Difference between ReLU、LReLU、PReLU、CReLU、ELU、SELU ://www.cnblogs.com/jins-note/p/9646602.html参考:https://blog.csdn.net/qq_20909377/article/details/79133981https...,防止了梯度爆炸,但是正半轴坡度简单的设成了1。而selu的正半轴大于1,在方差过小的的时候可以让它增大,同时防止了梯度消失。这...
并且我们假设对应的T_y为输出的词向量的长度(之前我们有定义过T_x为输入的词向量的长度)。 需要提一嘴的是,论文中对RNN中的隐藏状态节点的激活函数作了修改,但不是LSTM,而是一个叫作门隐藏单元(gated hidden unit)的东西 (Cho. K,参考文献4)。比方说在decoder结构中,就是 \begin{cases}s_i = f(s_{i...

摘要 本文将介绍一种常用的神经网络—循环神经网络(recurrent neural network,RNN)以及循环神经网络的一个重要的变体—长短时记忆网络(long short-term memory,LSTM). 循环神经网络 循环神经网络的主要用途是处理和预测序列数据.传统的卷积神经网络(CNN)或者全连接神经网络(FC)都是从输入层到隐含层再到输出层,层与...
