Distillation of BERT-Like Models: The Theory
Webclass torch.nn.CrossEntropyLoss(weight=None, size_average=None, ignore_index=- 100, reduce=None, reduction='mean', label_smoothing=0.0) [source] This criterion computes the cross entropy loss between input logits and target. It is useful when training a classification problem with C classes. 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 … hornitex philippines inc

Web20 Feb 2024 · Cross entropy loss is mainly used for the classification problem in machine learning. The criterion are to calculate the cross-entropy between the input variables and the target variables. Code: In the following code, we will import some libraries to calculate the cross-entropy between the variables. WebThe Normalized Temperature-scaled Cross-Entropy or NT-Xent loss is a modification of the multi-class N-pair loss with an addition of the temperature (T) parameter. ... The authors employ a weighted average of the pixel-wise cross-entropy loss and the supervised NCE loss for their model, which provided a better clustering result than the cross ... Web24 Apr 2024 · Temperature: the temperature defines the "softness" of the softmax distribution that is used in the cross-entropy loss, and is an important hyperparameter. Lower values generally lead to a higher contrastive accuracy. hornito electrico bgh
