Neural module networks (NMNs) [1] support explainable question answering over text [2] by parsing a natural-language question into a program. Such a program consists of a number of differentiable neural modules that can be executed on text in a soft way, operating over attention scores. As a result, NMNs learn to jointly program and execute these programs in an end-to-end way.

Designed mainly for compositional (multi-hop) reasoning, NMNs provide limited support for numerical reasoning. It only supports number comparison, finding min/max in a paragraph and date differences.

Student cohort

Single Semester
Double Semester

Aim/outline

This project will design new modules that enhance the numerical reasoning capabilities of NMNs so that it can handle more complex questions.
