Marco Ribeiro is giving a talk on Friday, Feb 28 at 11am – 12pm in South Hall 210.
Title: What is wrong with my model? Detection and analysis of bugs in NLP models
Abstract: I will present two projects that deal with evaluation and analysis of NLP models beyond cross validation accuracy. First, I will talk about Errudite (ACL2019), a tool and set of principles for model-agnostic error analysis that is scalable and reproducible. Instead of manually inspecting a small set of examples, we propose systematically grouping of instances with filtering queries and counterfactual analysis (if possible).
Then, I will talk about ongoing work in which we borrow insights from software engineering (unit tests, etc) to propose a new testing methodology for NLP models. Our tests reveal a variety of critical failures in multiple tasks and models, and we show via a user study that the methodology can be used to easily detect previously unknown bugs.
