Part 2: Defining the full model

Did you know that it took around 6 days and 96 GPUs to train a variant of the Google Neural Machine Translator just on the English to French translation task.

In this exercise you will define a similar but much simpler encoder-decoder based neural machine translator model. Specifically, you will use the previously defined inputs and outputs and define a Keras Model object and compile the model with a given loss function and an optimizer.

Here you are provided with en_inputs (encoder input layer), en_out and en_state (encoder GRU output), de_out (decoder GRU output) and de_pred (decoder prediction) that you previously defined.

Egzersiz talimatları

Define a Keras Model which takes in the en_inputs as inputs and the decoder predictions (de_pred) as the output.
Compile the defined model by calling <model>.compile with the 'adam' optimizer, cross entropy loss and accuracy (acc) as a metric.
Print the summary of the model.
