RAGEN-2: Reasoning Collapse in Agentic RL

arXiv Apr 7, 2026
RL training of multi-turn LLM agents is inherently unstable, and reasoning quality directly determines task performance. Entropy is widely used to track reasoning stability. However, entropy only measures diversity within the same input, and cannot t... read more

Structural Regularities of Cinema SDR-to-HDR Mapping in a Controlled Mastering Workflow: A Pixel-wise Case Study on ASC StEM2

arXiv Apr 7, 2026
We present an empirical case study of cinema SDR-to-HDR mapping using ASC StEM2, a rare common-source dataset containing EXR scene-referred images and matched SDR/HDR cinema release masters from the same ACES-based mastering workflow. Based on pixel-... read more

Harnessing Hyperbolic Geometry for Harmful Prompt Detection and Sanitization

arXiv Apr 7, 2026
Vision-Language Models (VLMs) have become essential for tasks such as image synthesis, captioning, and retrieval by aligning textual and visual information in a shared embedding space. Yet, this flexibility also makes them vulnerable to malicious pro... read more

Telescope: Learnable Hyperbolic Foveation for Ultra-Long-Range Object Detection

arXiv Apr 7, 2026
Autonomous highway driving, especially for long-haul heavy trucks, requires detecting objects at long ranges beyond 500 meters to satisfy braking distance requirements at high speeds. At long distances, vehicles and other critical objects occupy only... read more

Occlusion Handling by Pushing for Enhanced Fruit Detection

arXiv Apr 7, 2026
In agricultural robotics, effective observation and localization of fruits present challenges due to occlusions caused by other parts of the tree, such as branches and leaves. These occlusions can result in false fruit localization or impede the robo... read more

Evidence-Based Actor-Verifier Reasoning for Echocardiographic Agents

arXiv Apr 7, 2026
Echocardiography plays an important role in the screening and diagnosis of cardiovascular diseases. However, automated intelligent analysis of echocardiographic data remains challenging due to complex cardiac dynamics and strong view heterogeneity. I... read more

DietDelta: A Vision-Language Approach for Dietary Assessment via Before-and-After Images

arXiv Apr 7, 2026
Accurate dietary assessment is critical for precision nutrition, yet most image-based methods rely on a single pre-consumption image and provide only coarse, meal-level estimates. These approaches cannot determine what was actually consumed and often... read more

MorphDistill: Distilling Unified Morphological Knowledge from Pathology Foundation Models for Colorectal Cancer Survival Prediction

arXiv Apr 7, 2026
Background: Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide. Accurate survival prediction is essential for treatment stratification, yet existing pathology foundation models often overlook organ-specific features... read more

Toward a universal foundation model for graph-structured data

arXiv Apr 7, 2026
Graphs are a central representation in biomedical research, capturing molecular interaction networks, gene regulatory circuits, cell--cell communication maps, and knowledge graphs. Despite their importance, currently there is not a broadly reusable f... read more

ODE-free Neural Flow Matching for One-Step Generative Modeling

arXiv Apr 7, 2026
Diffusion and flow matching models generate samples by learning time-dependent vector fields whose integration transports noise to data, requiring tens to hundreds of network evaluations at inference. We instead learn the transport map directly. We p... read more
