Telecom Customer Churn Dataset
This dataset comes from an Iranian telecom company, with each row representing a customer over a year period. Along with a churn label, there is information on the customers' activity, such as call failures and subscription length.
import shap
import pandas as pd
import numpy as np
shap.initjs()
customer = pd.read_csv("data/customer_churn.csv")
customer.head()
customer.Churn.value_counts()
X = customer.drop("Churn", axis=1) # Independent variables
y = customer.Churn # Dependent variable
Training a machine learning model
# Split into train and test
from sklearn.model_selection import train_test_split
X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.3, random_state=1)
# Train a machine learning model (example: Random Forest)
from sklearn.ensemble import RandomForestClassifier
clf = RandomForestClassifier()
clf.fit(X_train, y_train)
Model Evaluation
from sklearn.metrics import classification_report
# Make prediction on the testing data
y_pred = clf.predict(X_test)
# Classification Report
print(classification_report(y_pred, y_test))
Explain the model's predictions using SHAP
explainer = shap.Explainer(clf)
shap_values = explainer.shap_values(X_test)
Summarize feature importances
# Summarize feature importances
shap.summary_plot(shap_values, X_test)
Feature importances of Label "0"
shap.summary_plot(shap_values[0], X_test)
shap.summary_plot(shap_values[1], X_test)
