WebFrom the previous code we have a maximum length of 12 words for Spanish sentences and 6 words for English. Here we can see the advantage of using an encoder decoder model, previously we had the limitation of working with equal length sentences, so we needed to apply padding to the English sentences up to 12, now it is half. Consequently, and more … WebWe then take the final output of the LSTM, and use it as input into all of the nodes on a “decoder” LSTM (we will use Keras’ RepeatVector function to do this). At each node, the decoder LSTM takes in the output of the encoder LSTM as input, as well as the state passed to it by the previous node in the decoder LSTM.

You will probably have to see for yourself which one is better because it depends on the problem you're solving. However, I'm giving you the difference between the two approaches. Essentially, return_sequences=True returns all the outputs the encoder observed in the past, while RepeatVector repeats the very last output of the encoder.
