AugAlign: Augmenting Ontology Alignment With LLMs Across the Full Alignment Pipeline

Ontology alignment identifies semantic correspondences between concepts in separately developed ontologies. Recent Large Language Model (LLM)-based ontology alignment approaches adopt a retrieve-then-prompt pipeline, in which a sentence encoder first retrieves candidate correspondences from the target ontology, and the...

Improving Long-Horizon Credit Assignment in Soft Actor-Critic for Bidirectional Utility Grid-Connected Microgrid Energy Management Systems

The microgrid energy management system coordinates the operations of multiple microgrid components. Deep reinforcement learning algorithms, such as the Soft Actor-Critic (SAC) algorithm, are well known for off-policy learning, maximum entropy, and high sample efficiency, and SAC is used as a control agent in MG-EMS. Ho...

ITCD: implicit trajectory-constrained diffusion for consistent time series imputation

The Implicit Trajectory-Constrained Diffusion network (ITCD) is proposed, which employs a two-stage diffusion architecture to mitigate the distribution shift caused by padding, thereby enabling better adaptation to realistic data and achieving more consistent imputations.

NASDiff: Noise-Aware Diffusion With Short-Trajectory Learning for Consistent Time Series Imputation

Noise-Aware Diffusion with Short-trajectory learning for consistent time series imputation (NASDiff) builds a noise-aware diffusion framework that explicitly models distinct noise sources and adopts a low-frequency-oriented diffusion process to decouple diffusion-added noise from intrinsic high-frequency component, the...
