Finally, a Bayesian search named CBO is created and executed to find the values of config which MAXIMIZE the return value of run(job).def run(job): # The suggested parameters are accessible in job.parameters (dict) x = job.parameters["x"] b = job.parameters["b"] if job.parameters["...
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 ...

随机搜索(Random Search):随机搜索使用的是超参数的随机组合。这意味着并不会尝试所有可能的参数值,而是通过n_iter给定的固定迭代次数进行参数采样。关于Scikit-learn中超参数随机搜索的指南:https://scikit-learn.org/stable/modules/generated/sklearn.model_selection.RandomizedSearchCV.html。
By default, each trial will utilize 1 CPU, and optionally 1 GPU if available. You can leverage multipleGPUs for a parallel hyperparameter searchby passing in aresources_per_trialargument. You can also easily swap different parameter tuning algorithms such asHyperBand,Bayesian Optimization,Population-...
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 ...
