In this video we introduce sequence to sequence models, useful for translation.

In this tutorial, we are going to look at one of the coolest applications of LSTMs: Seq2Seq models. The canonical example of Seq2Seq is translation, and in fact Seq2Seq models are what Google Translate uses.

We are going to build a Seq2Seq model that takes in strings of arithmetic equations (e.g. “10 + 12”) and returns the answer to that equation (“22”). What makes this really amazing is that the model knows nothing about arithmetic - it is ‘translating’ the strings.

How does Seq2Seq work

Let’s go through how the LSTM works on our simple “10 + 12” = “22” model.


Go into the seq2deq directory and open up Here you will see the full code for implementing our arithmetic model.
