WebbA dependence plot is a scatter plot that shows the effect a single feature has on the predictions made by the model. In this example, the property value increases significantly when the average number of rooms per dwelling is higher than 6. Each dot is a single prediction (row) from the dataset. The x-axis is the actual value from the dataset. WebbSHAP provides global and local interpretation methods based on aggregations of Shapley values.
