在 Scikit 中找到最佳超参数时出现 ValueError 使用 GridSearchCV 学习 LogisticRegression

ValueError while finding best hyperparameter in Scikit learn LogisticRegression using GridSearchCV

在使用 GridSearchCV 对 LogisticRegression 进行超参数调整时,出现错误 ValueError: Invalid parameter Hparam

估算器:

LogisticRegression(C=1.0, class_weight=None, dual=False, fit_intercept=True, intercept_scaling=1, max_iter=100, multi_class='ovr', n_jobs=-1, penalty='l1', random_state=None, solver='liblinear', tol=0.0001, verbose=1, warm_start=False)

我在下面写了我的代码:

hparam=[]
a = 0.0001
while(a<100000):
    hparam.append(a)
    a*=2
LReg = LogisticRegression(penalty='l1',verbose=1,n_jobs=-1)
param_grid = {'Hparam':hparam}
grid_ = GridSearchCV(LReg, param_grid, scoring='roc_auc', cv=10)
grid_.fit(xtr_,ytr_)

Refer sci-kit Logistic Regression,Hparam 未列为逻辑回归的超参数
