Modular Diffractive Neural Networks Using Cascaded Metasurfaces

2025 · Laser & Photonics Review

Abstract An all‐optical diffractive neural network (DNN), as the fusion of optics and artificial intelligence, utilizes light‐based computational architecture, providing potential beyond Moore's law limitations due to their low energy consumption and high parallel processing …

RPM-MCTS: Knowledge-Retrieval as Process Reward Model with Monte Carlo Tree Search for Code Generation

2025 · arXiv (Cornell University)

Tree search-based methods have made significant progress in enhancing the code generation capabilities of large language models. However, due to the difficulty in effectively evaluating intermediate algorithmic steps and the inability to locate and timely …

MTRL-CG: Multi-Task Reinforcement Learning Method with Spectral Clustering-Based Task Grouping

2026 · Proceedings of the AAAI Conference on Artificial Intelligence

Multi-task reinforcement learning (RL) aims to enhance agent performance across multiple tasks by enabling effective knowledge transfer. However, these methods adopt a fully shared policy across all tasks without explicitly distinguishing between related and conflicting …
