A Logistic Regression Python model to predict loan default.
To run the attached Jupyter notebook, create a Python 3.6.9 virtual environments with the libraries versioned in requirements.txt.
Model was trained on the German Credit Data dataset.
logreg_classifier.pickle is the trained model artifact.
Sample inputs to the scoring function are included (df_baseline.json, df_sample.json).
Model code includes a metrics function used to compute Group and Bias metrics.
The metrics function expects a DataFrame with at lease the following three columns three columns: score (predicted), label_value (actual), and gender (protected attribute).
Sample inputs to the metrics function are included (df_baseline_scored.json, df_sample_scored.json).
The output of the scoring job when the input data is df_sample.json is a JSONS file (one-line JSON records). Here are the first three output records:
