Feature Engineering for Machine Learning: A Practical Learning Guide
Feature engineering is one of the most important skills in practical machine learning. A model does not learn from business reality directly. It learns from the columns, values, categories, dates, numbers, text, and signals that you give it. This guide explains feature engineering in plain language and can be used as study material before learning Keras, BigQuery ML, or Vertex AI Feature Store. Quick Answer Feature engineering means transforming raw data into model-ready features. Good features are relevant to the prediction goal, available at prediction time, represented in a useful format, and tested through model evaluation. ...
