Temperature hyperparameter是什么
WebOct 8, 2024 · By observing that temperature controls how sensitive the objective is to specific embedding locations, we aim to learn temperature as an input-dependent variable, treating it as a measure of embedding confidence. We call this approach "Temperature as Uncertainty", or TaU. WebTemperature is a hyperparameter of LSTMs (and neural networks generally) used to control the randomness of predictions by scaling the logits before applying softmax. For example, in TensorFlow’s Magenta implementation of LSTMs, temperature represents …

WebNov 8, 2024 · The temperature parameter penalizes bigger logits more than the smaller logits. The exponential function is an 'increasing function'. So if a term is already big, penalizing it by a small amount would make it much smaller (% wise) than if that term was small. Here's what I mean, exp (6) ~ 403 exp (3) ~ 20
