Reinforcement-Learned Unequal Error Protection for Quantized Semantic Embeddings

arXiv:2601.00186v1 Announce Type: new Abstract: This paper tackles the pressing challenge of preserving semantic meaning in communication systems constrained by limited bandwidth. We introduce a novel reinforcement learning framework that achieves per-dimension unequal error protection via adaptive repetition coding. Central…

Unknown Aware AI-Generated Content Attribution

arXiv:2601.00218v1 Announce Type: new Abstract: The rapid advancement of photorealistic generative models has made it increasingly important to attribute the origin of synthetic content, moving beyond binary real or fake detection toward identifying the specific model that produced a given…

Episodic Contextual Bandits with Knapsacks under Conversion Models

arXiv:2507.06859v2 Announce Type: replace Abstract: We study an online setting, where a decision maker (DM) interacts with contextual bandit-with-knapsack (BwK) instances in repeated episodes. These episodes start with different resource amounts, and the contexts’ probability distributions are non-stationary in an…

Robust Graph Fine-Tuning with Adversarial Graph Prompting

arXiv:2601.00229v1 Announce Type: new Abstract: Parameter-Efficient Fine-Tuning (PEFT) method has emerged as a dominant paradigm for adapting pre-trained GNN models to downstream tasks. However, existing PEFT methods usually exhibit significant vulnerability to various noise and attacks on graph topology and…
