Web11. jun 2024. · one_hot () takes a torch.int64 argument and returns a torch.int64 result. Pytorch doesn’t even permit such integer-valued tensors to have requires_grad = True (because it doesn’t make sense). *) To be more precise, a loss function could depend on the result of one_hot () and also on the results of some differentiable tensor operations. In digital circuits and machine learning, a one-hot is a group of bits among which the legal combinations of values are only those with a single high (1) bit and all the others low (0). A similar implementation in which all bits are '1' except one '0' is sometimes called one-cold. In statistics, dummy variables represent a similar technique for representing categorical data.

WebIn reply to surya_mudgal: The two versions of your constraints are not equivalent. a ^ (b != none_dist) ^ d is true of one operand, or all three operands are true. That is not the same as one-hot. b can only have the values low_dist, medium_dist, or nudist. So (b != none_dist) must always be true. — Dave Rich, Verification Architect, Siemens EDA.
