FastBench: Can Streaming VLMs Perceive High-Dynamic Real-World Streams?

Yuxuan Hu, Weikang Shi, Yang Bo وآخرون · 2026

Streaming Video Large Language Models (VLMs) enable continuous video understanding, yet existing benchmarks focus on low-dynamic scenarios. Under bounded context budgets, models must balance temporal history, spatial resolution, and temporal granularity; sparse sampling at 1--2 FPS misses fast events. We introduce Fast …

CARE: Certifying Acceleration for Vision-Language-Action Inference

Rui Liu, Tong Zheng, Jindong Gu وآخرون · 2026

While vision-language-action (VLA) models have advanced rapidly, running them at every control step remains expensive. Prior work accelerates VLA inference using techniques like action chunking and visual-token pruning, typically evaluating based on latency and average task success. However, acceleration may discard in …

D-Loop: Looped Diffusion Drafting for Speculative Decoding

Kecheng Chen, Yuyang He, Cheng Gong وآخرون · 2026

Block diffusion accelerates speculative decoding by drafting multiple tokens in one forward pass. However, each position predicts a marginal distribution without observing earlier proposed tokens, limiting draft quality and acceptance length. We identify a concrete failure, the \emph{repetition trap}, in which neighbor …

Align Then Reason: A Multimodal Lip-Sync Judge for Dubbing

Rui Liu, Bhavin Jawade, Haoqi Li وآخرون · 2026

Dubbing quality control requires a reference-free judge that can determine whether a candidate text line matches a speaker's visible articulation in both content and timing, using only silent video and text because dubbed audio may not yet exist. Existing visual speech recognizers and video-language models are poorly s …

Decoupled and Distilled: Task-Adaptive LoRA-Teachers with Ensemble Knowledge Transfer for Few-Shot Class-Incremental Learning

Hongwei Zhao, Rui Liu, Yansong Liu وآخرون · 2026 · 10.1016/j.neucom.2026.135200

Few-Shot Class-Incremental Learning (FSCIL) addresses the challenge of learning new classes from very limited samples while retaining knowledge of previously learned ones. Although parameter-efficient fine-tuning methods with pre-trained models show promise for class-incremental learning, strict gradient-based constrai …

Dynamic LoRA-Experts and Prototype-Ensemble Matching for Class-Incremental Learning

Hongwei Zhao, Rui Liu, Yansong Liu · 2026 · 10.3390/app16126153

Class-Incremental Learning (CIL) aims to continuously learn new classes without forgetting previously acquired knowledge. Parameter-efficient fine-tuning with pre-trained models reduces parameter overhead but can suffer from cumulative interference and suboptimal alignment between inference samples and specialized modu …

HiTS-CL: A Continual Learning Framework for Long-Horizon Temporal Knowledge Graph Extrapolation

Yansong Liu, Rui Liu, Yuan Zuo وآخرون · 2026

Extrapolative temporal knowledge graph reasoning (TKGR) predicts future facts from historical snapshots. Most existing methods train once on an early prefix of the timeline and then use a frozen model for all future timestamps. We argue that this fixed-prefix protocol is misaligned with extrapolation. It learns from a …

Visual Parallel Search: Learning to Search High-Resolution Images with Parallel Tile Inspection and Adaptive Zoom

Xijia Tao, Yihua Teng, Xinyu Fu وآخرون · 2026

High-resolution visual question answering often fails because a multimodal model does not acquire the small, spatially localized evidence needed to answer a question. Sequential zooming can recover detail, but it asks the main model to choose a region before obtaining a reliable overview. We introduce VPS, a visual par …

How Should Diffusion Language Models Edit Code?

Xijia Tao, Ziru Liu, Shansan Gong وآخرون · 2026

Code editing requires a model to decide where to make changes, generate the new content, and preserve everything else. We study how masked diffusion language models divide these responsibilities across four editing interfaces: whole-file rewriting, search-and-replace, locate-then-infill, and token-level editing. Experi …

SAGE: A Statistical Acceptance Gate for Self-Evolving Agents

Yihao Wang, Linhan Xia, Rui Liu وآخرون · 2026

Large Language Model (LLM)-based agents increasingly self-evolve by editing a persistent skill document that encodes their workflow, tool-use rules, and decision logic. This loop has two steps, an optimizer that proposes a candidate edit and a gate that accepts or rejects it. Prior work has concentrated on the optimize …

ManiEdit: Sequential Unstructured Knowledge Editing for Language Models from a Manifold Perspective

Rui Liu, Chenheng Zhang, Haoxuan Li وآخرون · 2026

Large language models (LLMs) inevitably generate some incorrect or outdated content, necessitating efficient and precise mechanisms for continual knowledge updates. However, existing model editing methods struggle to sequentially edit unstructured long-form knowledge, suffering from severe edit forgetting and degradati …
