然后调用 fit 函数在训练集上进行网格搜索和交叉验证,找到最佳超参数组合。 打印最佳超参数组合和对应模型性能评分:打印出通过网格搜索方法得到的最佳超参数组合和对应的负均方误差(Mean Squared Error, MSE)得分。 随机搜索方法:使用Randomized...
Run grid search on SLURM GPU cluster from test_tube.hpc import SlurmCluster # hyperparameters is a test-tube hyper params object hyperparams = args.parse() # init cluster cluster = SlurmCluster( hyperparam_optimizer=hyperparams, log_path='/path/to/log/results/to', python_cmd='python3' )...
Now, let’s define the hyperparameter space to implement random search. This parameter space can have a bigger range of values than the one we built for grid search, since random search does not try out every single combination of hyperparameters. It randomly samples hyperparameters to find th...

print(grid_search.best_params_) 1. 随机搜索 随机搜索是一种通过在给定的超参数空间中随机抽样来寻找最佳参数组合的方法。相比于网格搜索,它能够更有效地搜索到较大超参数空间中的最佳组合。 在Python中,我们可以使用scikit-learn库的RandomizedSearchCV函数来进行随机搜索。使用方法与网格搜索类似,只是将GridSearchCV...
