Zilu Li

CS PhD student · UC San Diego

I work at the intersection of computer graphics, vision, and machine learning, where I build neural surrogate models to simulate the physical world, and I’ve recently become interested in multimodal post-training : )

I’m always happy to chat or explore ideas for collaboration. Feel free to email me anytime!

I'm co-advised by Ravi Ramamoorthi and Tzu-Mao Li. Previously, I was an undergraduate at Cornell, where I worked with Bharath Hariharan, Steve Marschner, and Gordon Wetzstein.

Neural Control Variates with Automatic Integration

Zilu Li*, Guandao Yang*, Qingqing Zhao, Xi Deng, Leonidas Guibas, Bharath Hariharan, Gordon Wetzstein

SIGGRAPH, 2024

We present a method that uses arbitrary neural network architectures as control variates with automatic differentiation to create unbiased, low-variance, and numerically stable Monte Carlo estimators for various problem setups.

Neural Cache for Monte Carlo Partial Differential Equation Solver

Zilu Li*, Guandao Yang*, Xi Deng, Christopher De Sa, Bharath Hariharan, Steve Marschner

SIGGRAPH Asia, 2023

Using neural field caches to reduce variance in Monte Carlo PDE solvers. Our method excels when computing is limited and enables effective bias and variance trade-off.
