Model Interpretation
Feature Importance
A measure of how much a feature contributes to the predictive power of a model.
Expanded definition
Feature importance helps in understanding which variables in a dataset have the most significant impact on the predictions made by a machine learning model. By assessing feature importance, practitioners can identify key drivers of outcomes, leading to better model interpretability and the opportunity to refine features for improved performance. Various techniques, such as permutation importance or tree-based methods, can be used to evaluate feature significance.
