vaeac_check_mask_gen function

Function that checks the specified masking scheme

vaeac_check_mask_gen(mask_gen_coalitions, mask_gen_coalitions_prob, x_train)

Arguments

• mask_gen_coalitions: Matrix (default is NULL). Matrix containing the coalitions that the vaeac model will be trained on, see specified_masks_mask_generator(). This parameter is used internally in shapr when we only consider a subset of coalitions, i.e., when n_coalitions $< 2^{n_{\text{features}}}$, and for group Shapley, i.e., when group is specified in explain().
• mask_gen_coalitions_prob: Numeric array (default is NULL). Array of length equal to the height of mask_gen_coalitions containing the probabilities of sampling the corresponding coalitions in mask_gen_coalitions.
• x_train: A data.table containing the training data. Categorical data must have class names $1,2,\dots,K$.

Returns

The function does not return anything.
