Data Drift

Data Drift

Data drift, feature drift, covariate drift and input drift all refer to a shift in the statistical properties of the independent variable(s), i.e. a drift in the feature distributions and the correlations between variables. This drift can result in data changes due to seasonality, consumer preferences, the addition of new products or other factors.
