  • InferSent (INF)
  • GSE (Google Sentence Encoder)

  InferSent (INF) = pre-trained encoder that was developed by Facebook Research. It is a BiLSTM with max pooling, trained on the SNLI dataset, 570k English sentence pairs labelled with one of three categories: entailment, contradiction or neutral.

  GSE (Google Sentence Encoder) = Google’s answer to Facebook’s InferSent. It comes in two forms:

  • an advanced model that takes the element-wise sum of the context-aware word representations produced by the encoding subgraph of a Transformer model
  • a simpler Deep Averaging Network (DAN) where input embeddings for words and bigrams are averaged together and passed through a feed-forward deep neural network.
