The Super Learner algorithm is relatively straightforward to implement on top of the scikit-learn Python machine learning library. In this section, we will develop an example of super learning for both regression and classification that you can adapt to your own problems. Super Learner for Regressio...
MLR3(Machine Learning in R 3)实际上包含的学习器(Learner)数量远超过5个,具体数量可能会随着库的更新而变化。以下是关于MLR3的一些详细信息: MLR3 Learners的基础概念 MLR3是一个R语言的机器学习框架,它提供了一个统一的接口来处理各种机器学习任务。学习器是MLR3中的核心概念,它们是用于从数据中学习模型的软件...

假设后层神经元的输入都为正(e.g. x>0 elementwise in f=wTx+b),那么对w求局部梯度则都为正,这样在反向传播的过程中w要么都往正方向更新,要么都往负方向更新,导致有一种捆绑的效果,使得收敛缓慢。这是sigmoid函数容易出现的问题,而tanh函数的映射特点很好的避开了这个问题。因而在实际使用中,人们会更经常使...
