Telco Customer Churn

Context

Predict behavior to retain customers. You can analyze all relevant customer data and develop focused customer retention programs.

Content

Each row represents a customer, each column contains customer’s attributes described on the column Meta-data.

The data set includes information about:

• Customers who left within the last month – the column is called Churn
• Services that each customer has signed up for – phone, multiple lines, internet, online security, online backup, device protection, tech support, and streaming TV and movies
• Customer account information – how long they’ve been a customer, contract, payment method, paperless billing, monthly charges, and total charges
• Demographic info about customers – gender, age range, and if they have partners and dependents

Predicting on Churn with Binary Classification

As you can see as soon as we uploaded our dataset and selected what column we wanted to predict on, the experiment automatically gave us the best prediction type to use on the data, in this case Binary Classification and is optimized for accuracy and runtime

Progress Map of various Pipelines

Here we can see various amounts of pipelines, each one using a different algorithm, at the bottom we see a comparison of the pipelines and we can see that they choose the most optimal one for our task

Pipeline Comparison

Here we can see that Pipeline 4 has been chosen to be the best measured on accuracy, lets take a look inside the pipeline

Pipeline Analysis I

Here we see the basic information of our Pipeline including the algorithm is used: Random Forest Classifier, the number of features: 34, and number of evaluation instances: 705.

Pipeline Analysis II

Here we see the Feature Summary, each feature with its respective feature importance percentage.

Evaluation Metrics

Here we can see the Evaluation Metrics such as ROC Curve, Cross Validation Score, Precision, F1 Score, etc...

Confusion Matrix
