# openaiotlab/CUHK-X > A large-scale multimodal dataset and benchmarks for human action recognition, understanding and reasoning: 64,267 samples across seven time-aligned modalities (RGB, IR, Thermal, Depth, mmWave Radar, Skeleton, IMU). - Magnitude: 0.0 out of 10 — Steady - Stars: 303 total · +0 stars on 2026-09-24 (UTC), ≈ 0 by evening - Star trust: star growth looks organic - Category: Science & research · Language: Python · Created: 2026-09-07 · Last push: 2026-09-20 - GitHub: https://github.com/openaiotlab/CUHK-X · Page: https://gitnova.dev/en/r/openaiotlab/CUHK-X ## Useful for - Train a HAR baseline on IMU, mmWave or skeleton data - Evaluate VLMs (QwenVL, InternVL, Video-LLaVA) on captioning and next-action prediction - Compare multimodal fusion strategies under cross-subject and cross-domain protocols ## Why it’s here - The repository is 17 days old and already has 303 stars. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 9 - Issues and pull requests: 0 - Watchers: 3 - Average over the last week: 0 per day - Usual pace: 17 per day - Latest release: v1.0.0 (2026-09-07) ## Stars per day, last 30 days (oldest → newest, today is partial) 2026-09-30 … 2026-10-29: None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None ## Magnitude by day, last 12 days 09-13 0.3, 09-14 0.1, 09-15 0.1, 09-16 0.1, 09-17 0.1, 09-18 0.0, 09-19 0.0, 09-20 0.4, 09-21 0.4, 09-22 0.1, 09-23 0.1, 09-24 0.0 --- Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
