Data Drift Report

Drift Report service creates a statistical report based on a comparison of training and production data distributions. It compares these two sets of data by a set of statistical tests and finds deviations.
Drift report uses multiple different tests with p=.95 for different features:
Numerical features:
  • Levene's test with a trimmed mean
  • Welch's t-test
  • Mood's test
  • Kolmogorov–Smirnov test
Categorical features:
  • Chi-Square test
  • Unseen categories

Supported Models

Right now Drift Report feature works only for Models with numerical scalar fields.
