Figure 8From: Internal migration and mobile communication patterns among pairs with strong tiesPermutation feature importance for rise/decay classification. These show the permutation feature importance of each predictor used in the best model for predicting rise/decay in the mean number of calls ((a) and (b)) and the mean fraction of calls ((c) and (d)). The more positive the permutation feature importance for a particular predictor is, the more shuffling the predictor values negatively affects the model performanceBack to article page
