Temperature hyperparameter是什么

WebFeb 22, 2024 · Hyperparameters are adjustable parameters you choose to train a model that governs the training process itself. For example, to train a deep neural network, you decide the number of hidden layers in the network and the number of nodes in each layer prior to training the model. These values usually stay constant during the training process. WebAnswer (1 of 2): Temperature is a pretty general concept, and can be a useful idea for training, prediction, and sampling. Basically, the higher the temperature, the more unlikely things will be explored, the lower the temperature, the more we stick to most probable, linear world. Douglas Adams e...
