Definition
Plain language
A benchmark suite for testing whether sequence models can handle very long inputs.
As stated in the literature
A standardized benchmark for evaluating long-context sequence models on tasks like ListOps, image classification, and document matching, used in AIRA-Design's attention-mechanism experiments.
Also called: LRA
Why it matters: It's a common testbed for any architecture claiming to handle long sequences better than vanilla attention.
For example, a model might be tasked with classifying a 4000-token document or matching two long byte sequences to test how its accuracy holds up at length.
