Places-LT

Introduced by Ziwei Liu et al. in Large-Scale Long-Tailed Recognition in an Open World1 Jan 2019 archive 2025-07-28

Places-LT has an imbalanced training set with 62,500 images for 365 classes from Places-2. The class frequencies follow a natural power law distribution with a maximum number of 4,980 images per class and a minimum number of 5 images per class. The validation and testing sets are balanced and contain 20 and 100 images per class respectively.

24 shown of 24 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 80. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
