About me


Yuanming Hu          胡渊鸣

I am a second-year Ph.D. student at MIT CSAIL, advised by Fredo Durand and Bill Freeman.

I graduated with honor from Tsinghua University (Yao class) in July 2017. I worked on deep learning and computer vision, during my internship with Stephen Lin at Microsoft Research Asia. My undergraduate thesis is on automatic photo post-processing using reinforcement learning and adversarial learning (presented at SIGGRAPH 2018). I completed my master thesis (ChainQueen) with Wojciech Matusik in November 2018.

My current research interests include ...

  1. Computational photography:
    • Exposure: learning infinite-resolution image processing with RL and GANs from unpaired images, based on a differentiable image editing model;
    • FC4: FCN-based color constancy with confidence-weighted pooling.
  2. Physical simulation for VFX, machine learning, and robotics:
    • ChainQueen: differentiable MLS-MPM simulator for soft robotics that enables skill learning in < 100 iterations gradient descent iterations;
    • MLS-MPM: efficient & simple MPM in 88 lines of code;
    • CPIC: rigid-deformable coupling and cutting for MPM;
    • AsyncMPM: MPM with adaptive regional time stepping.
  3. High-performance systems for computer graphics:
    • Giga-Voxel Narrowband TopOpt: topology optimization of 1,040,875,347 voxels on a single computer with an MGPCG FEM solver and SPGrid;
    • SIMD MLS-MPM: hand-optimized CPU MLS-MPM 14x faster than the previous state of the art.

In my spare time, I develop the Taichi computer graphics R&D infrastructure.
