Shapley compositions offer new method for multiclass AI prediction explanation

Researchers have introduced a novel method called Shapley compositions to explain probabilistic predictions in multiclass machine learning models. This approach extends the traditional Shapley value concept, which is typically used for scalar predictions, to handle the complex compositional nature of multiclass probability distributions. By leveraging the Aitchison geometry from compositional data analysis, Shapley compositions offer a unique and axiomatic way to quantify feature contributions on the simplex, providing a more accurate explanation for multiclass predictions.
