Cross-entropy can be used to define a loss function in machine learning and optimization. The true probability is the true label, and the given distribution is the predicted value of the current model. This is also known as the log loss (or logarithmic loss or logistic loss); the terms "log loss" and "cross-entropy loss" are used interchangeably. More specifically, consider a binary regression model which can be used to classify observations … WebOct 25, 2024 · Burn is a common traumatic disease. After severe burn injury, the human body will increase catabolism, and burn wounds lead to a large amount of body fluid loss, with a high mortality rate. Therefore, in the early treatment for burn patients, it is essential to calculate the patient’s water requirement based on the percentage of the burn …

WebMay 23, 2024 · Let’s first look at the self-supervised version of NT-Xent loss. NT-Xent is coined by Chen et al. 2024 in the SimCLR paper and is short for “normalized temperature-scaled cross entropy loss”. It is a modification of the multi-class N-pair loss with addition of the temperature parameter (𝜏) to scale the cosine similarities: WebOct 5, 2024 · ce_loss (X * 1000, torch.argmax (X,dim=1)) # tensor (0.) nn.CrossEntropyLoss works with logits, to make use of the log sum trick.
