Optical Computing with Spectrally Multiplexed Features in Complex Media

Xue Dong, K.-Y. Lion, Fei Xia, YoonSeok Baek, Ziao Wang, Niao He, et al.

Artificial intelligence (AI) has rapidly evolved into a critical technology; however, electrical hardware struggles to keep pace with the exponential growth of AI models. Free space optical hardware provides alternative approaches for large-scale optical processing, and in-memory…

Direction-Magnitude Decomposition for Low-Rank Matrix Optimization: Faster Convergence and Saddle-to-saddle Dynamics

Yudong Wei, Liang Zhang, Bingcong Li, Niao He

Low-rank matrix optimization is often carried out via the Burer-Monteiro (BM) formulation, but choosing the factorization rank $r$ is delicate and can substantially slow optimization. We propose a unified framework, termed direction-magnitude decomposition (DMD), that decomposes…
