Definition

Feature extraction involves transforming raw data into a set of features that better represent the underlying problem to the predictive models, resulting in improved model accuracy. This technique reduces the number of random variables under consideration by obtaining a set of principal features. It is commonly used in image processing, signal analysis, and text mining to isolate relevant characteristics from complex datasets.

Summary
