NSFC-62206101: Fundamental Limits of Pruning Deep Neural Network Models via Random Matrix Methods
This project (2023.01-2025.12) is led by myself, and focuses on the fundamental theoretical limits of pruning as well as quantization of deep neural networks. The objective of this project is to propose, by developing the mathematical tools of random matrix theory, high-dimensional statistics, and optimization theory, a quantitative theory to characterize the “performance and complexity tradeoff” in modern deep neural nets.
CCF-Hikvision Open Fund 20210008: Random Matrix Theory and Information Bottleneck for Neural Network Compression
This project is led by Prof. Kai Wan and myself as PI, and investigates efficient compression schemes of large-scale neural network models with strong theoretical guarantees. The project leads to the following scientific publications:
H. Tiomoko, Z. Liao, R. Couillet, “Random matrices in service of ML footprint: ternary random features with no performance loss”, The Tenth International Conference on Learning Representations (ICLR'2022), 2022. preprint
L. Gu, Y. Du, Y. Zhang, D. Xie, S. Pu, R. C. Qiu, Z. Liao, “Lossless Compression of Deep Neural Networks: A High-dimensional Neural Tangent Kernel Approach”, 2022.
