Bio

I'm Hongwei Fan, a research engineer at Sensetime. I got my bachelor and master degree from Beijing University of Posts and Telecommunications(BUPT), under the co-advision of Prof. Cewu Lu(site) from Shanghai Jiao Tong University(SJTU) and Prof. Weihong Deng(site) from BUPT. My primary research interests are Differentiable Rendering & 3D Reconstruction. In my free time, I like "playing with" parallel computing and other acceleration techniques. Besides my research, 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.

Deep Learning

• Mathematica - My first image recognition application. I built a simple object recognition project using its corresponding API. (2017-2018)
• MXNet - My first deep learning toolchain. Based on Insightface, I built a series of benchmarking tools to evaluate the discrepancy of face features (for my lab). I also used MXNet to do some research on deep transfer learning, and implemented some ops-level features like gradient reverse. (2018-2019)
• TensorFlow - I used TF when doing research on HOI, the related project is TIN, based on which I modified the pipeline for multi-GPU training. (2019)
• PyTorch - Now I often use PyTorch in my research. I have gone through the updates from v1.2 to v1.11, and used some of the new features such as NCCL, DDP, AutoGrad and MultiProcessing. (2019-)
• Slurm - I'm familiar with the Slurm + Lustre pipeline for constructing a large deep learning pipeline on cluster. (2021-)
• Misc - OpenCV, NumPy, LaTeX, ... (2017-)

Linux
