It’s a way to calculate the impact of a feature to the value of the target variable. The idea is you have to consider each feature as a player and the dataset as a team. Each player gives their contribution to the result of the team. The sum of these contributions gives us the … Visa mer In this example, we are going to calculate feature impact using SHAP for a neural network using Python and scikit-learn. In real-life cases, you’d probably use Keras to build a neural network, but the concept is exactly the same. For … Visa mer SHAP is a very powerful approach when it comes to explaining models that are not able to give us their own interpretation of feature importance. Such models are, for example, neural networks and KNN. Although this method … Visa mer
