How the ranking works
Counts are links between published ChatPPG pages: a paper or model page that names the dataset it used, and that dataset's page. Unpublished papers and models are excluded, and nothing is inferred from titles or abstracts.
This page keeps only datasets whose ChatPPG record lists IMU among its recorded signals, and ranks them against each other. The rank column is the rank within IMU datasets; the overall ranking covers every dataset.
Datasets are ranked by total links (papers plus models); ties share a rank. Pretrain, train and eval columns count only links whose source states that role, so they can add up to less than the total; a dash means no link to that dataset states a role. The table refreshes with every research hub sync.
Licence, signals and tasks come from each dataset's ChatPPG record. Check the dataset page and its source before you use the data.
FAQ
What is the most used IMU dataset?
PPG-DaLiA, with 47 links from published ChatPPG pages (28 papers and 19 models). Next are WESAD (44), MESA Sleep (28) and PAMAP2 (24).
How many IMU datasets are ranked here?
53 datasets list IMU among their recorded signals and have at least one published paper or model linking to them. Together they have 226 paper links and 111 model links.
Which IMU datasets are used most for human activity recognition?
27 IMU datasets in this ranking list human activity recognition as a task. The most used are PAMAP2 (24), WISDM AR v1.1 (19) and CAPTURE-24 (14).
Which IMU datasets do the most models use?
PPG-DaLiA (19 models), WESAD (16 models) and MESA Sleep (7 models). Model counts include foundation models and task models with a published ChatPPG page.
Which IMU datasets are used most for pretraining?
Where the source states a role, the most common pretraining datasets are MESA Sleep (5), NHANES 2011-2012 Physical Activity Monitor - Raw Data 80hz (PAX80_G) (3) and PPG-DaLiA (1).
Which IMU datasets are used most for evaluation?
Where the source states a role, the most common evaluation datasets are PPG-DaLiA (22), WESAD (21) and PAMAP2 (6).
How are these counts calculated?
Each count is a link between two published ChatPPG pages: a paper or model page that lists the dataset it used, and the dataset's own page. 226 links come from papers and 111 from models. Unpublished papers and models are not counted, and no link is inferred. A dataset is included when its ChatPPG record lists IMU as a recorded signal.
Other rankings: all datasets, PPG datasets, ECG datasets, EDA datasets, rPPG datasets. Browse all datasets, or open the papers that use PPG-DaLiA. Benchmarks by dataset: leaderboards.
