def _calc_logits(self, X):
return self.forward(X)<EOL>
Calculate the logits.

:param X: The input data of the model contains features and feature weights.
:type X: For features: torch.Tensor of shape (batch_size, num_classes) and
    for feature weights: torch.Tensor of shape (batch_size, num_classes)
:return: The output logits of model.
:rtype: torch.Tensor of shape (batch_size, num_classes)
