• The Shapley value returns a simple value per feature, but no prediction model like LIME.

• cannot be used to make statements about changes in prediction for changes in the input,

• The “game” is the prediction task for a single instance of the dataset

• The “gain” is the actual prediction for this instance minus the average prediction for all instances
