GridSearchCV

参考代码

    CC = []
    gammas = []
    for i in range(-5, 16, 2):
        CC.append(2 ** i)
    for i in range(3, -16, -2):
        gammas.append(2 ** i)
    param_grid = {"C": CC, "gamma": gammas}
    gs = GridSearchCV(SVC(probability=True), param_grid, cv=10)
    gs.fit(x, y)
    print(gs.best_estimator_)
    print(gs.best_score_)
