WebThe definition of CrossEntropyLoss in PyTorch is a combination of softmax and cross-entropy. Specifically. CrossEntropyLoss (x, y) := H (one_hot (y), softmax (x)) Note that … WebThe true value, or the true label, is one of {0, 1} and we’ll call it t. The binary cross-entropy loss, also called the log loss, is given by: L(t, p) = − (t. log(p) + (1 − t). log(1 − p)) As the …
WebMar 19, 2024 · These findings indicate that the cross-entropy represents a proxy for maximizing the mutual information -- as pairwise losses do -- without the need for complex sample-mining and optimization schemes. WebApr 15, 2024 · Correspondingly, the loss function of the LWI task is defined as the log-likelihood function of sequence probability or cross entropy between predicted and target character pair relation type distribution. Finally, the whole framework is learned with LWI task for pre-training and trained with CNER task for fine-tuning.
