Feature Engineering

Why Learn Feature Engineering?

Feature Engineering for machine learning is the practice of creating new input features from your existing data to improve the accuracy of predictive models. By understanding how to manipulate data effectively, you can drastically improve the performance of machine learning algorithms. For example, understanding the importance of scaling, encoding, and normalizing data can be pivotal when building a machine learning model.

Many data science projects fail not because of a lack of data, but due to poor feature engineering techniques. By learning how to extract useful features, remove irrelevant ones, and transform raw data into a usable format, you can make your models more robust and accurate.
