Feature Selection:Helps you answer the question: "What are the features that are most useful for a given model?" One of the reasons we need to apply this is that the number of features in your original dataset may be very very high.Benefits: Eliminates irrelevant, redundant and highly correlated features Reduce dimensionality for increased performance. As many ML models do not cope well on data with very large dimensions(many features).We can improve the situation of having too many features through dimensionality reduction.Commonly used techniques are:PCA (Principal Component Analysis)t-SNE (t-Distributed Stochastic Neighboring Entities)Feature embeddingAzure ML prebuilt modules:Filter-based feature selection: identify columns in the input dataset that have the greatest predictive powerPermutation feature importance: determine the best features to use by computing the feature importance scores*********************Data DriftData drift is change in the input data for a model.…
