Variable Selection

Variable selection is the process of selecting a subset of relevant features (variables) for use in model construction. In data science and machine learning, variable selection is important because it helps to reduce the complexity of the model, improve its interpretability, and prevent overfitting. There are various methods for variable selection, including filter methods, wrapper methods, and embedded methods. Filter methods involve selecting variables based on their statistical properties, such as correlation with the target variable. Wrapper methods involve selecting variables by training and evaluating the model with different subsets of variables. Embedded methods involve selecting variables as part of the model training process, such as regularization techniques like Lasso and Ridge regression. Variable selection is a crucial step in the model building process, as it can greatly impact the performance and interpretability of the model.
