📄 一、arXiv 最新论文
1. Bidirectional Cross-Modal Prompting for Event-Frame Asymmetric Stereo
- 方向：arXiv/CV
- 摘要：Conventional frame-based cameras capture rich contextual information but suffer from limited temporal resolution and motion blur in dynamic scenes. Event cameras offer an alternative visual representation with higher dynamic range free from such limitations. The complementary characteristics of the two modalities make event-frame asymmetric stereo promising for reliable 3D perception under fast mo…

2. LeapAlign: Post-Training Flow Matching Models at Any Generation Step by Building Two-Step Trajectories
- 方向：arXiv/CV
- 摘要：This paper focuses on the alignment of flow matching models with human preferences. A promising way is fine-tuning by directly backpropagating reward gradients through the differentiable generation process of flow matching. However, backpropagating through long trajectories results in prohibitive memory costs and gradient explosion. Therefore, direct-gradient methods struggle to update early gener…

3. Generalization in LLM Problem Solving: The Case of the Shortest Path
- 方向：arXiv/LG
- 摘要：Whether language models can systematically generalize remains actively debated. Yet empirical performance is jointly shaped by multiple factors such as training data, training paradigms, and inference-time strategies, making failures difficult to interpret. We introduce a controlled synthetic environment based on shortest-path planning, a canonical composable sequential optimization problem. The s…

4. Diagnosing LLM Judge Reliability: Conformal Prediction Sets and Transitivity Violations
- 方向：arXiv/LG
- 摘要：LLM-as-judge frameworks are increasingly used for automatic NLG evaluation, yet their per-instance reliability remains poorly understood. We present a two-pronged diagnostic toolkit applied to SummEval: $\textbf{(1)}$ a transitivity analysis that reveals widespread per-input inconsistency masked by low aggregate violation rates ($\barρ = 0.8$-$4.1%$), with $33$-$67%$ of documents exhibiting at l…

5. MM-WebAgent: A Hierarchical Multimodal Web Agent for Webpage Generation
- 方向：arXiv/AI
- 摘要：The rapid progress of Artificial Intelligence Generated Content (AIGC) tools enables images, videos, and visualizations to be created on demand for webpage design, offering a flexible and increasingly adopted paradigm for modern UI/UX. However, directly integrating such tools into automated webpage generation often leads to style inconsistency and poor global coherence, as elements are generated i…

6. How Do LLMs and VLMs Understand Viewpoint Rotation Without Vision? An Interpretability Study
- 方向：arXiv/AI
- 摘要：Over the past year, spatial intelligence has drawn increasing attention. Many prior works study it from the perspective of visual-spatial intelligence, where models have access to visuospatial information from visual inputs. However, in the absence of visual information, whether linguistic intelligence alone is sufficient to endow models with spatial intelligence, and how models perform relevant t…

7. CoopEval: Benchmarking Cooperation-Sustaining Mechanisms and LLM Agents in Social Dilemmas
- 方向：arXiv/CL
- 摘要：It is increasingly important that LLM agents interact effectively and safely with other goal-pursuing agents, yet, recent works report the opposite trend: LLMs with stronger reasoning capabilities behave less cooperatively in mixed-motive games such as the prisoner’s dilemma and public goods settings. Indeed, our experiments show that recent models – with or without reasoning enabled – consist…

8. From Tokens to Steps: Verification-Aware Speculative Decoding for Efficient Multi-Step Reasoning
- 方向：arXiv/CL
- 摘要：Speculative decoding (SD) accelerates large language model inference by allowing a lightweight draft model to propose outputs that a stronger target model verifies. However, its token-centric nature allows erroneous steps to propagate. Prior approaches mitigate this using external reward models, but incur additional latency, computational overhead, and limit generalizability. We propose SpecGuard,…
