值得注意的是特征“标准化”(Normalize features)的操作,如果去掉这一部分,在 train 上还是有不错的表现,但在 test 上有所下降(轻微下降)。 神经网络模型: classNeuralNet(nn.Module):''' A simple fully-connected deep neural network '''def__init__(self,input_dim):super(NeuralNet,self).__init__()...

CART是Classification And Regression Tree,这里以Regression Tree为例预习一下回归树。 回归树,或者广义的决策树的工作原理与传统基于梯度下降迭代的Neural Network,或者直接求解析解的线性回归不太一样,它并不是通过某种线性或者非线性的映射,或者变换来进行预测,实现起来也比较反直觉,它的数据结构是一颗二叉树,详细的...
