I am a master's student in the Electrical & Computer Engineering department at Cornell University, where I have the privilege of being advised by
Prof. Zhiru Zhang.
My research interests span
computer architecture,
machine learning systems (MLSys),
machine learning,
hardware compiler. I am passionate about pushing the boundaries of hardware-software co-design for efficient AI and system architectures.
I am actively seeking a Ph.D. position for Fall 2025 to continue advancing these areas of research.

SmoothE: Differentiable E-Graph Extraction
Yaohui Cai, Kaixin Yang, Chenhui Deng, Cunxi Yu, Zhiru Zhang
International Conference on Architectural Support for Programming Languages and Operating Systems (ASPLOS), 2025. [Accept Rate: 12.7%]
[Introduction]
- The first differentiable approach to e-graph extraction by relaxing the discrete optimization problem of e-node selection into a continuous, probabilistic formulation which enables parallelizable global optimization that supports any differentiable objectives.
- Implement SmoothE in PyTorch and further introduce a set of performance optimization techniques to exploit vectorized processing, sparsity, seed batching to improve the efficiency of GPU execution.
[Code] To be open-sourced soon.
[Paper] Coming up soon!
