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. – WebApr 7, 2024 · The BCAM leverages the binary state of FeFET and performs hamming distance calculations, while the MCAM leverages the multilevel state of FeFET and performs exact search. In this illustration, we describe the operation principles of a BCAM design using an 1FeFET structure per cell.
