Скачать или смотреть Feature Engineering – What is a feature

Feature engineering is the process of creating new features or modifying existing features from raw data to improve the performance of a machine learning model.

In this video, you learn more about what a feature actually is. Here are some the most important ideas:

✅ Feature is a column in a machine learning data set used for prediction of the model

✅ Feature engineering involves selecting, creating, and removing features relevant to the problem being solved

✅ A feature has to be correlated with the target variable (dependent variable)

✅ If two features are almost the same, only one needs to be selected for prediction

✅ After training the model, each feature is associated with a weight to reflect its importance in the prediction.
