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.…

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…

LLM-CAS: Dynamic Neuron Perturbation for Real-Time Hallucination Correction

Jensen Zhang, Ningyuan Liu, Yijia Fan +5

Large language models (LLMs) often generate hallucinated content that lacks factual or contextual grounding, limiting their reliability in critical applications. Existing approache…

GTMA: Dynamic Representation Optimization for OOD Vision-Language Models

Jensen Zhang, Ningyuan Liu, Keze Wang

Vision-language models (VLMs) struggle in open-world applications, where out-of-distribution (OOD) concepts often trigger cross-modal alignment collapse and severely degrade zero-s…

Failure-Driven Workflow Refinement

Jusheng Zhang, Kaitong Cai, Qinglin Zeng +4

Optimizing LLM-based workflows is typically formulated as a global search, where candidate workflows are evaluated based on a scalar metric. This paradigm, however, suffers from a…
