cluster separations
Lastly, let’s look at the distribution of categorical variables throughout clusters:
cat_columns = df.select_dtypes(embrace=['object'])
fig = plt.determine(figsize=(18, 6))
for i, col in enumerate(cat_columns):
plot_df = pd.crosstab(index=df['CLUSTER'], columns=df[col], values=df[col], aggfunc='measurement', normalize='index')
ax = fig.add_subplot(1, 3, i+1)
plot_df.plot.bar(stacked=True, ax=ax, alpha=0.6)
ax.set_title(f'% {col.title()} per Cluster', alpha=0.5)
ax.set_ylim(0, 1.4)
ax.legend(frameon=False)
ax.xaxis.grid(False)
plt.tight_layout()
plt.present()
These stacked bar charts reveal some robust patterns:
- Gender: Some clusters are closely skewed in direction of one gender (e.g., Clusters 5 and seven are predominantly feminine)
- Marital Standing: Sure clusters are strongly related to particular marital statuses (e.g., Cluster 2 is generally married, Cluster 5 is generally single)
- Training Degree: This reveals extra blended patterns throughout clusters
Studying Perception: The robust affect of marital standing on our clustering outcomes could be partly as a result of one-hot encoding we used, which created 4 separate columns for this variable. In future iterations, you may need to experiment with totally different encoding strategies or scaling to see the way it impacts your outcomes.
Buyer Phase Profiles
Based mostly on our evaluation, we will create profiles for every buyer section, summarized within the desk beneath:
Excessive-Earnings Single Males | • Predominantly male • Principally single |
• Excessive revenue (~$100K) • Excessive credit score restrict |
• Low bank card utilization (10%) | These clients have cash to spend however aren’t utilizing their playing cards a lot. The corporate may provide rewards or incentives particularly tailor-made to single professionals to encourage extra card utilization. | |
Prosperous Household Males | • Predominantly male • Married • Greater variety of dependents (~2.5) |
• Excessive revenue (~$100K) • Excessive credit score restrict |
• Low utilization ratio (15%) | These clients symbolize family-oriented excessive earners. Household-focused rewards applications or partnerships with family-friendly retailers may enhance their card utilization. | |
Divorced Mid-Earnings Clients | • Combined gender • Predominantly divorced |
• Common revenue and credit score restrict | • Common transaction patterns | This section may reply nicely to monetary planning providers or stability-focused messaging as they navigate post-divorce funds. | |
Older Loyal Clients | • 60% feminine • 70% married • Oldest common age (~60) |
• Decrease credit score restrict • Greater utilization ratio |
• Longest relationship with the corporate • Few dependents |
These loyal clients may admire recognition applications and senior-focused advantages. | |
Younger Single Ladies | • 90% feminine • Predominantly single |
• Lowest common revenue (~$40K) • Low credit score restrict |
• Excessive utilization ratio | This section may profit from entry-level monetary schooling and accountable credit score utilization applications. They could even be receptive to credit score restrict enhance provides as their careers progress. | |
Massive Spenders | • 60% male • Mixture of single and married |
• Above-average revenue (~$70K) • Excessive credit score restrict |
• Highest transaction rely and quantity by a big margin | These are the corporate’s most lively clients. Premium rewards applications and unique perks may assist preserve their excessive engagement. | |
Household-Targeted Ladies | • 90% feminine • Married • Highest variety of dependents |
• Low revenue (~$40K) • Low credit score restrict paired with excessive utilization |
• Average transaction patterns | This section may reply nicely to family-oriented promotions and cash-back on on a regular basis purchases like groceries and youngsters’s gadgets. | |
Unknown Marital Standing | • Combined gender • All with unknown marital standing |
• Common throughout most metrics | • No distinct patterns | This section primarily exists attributable to lacking information. The corporate ought to try and replace these data to raised categorize these clients. |
Challenges and Concerns
Our evaluation revealed some fascinating patterns, but in addition highlighted a possible concern with our method. The robust affect of marital standing on our clustering outcomes means that our one-hot encoding of this variable may need given it extra weight than supposed. This “implicit weighting” impact is a standard problem when utilizing one-hot encoding with Ok-means clustering.
For future iterations, we’d contemplate:
- Various Encoding Strategies: Attempt totally different approaches for categorical variables
- Take away Particular Classes: Take a look at if eradicating the “Unknown” marital standing modifications the clustering patterns
- Totally different Distance Metrics: Experiment with different distance calculations for Ok-means
- Characteristic Choice: Explicitly select which options to incorporate within the clustering
Abstract of Evaluation
On this challenge, we have demonstrated how unsupervised machine studying can be utilized to section clients primarily based on their demographic and behavioral traits. These segments present precious insights {that a} bank card firm can use to develop focused advertising and marketing methods and enhance buyer engagement.
Our evaluation recognized eight distinct buyer segments, every with their very own traits and alternatives for focused advertising and marketing:
- Excessive-income single males
- Prosperous household males
- Divorced mid-income clients
- Older loyal clients
- Younger single girls
- Massive spenders
- Household-focused girls
- Unknown marital standing (potential information concern)
These groupings may also help the corporate tailor their advertising and marketing messages, rewards applications, and product choices to the particular wants and behaviors of every buyer section, doubtlessly resulting in elevated card utilization, buyer satisfaction, and income.
Subsequent Steps
