Witryna9 kwi 2024 · 1.为什么要使用激活函数 因为线性函数能拟合的模型太少，多层线性神经网络的叠加仍为线性，加上非线性可以改善拟合效果。2.激活函数的要求 非线性，可微（反向传播）。3.常用的激活函数 Sigmoid 能够把输入的连续实值变换为0和1之间的输出。 缺点：当输入值特别大或特别小时函数的梯度会很小 ... WitrynaTypeError: 'LogisticRegression' object is not callable in logistic regression score:4 Accepted answer This is due to: t_pred = logreg (X_test) You need to use a method of the object logreg, not supply the params directly to it. Notice how you used logreg.fit (). fit () is a method which handles the training data.
Witryna6.2.2 Univariate feature selection. Scikit-learn exposes feature selection routines as objects that implement the transform () method. For instance, we can perform a χ 2 test to the samples to retrieve only the two best features as follows: X, y = load_iris (return_X_y=True, as_frame=True) # Load the iris data set X.
