Feature Engineering Intuition
Build an intuitive understanding of feature engineering for machine learning model.
We'll cover the following...
Feature engineering defined
Feature engineering is the process of using business domain and technical knowledge to extract features from raw data. Extracted features transform raw data into a format that can improve the predictive performance of machine learning algorithms.
This definition has essential implications for machine learning practitioners:
Machine learning algorithms are not guaranteed to learn from raw data.
Machine learning algorithms might learn the wrong things from raw data.
Feature engineering is an art where domain expertise and technical knowledge are vital.
Feature engineering is required to craft the most ...
