问如何选择网格搜索(当使用trainer.hyperparameter_search时)？EN简单地说，关键字就是用户在使用搜索引擎时，输入的能够最大程度概括用户所要查找的信息内容。云计算的优势之一是公有云供应商提供了数十个云区域供企业决定在哪里托管工作负载时进行选择。选择正确的云区域对于优化成本、性能、可靠性等很重要。不要默认使用离企业最近的云区域或云计算提供商建议的任...

What is more, inspired by the active learning, we propose 'uncertainty' metric to search for hyper-parameters under unsupervised setting. The 'uncertainty' uses entropy to describe the learning status of the current discriminator. The smaller the 'uncertainty', the more stable the discriminator ...

Bayesian optimisation for smart hyperparameter search Fitting a single classifier does not take long, fitting hundreds takes a while. To find the best hyperparameters you need to fit a lot of classifiers. What to do? This post explores the inner workings of an algorithm you can use to reduce...
Step 1: Specify hyperparameter search spaceAfter you’ve cloned the repo locally, let’s start making some changes to specify hyperparameters. Open the file generate_hyperparam_combinations.py and update the hyper_params variable to specify the hyperparameter space that you wish to cover. You ...
