Reinforcement learning based data assimilation for unknown state model

arXiv:2511.02286v2 Announce Type: replace Abstract: Data assimilation (DA) has increasingly emerged as a critical tool for state estimation across a wide range of applications. It is significantly challenging when the governing equations of the underlying dynamics are unknown. To this…

PromptPort: A Reliability Layer for Cross-Model Structured Extraction

arXiv:2601.06151v1 Announce Type: new Abstract: Structured extraction with LLMs fails in production not because models lack understanding, but because output formatting is unreliable across models and prompts. A prompt that returns clean JSON on GPT-4 may produce fenced, prose-wrapped, or…

Neural Operators for Biomedical Spherical Heterogeneity

arXiv:2601.03561v3 Announce Type: replace Abstract: Spherical deep learning has been widely applied to a broad range of real-world problems. Existing approaches often face challenges in balancing strong spherical geometric inductive biases with the need to model real-world heterogeneity. To solve…

Low-Dimensional Federated Knowledge Graph Embedding via Knowledge Distillation

arXiv:2408.05748v3 Announce Type: replace-cross Abstract: Federated Knowledge Graph Embedding (FKGE) aims to facilitate collaborative learning of entity and relation embeddings from distributed Knowledge Graphs (KGs) across multiple clients, while preserving data privacy. Training FKGE models with higher dimensions is typically…

Forget Many, Forget Right: Scalable and Precise Concept Unlearning in Diffusion Models

arXiv:2601.06162v1 Announce Type: new Abstract: Text-to-image diffusion models have achieved remarkable progress, yet their use raises copyright and misuse concerns, prompting research into machine unlearning. However, extending multi-concept unlearning to large-scale scenarios remains difficult due to three challenges: (i) conflicting…
