When your ML model is in production, you might observe data and prediction drift: a meaningful change in the input data distributions and model output. In cases where you don't get the true labels or actual values fast, this drift might be the only proxy for the model performance. Drift analysis can also be helpful in debugging the model performance drop. But how exactly to evaluate it in practice? Should you look at descriptive feature statistics, apply statistical tests to compare distributions, and which exactly? In this talk, I will give an overview of the possible approaches to drift detection, and how to implement and visualize the results.
