我们再次使用 Sci-KitLearn 库的 SVC 类,但这次我们使用 RandomSearchCV 类进行随机搜索优化。 hyperparameters = { "C": stats.uniform(500, 1500), "gamma": stats.uniform(0, 1), 'kernel': ('linear', 'rbf') } random = RandomizedSearchCV( estimator = SVC(), param_distributions = hyper...
GridSearchCV()函数的参数有待评估模型pipeline,超参数词典parameters和效果评价指标scoring。n_jobs是指并发进程最大数量,设置为-1表示使用所有CPU核心进程。在Python3.4中,可以写一个Python的脚本,让fit()函数可以在main()函数里调用,也可以在Python自带命令行,IPython命令行和IPython Notebook运行。经过网格计算后的超...
