Shared Interest: Measuring Human-AI Alignment to Identify Recurring Patterns in Model Behavior

1 code implementation20 Jul 2021 Angie Boggust, Benjamin Hoover, Arvind Satyanarayan, Hendrik Strobelt

Saliency methods -- techniques to identify the importance of input features on a model's output -- are a common step in understanding neural network behavior.

LMdiff: A Visual Diff Tool to Compare Language Models

1 code implementation EMNLP (ACL) 2021 Hendrik Strobelt, Benjamin Hoover, Arvind Satyanarayan, Sebastian Gehrmann

While different language models are ubiquitous in NLP, it is hard to contrast their outputs and identify which contexts one can handle better than the other.
