Variational Gaussian Mixture Manifold Models for Client-Specific Federated Personalization

arXiv:2509.10521v1 Announce Type: new Abstract: Personalized federated learning (PFL) often fails under label skew and non-stationarity because a single global parameterization ignores client-specific geometry. We introduce VGM$^2$ (Variational Gaussian Mixture Manifold), a geometry-centric PFL framework that (i) learns client-specific parametric…

SafeSwitch: Steering Unsafe LLM Behavior via Internal Activation Signals

arXiv:2502.01042v5 Announce Type: replace Abstract: Large language models (LLMs) exhibit exceptional capabilities across various tasks but also pose risks by generating harmful content. Existing safety mechanisms, while improving model safety, often lead to overly cautious behavior and fail to fully…

Offline Contextual Bandit with Counterfactual Sample Identification

arXiv:2509.10520v1 Announce Type: new Abstract: In production systems, contextual bandit approaches often rely on direct reward models that take both action and context as input. However, these models can suffer from confounding, making it difficult to isolate the effect of…

HoloGarment: 360{deg} Novel View Synthesis of In-the-Wild Garments

arXiv:2509.12187v1 Announce Type: cross Abstract: Novel view synthesis (NVS) of in-the-wild garments is a challenging task due significant occlusions, complex human poses, and cloth deformations. Prior methods rely on synthetic 3D training data consisting of mostly unoccluded and static objects,…
