Encoder-Decoder Architecture

https://d2l.ai/chapter_recurrent-modern/encoder-decoder.html

  1. I think encoder and decoder don’t have to be the same type of neural network
  2. Question answering. I applied this approach to the Conversational Question Answering (CoQA) dataset. Perplexity was 1.6. Not too bad for a very simple model.

I’ve seen Encoder/Decoder approaches used in recommender system applications before.
