New Media Manager Author Introduction Liú Shūlóng, currently an engineer in the technology department of Daguan Data, with interests primarily in natural language processing and data mining. Word2vec is one of the achievements of the Google research team, and as a mainstream tool for obtaining distributed word vectors, it has a wide range of applications … Read more
word2vec was launched by Google in 2013. The methods for obtaining word vectors, CBOW and Skip-gram models, are elaborated in the paper “Efficient Estimation of Word Representations in Vector Space.” The strategies for efficiently training models, Hierarchical Softmax and Negative Sampling, are discussed in “Distributed Representations of Words and Phrases and their Compositionality.” Since the … Read more

Comparison of Models (Model Architectures Section of the Paper) Before the introduction of word2vec, NNLM and RNNLM trained word vectors by training language models using statistical methods. This section mainly compares the following three models: Feedforward Neural Net Language Model Recurrent Neural Net Language … Read more
This Article Overview: 1. Background Knowledge Word2Vec is a type of language model that learns semantic knowledge from a large amount of text data in an unsupervised manner, and is widely used in natural language processing. Word2Vec is a tool for generating word vectors, and word vectors are closely related to language models. Therefore, we … Read more
word2vec Word2Vec is a model used to generate word vectors. These models are shallow, two-layer neural networks trained to reconstruct linguistic word texts.The network represents words and needs to predict the input words in adjacent positions. In Word2Vec, under the bag-of-words model assumption, the order of words is not important. After training, the Word2Vec model … Read more

1. Review DNN Training Word Vectors Last time we discussed how to train word vectors using the DNN model. This time, we will explain how to train word vectors using word2vec. Let’s review the DNN model for training word vectors that we discussed earlier: In the DNN model, we use the CBOW or Skip-gram mode … Read more
