Which feature selection method is best?

Exhaustive Feature Selection This is the most robust feature selection method covered so far. This is a brute-force evaluation of each feature subset. This means that it tries every possible combination of the variables and returns the best performing subset.

How would you derive new features from features that already exist?

Binning. Binning, (also called banding or discretisation), can be used to create new categorical features that group individuals based on the value ranges of existing features. You can use binning to create new target features you want to predict or new input features.

What are feature selection techniques?

What is Feature Selection? Feature Selection is the method of reducing the input variable to your model by using only relevant data and getting rid of noise in data. It is the process of automatically choosing relevant features for your machine learning model based on the type of problem you are trying to solve.

What are the steps for feature engineering?

Feature engineering in ML consists of four main steps: Feature Creation, Transformations, Feature Extraction, and Feature Selection. Feature engineering consists of creation, transformation, extraction, and selection of features, also known as variables, that are most conducive to creating an accurate ML algorithm.
