WebShapley computes feature contributions for single predictions with the Shapley value, an approach from cooperative game theory. The features values of an instance cooperate to achieve the prediction. The Shapley value fairly distributes the difference of the instance's prediction and the datasets average prediction among the features. WebRelative Weight Analysis is a useful technique to calculate the relative importance of predictors (independent variables) when independent variables are correlated to each other. It is an alternative to multiple regression technique and it addresses multicollinearity problem and also helps to calculate the importance rank of variables. Web9 Nov 2024 · There’s no need for data cleaning – all data types are numeric, and there are no missing data. The train/test split is the next step.
