Spectral Gating Networks

Jusheng Zhang, Yijia Fan, Kaitong Cai +5

Gating mechanisms are ubiquitous, yet a complementary question in feed-forward networks remains under-explored: how to introduce frequency-rich expressivity without sacrificing sta…

Rational ANOVA Networks

Jusheng Zhang, Ningyuan Liu, Qinhan Lyu +2

Deep neural networks typically treat nonlinearities as fixed primitives (e.g., ReLU), limiting both interpretability and the granularity of control over the induced function class.…

Why Keep Your Doubts to Yourself? Trading Visual Uncertainties in Multi-Agent Bandit Systems

Jusheng Zhang, Yijia Fan, Kaitong Cai +6

Vision-Language Models (VLMs) enable powerful multi-agent systems, but scaling them is economically unsustainable: coordinating heterogeneous agents under information asymmetry oft…

Self-Rewarded Multimodal Coherent Reasoning Across Diverse Visual Domains

Jesen Zhang, Ningyuan Liu, Kaitong Cai +5

Multimodal LLMs often produce fluent yet unreliable reasoning, exhibiting weak step-to-step coherence and insufficient visual grounding, largely because existing alignment approach…

RevFFN: Memory-Efficient Full-Parameter Fine-Tuning of Mixture-of-Experts LLMs with Reversible Blocks

Ningyuan Liu, Jing Yang, Kaitong Cai +1

Full parameter fine tuning is a key technique for adapting large language models (LLMs) to downstream tasks, but it incurs substantial memory overhead due to the need to cache exte…

FlashVLM: Text-Guided Visual Token Selection for Large Multimodal Models

Kaitong Cai, Jusheng Zhang, Jing Yang +4

Large vision-language models (VLMs) typically process hundreds or thousands of visual tokens per image or video frame, incurring quadratic attention cost and substantial redundancy…
