| 2026 | Forest Before Trees: Latent Superposition for Efficient Visual ReasoningabstractWhile Chain-of-Thought empowers Large Vision-Language Models with multi-step reasoning, explicit textual rationales suffer from an information bandwidth bottleneck, where continuous visual details are discarded during discrete tokenization.Recent latent reasoning methods attempt to address this challenge, but often fall prey to premature semantic collapse due to rigid autoregressive objectives.In this paper, we propose Laser, a novel paradigm that reformulates visual deduction via Dynamic Windowed Alignment Learning(DWAL).Instead of forcing a point-wise prediction, Laser aligns the latent state with a dynamic validity window of future semantics.This mechanism enforces a "Forest-before-Trees" cognitive hierarchy, enabling the model to maintain a probabilistic superposition of global features before narrowing down to local details.Crucially, Laser maintains interpretability via decodable trajectories while stabilizing unconstrained learning via Self-Refined Superposition.Extensive experiments on 6 benchmarks demonstrate that Laser achieves state-of-the-art performance among latent reasoning methods, surpassing the strong baseline Monet by 5.03% on average.Notably, it achieves these gains with extreme efficiency, reducing inference tokens by more than 97%, while demonstrating robust generalization to out-of-distribution domains.We hope this work encourages a paradigm shift from explicit next-token prediction to latent visual reasoning: Laser Juntian Zhang, Nils Lukas, Yuhan Liu 0030 |

| 2025 | Weaving Context Across Images: Improving Vision-Language Models through Focus-Centric Visual ChainsabstractVision-language models (VLMs) achieve remarkable success in single-image tasks.However, real-world scenarios often involve intricate multi-image inputs, leading to a notable performance decline as models struggle to disentangle critical information scattered across complex visual features.In this work, we propose Focus-Centric Visual Chain, a novel paradigm that enhances VLMs' perception, comprehension, and reasoning abilities in multi-image scenarios.To facilitate this paradigm, we propose Focus-Centric Data Synthesis, a scalable bottom-up approach for synthesizing high-quality data with elaborate reasoning paths.Through this approach, We construct VISC-150K, a large-scale dataset with reasoning data in the form of Focus-Centric Visual Chain, specifically designed for multi-image tasks.Experimental results on seven multi-image benchmarks demonstrate that our method achieves average performance gains of 3.16% and 2.24% across two distinct model architectures, without compromising the general vision-language capabilities.Our study represents a significant step toward more robust and capable vision-language systems that can handle complex visual scenarios: VISC. * Corresponding authors.Which of the following images contains the same object as the first image and shares the same attribute weight?

| 2025 | Beyond Static Testbeds: An Interaction-Centric Agent Simulation Platform for Dynamic Recommender SystemsabstractEvaluating and iterating upon recommender systems is crucial, yet traditional A/B testing is resource-intensive, and offline methods struggle with dynamic user-platform interactions.While agent-based simulation is promising, existing platforms often lack a mechanism for user actions to dynamically reshape the environment.To bridge this gap, we introduce RecInter, a novel agent-based simulation platform for recommender systems featuring a robust interaction mechanism.In RecInter platform, simulated user actions (e.g., likes, reviews, purchases) dynamically update item attributes in real-time, and introduced Merchant Agents can reply, fostering a more realistic and evolving ecosystem.High-fidelity simulation is ensured through Multidimensional User Profiling module, Advanced Agent Architecture, and LLM fine-tuned on Chain-of-Thought (CoT) enriched interaction data.Our platform achieves significantly improved simulation credibility and successfully replicates emergent phenomena like Brand Loyalty and the Matthew Effect.Experiments demonstrate that this interaction mechanism is pivotal for simulating realistic system evolution, establishing our platform as a credible testbed for recommender systems research: RecInter.

| 2025 | The Stepwise Deception: Simulating the Evolution from True News to Fake News with LLM AgentsabstractWith the growing spread of misinformation online, understanding how true news evolves into fake news has become crucial for early detection and prevention.However, previous research has often assumed fake news inherently exists rather than exploring its gradual formation.To address this gap, we propose FUSE (Fake news evolUtion Simulation framEwork), a novel Large Language Model (LLM)-based simulation approach explicitly focusing on fake news evolution from real news.Our framework model a social network with four distinct types of LLM agents commonly observed in daily interactions: spreaders who propagate information, commentators who provide interpretations, verifiers who fact-check, and bystanders who observe passively to simulate realistic daily interactions that progressively distort true news.To quantify these gradual distortions, we develop FUSE-EVAL, a comprehensive evaluation framework measuring truth deviation along multiple linguistic and semantic dimensions.Results show that FUSE effectively captures fake news evolution patterns and accurately reproduces known fake news, aligning closely with human evaluations.Experiments demonstrate that FUSE accurately reproduces known fake news evolution scenarios, aligns closely with human judgment, and highlights the importance of timely intervention at early stages.Our framework is extensible, enabling future research on broader scenarios of fake news: FUSE.
