在使用预训练的embedding层的时候,一定要注意词表的index,在word2vec中, model.wv.index2word 这个是一个list, index就是词的index,这个是固定的,即便是换到linux平台,这个index也是不变的,所以使用这个。 w2v_for_s2s = Word2Vec.load('model/word2vec_6_3_word.bin') word2idx = {"UNK": 0} # v...
word2vec词向量Word2vec是常用的词嵌入(word embedding)模型。该PaddleHub Module基于Skip-gram模型,在海量百度搜索数据集下预训练得到中文单词预训练词嵌入。其支持Fine-tune。Word2vec的预训练数据集的词汇表大小为1700249,word embedding维度为128。 SimNet(Similarity Net) 是一个计算短文本相似度的框架,主要包括 ...

在2014年的时候,也就是大概在 word2vec 的时代,第一次见证像神经网络这种方法,其实可以应用到 LP 这一领域里的,随着深度学习或者是神经网络技术跟 LP 的技术文化产生的一些结合,也就是让 LP 成为了一个相对比较火热的领域。 但是一个比较重要的提出,也就是 transformer 这个架构的提出,在此之前深度学习应用在 ...
抽取feature作为word_embeddiing,送入LSTM+CRF 分别进行两种方式的测试,另外加入使用同样语料训练word2vec获得的词向量进行对比. 直接使用albert_zh提供的tiny版,fine-tuning效果如下: INFO:tensorflow: eval_f = 0.7053323 INFO:tensorflow: eval_precision = 0.7127047 INFO:tensorflow: eval_recall = 0.699311 INFO:te...

what we discussed about bidirectional language models earlier. Taking a cue from this article, “ELMo word vectors are computed on top of a two-layer bidirectional language model (biLM). This biLM model has two layers stacked together. Each layer has 2 passes — forward pass and backward pass...
