"Web@mark My idea does not include Hamming loss. In fact, you cannot use Hamming loss as a criterion for optimizing a model's weights with Stochastic Gradient Descend (SGD): The gradient of the Hamming loss is zero almost everywhere. Therefore, you must use a "proxy loss", e.g., cross entropy. – " - Binary hamming distance
