Permutation importance

Concept and definition

Permutation importance

What is Permutation importance?

Permutation importance is a technique used in machine learning to assess the relative importance of features in a prediction model. The idea is to measure the impact of the random removal or permutation of a feature on the performance of the model. In general, the greater the decrease in model performance after the removal or permutation of a feature, the greater its importance to the model.

Permutation importance is useful because it helps to identify the features that are most relevant to a particular prediction problem, which can guide feature selection and model optimisation. In addition, it can be used with different machine learning algorithms, including decision trees, linear models and neural networks.

Permutation importance can be computationally expensive, as it involves training and evaluating the model several times. However, efficient implementations of the technique are available in machine learning libraries such as Scikit-learn in Python, making it easy to use for data scientists and analysts.
