Definition

Dataset shift occurs when the distribution of data used to train a machine learning model differs from the distribution of data encountered during inference. This discrepancy can lead to significant performance degradation. Common types include covariate shift, prior probability shift, and concept drift. Addressing dataset shift is critical for ensuring model robustness and generalization in real-world applications, often requiring techniques like domain adaptation or continuous monitoring.

Summary

Dataset shift refers to the phenomenon where the statistical properties of the input data change between training and deployment.
