Data drift machine learning
WebMar 17, 2024 · Two major aspects of machine learning are the training data and the desired outcome. Hence, we have two types of model drift: Data drift and concept drift. Data drift. Simply put, data drift occurs when the data a model is trained on changes. The change in input data or independent variable leads to poor performance of the model. WebMar 22, 2024 · This loss in predictive power is called model drift. Model drift in machine learning. There are many types of model drift, but they can all be categorised into two broad categories: concept drift and data drift. In short data drift occurs when the properties of the independent variables change.

Set up ... WebAug 3, 2024 · Concept Drift. When we train a machine learning model on data, the model learns a function that maps the features to the target variable. As previously stated, if all things were static and nothing evolved over time, then we’d expect the relationship from the features to the target to hold true, thus the model should perform as it always has.
