Feature engineering is crucial for maximizing the performance of machine learning models. By creating and processing meaningful features, even simple algorithms can achieve superior results. Key techniques include aggregation, differences and ratios, age encoding, indicator encoding, one-hot encoding, and target encoding. Effective feature processing involves outlier treatment, handling missing values, scaling, dimensionality reduction, and transforming targets to normal distribution.
