Token based text embedding trained on English Wikipedia corpus.
Module URL: https://tfhub.dev/google/Wiki-words-500/1
Text embedding based on skipgram version of word2vec with 1 out-of-vocabulary bucket. Maps from text to 500-dimensional embedding vectors.
embed = hub.Module("https://tfhub.dev/google/Wiki-words-500/1") embeddings = embed(["cat is on the mat", "dog is in the fog"])
Skipgram model, hierarchical softmax, sub-sampling 1e-5.
The module takes a batch of sentences in a 1-D tensor of strings as input.
The module preprocesses its input by splitting on spaces.
Out of vocabulary tokens
Module maps all out-of-vocabulary tokens into one bucket that is initialized with zeros.
Word embeddings are combined into sentence embedding using the
