Bio
I'm Hongwei Fan, a research engineer at Sensetime. I graduated from Beijing University of Posts and Telecommunications(BUPT), with the co-advision of Prof. Cewu Lu(site) and Prof. Yong-Lu Li(site) from Shanghai Jiao Tong University(SJTU). My primary research interests are 3D Scene Reconstruction & Simulation (Sensor/Physics/Traffic/...). In my spare time, I like playing with geeky things like network, parallel computing and embedded system. Besides, I'm also enthusiastic in literature and arts, especially musicals and comedies.
This website was built upon LNMP and WordPress, with theme Sakura installed. If you want to build your own personal website in this way, a detailed instruction is strongly recommended. Special thanks to the instruction of Seoimo and the theme of Mashiro.

Activity2Vec
- https://github.com/DirtyHarryLYL/HAKE-Action-Torch/tree/Activity2Vec (first author, 200+ stars)
- Activity2Vec is a fine-grained activity feature extractor, it works like a pretrained backbone network on ImageNet / COCO, which aims at extracting multi-modal activity representation for downstream tasks like VQA, captioning, clustering, etc.
- Activity2Vec contributes to a major part of HAKE(Human Activity Knowledge Engine), a large research project conducted by MVIG-SJTU team.
DIO (Discovering Interactive Objects)
- Paper: https://arxiv.org/abs/2211.07501, Code: https://github.com/DirtyHarryLYL/HAKE-AVA (co-first author)
- DIO is a large Video HOI dataset, containing 299 videos, 51 interaction classes and 1000+ object classes.
- DIO purposes a novel Video HOI Benchmark to evaluate human/object tracking and interaction detection simutaneously, and provides a strong baseline for the next generation of Video HOI.
