Real-Time FJ/MAC PDE Solvers via Tensorized, Back-Propagation-Free Optical PINN Training

no code implementations31 Dec 2023 Yequan Zhao, Xian Xiao, Xinling Yu, Ziyue Liu, Zhixiong Chen, Geza Kurczveil, Raymond G. Beausoleil, Zheng Zhang

Despite the ultra-high speed of optical neural networks, training a PINN on an optical chip is hard due to (1) the large size of photonic devices, and (2) the lack of scalable optical memory devices to store the intermediate results of back-propagation (BP).

Tensor-Compressed Back-Propagation-Free Training for (Physics-Informed) Neural Networks

no code implementations18 Aug 2023 Yequan Zhao, Xinling Yu, Zhixiong Chen, Ziyue Liu, Sijia Liu, Zheng Zhang

Backward propagation (BP) is widely used to compute the gradients in neural network training.

Knowledge-aided Federated Learning for Energy-limited Wireless Networks

no code implementations25 Sep 2022 Zhixiong Chen, Wenqiang Yi, Yuanwei Liu, Arumugam Nallanathan

Inspired by this, we define a new objective function, i. e., the weighted scheduled data sample volume, to transform the inexplicit global loss minimization problem into a tractable one for device scheduling, bandwidth allocation, and power control.

Efficient Wireless Federated Learning with Partial Model Aggregation

no code implementations20 Apr 2022 Zhixiong Chen, Wenqiang Yi, Arumugam Nallanathan, Geoffrey Ye Li

On this basis, we maximize the scheduled data size to minimize the global loss function through jointly optimize the device scheduling, bandwidth allocation, computation and communication time division policies with the assistance of Lyapunov optimization.
