Additive Margin Softmax Loss (AM-Softmax) by Fathy Rashad

WebApr 6, 2024 · PyTorch Margin Ranking Loss Function torch.nn.MarginRankingLoss The Margin Ranking Loss computes a criterion to predict the relative distances between inputs. This is different from other loss functions, like MSE or Cross-Entropy, which learn to predict directly from a given set of inputs. WebMay 4, 2024 · Softmax Implementation in PyTorch and Numpy. A Softmax function is defined as follows: A direct implementation of the above formula is as follows: def softmax (x): return np.exp (x) / np.exp (x).sum (axis=0) Above implementation can run into arithmetic overflow because of np.exp (x). To avoid the overflow, we can divide the numerator and ... WebMar 15, 2024 · MultiLabelSoftMargin’s fomula is also same with BCEWithLogitsLoss.
