网格搜索GridSearchCV GridSearchCV用于系统地遍历多种参数组合,通过交叉验证确定最佳效果参数。classsklearn.model_selection.GridSearchCV(estimator,param_grid, scoring=None, fit_params=None, n_jobs=1, iid=True, refit=True,cv=None, verbose=0, pre_dispatch='2*n_jobs', error_score='raise',return_...
The grid search method is the easiest to implement and understand, but sadly not efficient when the number of parameters is large and not strongly restricted under H0. Let Ω* be the space of nuisance parameters ν = (ν1, ν2,…νm) over which we maximize the p-value. A simple way...
【题目】MATLAB画出直线x=0:0.1:30 y=70*20y2(1+0.1/(10*(x+20)^2);plot(x, y,'r');grid on 答案 【解析】有运算改为点乘就行了,加减可不变,这是数组运算与矩阵的不同y=70.*log2(1+0.1./(10.*(x+20)./(.*20).^4);而且不能为零,就是 x=0.1:0.1:30。相关...
