WebHyperOpt是一个用于优化超参数的Python库。以下是使用HyperOpt优化nn.LSTM代码的流程： 1. 导入必要的库. import torch import torch.nn as nn import torch.optim as optim from hyperopt import fmin, tpe, hp 2. 创建LSTM模型 WebHyperopt provides a function named 'fmin()' for this purpose. We need to provide it objective function , search space , and algorithm which tries different combinations of hyperparameters. It'll then use this algorithm to minimize the value returned by the objective function based on search space in less time. Web31 jan. 2024 · Optuna. You can find sampling options for all hyperparameter types: for categorical parameters you can use trials.suggest_categorical; for integers there is trials.suggest_int; for float parameters you have trials.suggest_uniform, trials.suggest_loguniform and even, more exotic, trials.suggest_discrete_uniform; … carolina\u0027s uq
