After we're done with the corpora, it's now time to work on the model. This project requires again a sequence to sequence model, therefore we can use an RNN. Even more, we can reuse part of the code from the previous project: we'd just need to change how the dataset is built, and the parameters of the model. We can then copy the training script built in the previous chapter, and modify the build_dataset function, to use the Cornell dataset.
Mind that the dataset used in this chapter is bigger than the one used in the previous, therefore you may need to limit the corpora to a few dozen thousand lines. On a 4 years old laptop with 8GB RAM, we had to select only the first 30 thousand lines, otherwise, the program ran out of memory and kept swapping. As a side effect of having fewer examples, even the dictionaries are smaller, resulting in less...
