8. The computer-implemented method of claim 4 , wherein generating each equation corresponding to the explainability score of the directly connected node v is based on taking a softmax operation on the multiple functions corresponding to the multinomial distributions associated with the directly connected node v, the multiple functions being arguments to the softmax operation.
