Task-Induced Riemannian Metrics for Vision Transformer Feature Spaces

The Spectral Pullback Network (SPN) is developed, which learns a low-rank version of the metric from randomized power iteration, and is distill into a $310$K-parameter importance head that predicts token importance directly from the features.

SLICEChat: Progressive In-Encoder Token Pruning for Whole-Slide Pathology Language Models

SLICEChat is introduced, a slide-level MLLM that integrates progressive token pruning within a hybrid Mamba--Transformer slide encoder, which demonstrates accurate and computationally efficient multimodal reasoning over gigapixel WSIs.

Learning to Think Like a Cartoon Captionist: Incongruity-Resolution Supervision for Multimodal Humor Understanding

Grounded in incongruity-resolution theory and expert captionist practice, IRS supervises intermediate reasoning process through structured traces that make the path from visual perception to humorous interpretation explicit and learnable.

BeyondMasks: Evaluating Causal and Physical Consistency in Video Object Removal

BeyondMasks reframes video object removal as causal scene consistency rather than local reconstruction and provides a unified framework for its evaluation, and proposes CORE, a structured vision language model based evaluation protocol that jointly measures object disappearance and after effect consistency, aligning mo...
