Machine learning use case

Customer churn prediction

Build and compare customer churn classifiers using contract, service, tenure, and billing features.

Experiment design

Setup used for the reference run

This fixed setup makes the comparison understandable and repeatable. It is an example configuration, not an automatic recommendation for every dataset.

DatasetIBM Telco Customer Churn
TargetChurn (Yes/No)
Validation80/20 holdout
Random state42

Input features

19 service, account, billing, and demographic fields

Preprocessing

Coerce TotalCharges to numeric, impute missing values, standardize numeric columns, one-hot encode categories.

Build sequence

Recreate the experiment in AutoTrain

  1. Inspect the dataset.Confirm field types, missing values, class balance, identifiers, and whether each feature exists at prediction time.
  2. Save preprocessing.Apply the documented transformations without fitting them on the holdout rows.
  3. Train comparable runs.Keep the dataset version and split constant while changing only the algorithm or intended hyperparameters.
  4. Review errors.Use task-appropriate metrics and inspect where the model fails before creating a testing tab.

Reference benchmark

These values were computed with scikit-learn using the setup above. They show what one reproducible baseline looks like; they are not copied from the cited paper and are not a production guarantee.

Accuracy by model

Higher is better
Logistic Regression0.806
Random Forest0.780
Gradient Boosting0.806

F1 for churn class: 0.604, 0.535, and 0.589.

Reading the result

What the benchmark means

The two strongest accuracy values are tied, but Logistic Regression has the highest churn-class F1 in this fixed run. That makes it the clearer baseline here; a final choice should still compare recall, calibration, and retention cost.

Benchmark vs. your experiment: the chart above is a static reference. Results shown inside your dashboard are generated from your own dataset, parameters, validation split, and saved model.

Responsible use

Limitations and risk

This is a fictional telco sample. Class imbalance makes accuracy insufficient by itself; review churn-class recall, precision, calibration, and the cost of retention actions.

Before deployment

Repeat validation on recent, representative data; review subgroup errors; define a fallback; and monitor input and outcome drift.

Human decisions

Use the prediction as evidence, not as the sole decision maker, where an error could affect education, health, access, pricing, or customer treatment.
