Advancements and Future Directions in Loss Function Designs for Physics-Informed Neural Networks: A Comprehensive Review

This review synthesizes recent advances in loss function designs for Physics-Informed Neural Networks (PINNs), a transformative approach to solving partial differential equations (PDEs) by embedding physical laws into deep learning frameworks, to equip researchers with insights to refine PINN methodologies.

Empirical Evaluation of Open-Source Large Language Models for Retrieval-Augmented Generation in ESG Domain

Environmental, Social, and Governance (ESG) reporting is critical for corporate accountability, with Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG) offering strong potential to automate KPI extraction. However, open-source LLM performance in domain-specific ESG tasks remains insufficiently unders...

FuGuard: Client-Level Federated Unlearning via Generative Surrogates and Optimal Transport.

FuGuard is proposed, a dual-strategy federated unlearning framework, designed for efficient and ideal client-level data removal that combines the generative surrogate, which approximates the contribution of the target client, with optimal transport regularization that softly constrains model parameter drift during unle...

FedOPAL: One-Shot Federated Learning via Analytic Visual Prompt Tuning

Experimental results show that FedOPAL not only significantly outperforms the original analytical methods on several benchmarks, but also achieves accuracy comparable to state-of-the-art iterative methods while maintaining zero server-side training costs, providing a new engineering paradigm for efficient collaboration...
