Described are techniques for providing online dictionary extension of word vectors configured to provide on-line extension of existing word vector dictionaries, thus overcoming the shortcomings of conventional techniques. In one example, a dictionary extension system is employed by a computing system to ...
Creating text vectors. One portion of this is an expanded version of the code from Jian Li'sword2vecpackage with a few additional parameters enabled as the functiontrain_word2vec. The input must still be in a single file and pre-tokenized, but it uses the existing word2vec C code. For...

In this Convert Word to Vector component, we provided three different strategies: two online-training models and one pretrained model. The online-training models use your input dataset as training data, and generate vocabulary and word vectors during training. The pretrained model is already trai...
建模过程实际上与自编码器(auto-encoder)的思想很相似,即先基于训练数据构建一个神经网络,当这个模型训练好以后,我们并不会用这个训练好的模型处理新的任务,我们真正需要的是这个模型通过训练数据所学得的参数,例如隐层的权重矩阵——后面我们将会看到这些权重在Word2Vec中实际上就是我们试图去学习的“word vectors”...

The result of our work is a novel topic model called the nested variational autoencoder, which is a distribution that takes into account word vectors and is parameterized by a neural network architecture. For optimization, the model is trained to approximate the posterior distribution of the ...
而CBOW( Continuous Bagof-Words)是给定上下文,来预测input word。这两个模型均是用来进行预测的,直接目的并不是词向量。只是在训练这两个模型的过程中便会产生的参数矩阵——隐层的权重矩阵,便是Word2Vec中实际上就是我们试图去学习的“word vectors”
