Project: Neural Wolfram|Alpha

Goal of the project:

Generate Wolfram Language code given natural language inputs using deep learning with artificial neural networks.

Summary of work:

Trained bi-directional LSTM recurrent neural networks, with and without attention, to generate code given English queries about indefinite integrals. Tried both character-to-character and character-to-word models.

Results and future work:

Obtained excellent performance beyond our expectations. The neural net learned to always generate valid Wolfram Language syntax (even character by character). We will train on more types of queries in the future.
