This project attempts to reproduce the results in the paper: Generating News Headlines with Recurrent Neural Networks

How to run

Software

Data

It is assumed that you already have training and test data. The data is made from many examples (I'm using 684K examples), each example is made from the text from the start of the article, which I call description (or desc), and the text of the original headline (or head). The texts should be already tokenized and the tokens separated by spaces.

Once you have the data ready save it in a python pickle file as a tuple: (heads, descs, keywords) were heads is a list of all the head strings, descs is a list of all the article strings in the same order and length as heads. I ignore the keywords information so you can place None.

Build a vocabulary of words

The vocabulary-embedding notebook describes how a dictionary is built for the tokens and how an initial embedding matrix is built from GloVe

Train a model

train notebook describes how a model is trained on the data using Keras

Use model to generate new headlines

predict generate headlines by the trained model and showes the attention weights used to pick words from the description. The text generation includes a feature which was not described in the original paper, it allows for words that are outside the training vocabulary to be copied from the description to the generated headline.
