simpleRNN 训练集为<爱丽丝梦境>英文版txt文档,目标:根据随机给出的10个字符,生成可能的后100个字符 词向量空间生产 In [4]: INPUT_FILE = "./data/alice_in_wonderland.txt" In [5]: fin = open(INPUT_FILE, 'rb') ...: lines = [] ...: for line in fin: ...: line = line.strip().lower() ...: line…
Keras api 提前知道: BatchNormalization, 用来加快每次迭代中的训练速度 Normalize the activations of the previous layer at each batch, i.e. applies a transformation that maintains the mean activation close to 0 and the activation standard deviation close to 1. TimeDistri…
Word Embedding Word Embedding是一种词的向量表示,比如,对于这样的"A B A C B F G"的一个序列,也许我们最后能得到:A对应的向量为[0.1 0.6 -0.5],B对应的向量为[-0.2 0.9 0.7]. 之所以希望把每个单词变成一个向量,目的还是为了方便计算,比如"求单词A的同义词",就可以通过"求与单词A在cos距离下最相似的向量"来做到. 那么如何进行词嵌入呢?目前主要有三种算法: Embedding…
