Structural properties of admissible subgraphs and the depth of symbolic powers of cover ideals

Nguyen Thu Hang, Nguyen Thi Thanh Tam, Thanh Vu

Let be a simple graph with cover ideal in a polynomial ring $S = \k[x_1, \ldots, x_n]$. For each integer , let denote the maximum size of an ordered ma…

Humanity's Sixth Sense: Benchmarking Intuitive Visual Reasoning in Multimodal Models

Xingang Guo, Jing Gu, Brian Jang +26

Humans perceive far more in a scene than what is explicitly depicted: a single glance captures past causes and future trajectories; a quick peek determines if a vehicle can fit bet…

SteerDuplex: Steerable Duplex Speech Dialogue Models

Utkarsh Tyagi, Ramaneswaran Selvakumar, Advait Gosai +13

Full-duplex spoken dialogue models support low-latency turn taking, interruption handling, and backchanneling, yet a key capability remains underexplored: steerability, the ability…

Rubric Dropout: A Simple Way to Mitigate Reward Hacking in Rubric-Based RL

Minglai Yang, Xinyu Guo, Zhengliang Shi +8

Rubric-based reinforcement learning, in which an LLM judge scores responses against prompt-specific criteria, has become a standard way to post-train language models on tasks witho…

Rubric-Guided Self-Distillation: Post-Training Without Rubric Verifiers

MohammadHossein Rezaei, Anas Mahmoud, Zihao Wang +6

Rubrics have emerged as an alternative to RLVR in open-ended domains where a single ground-truth final answer is not available. Existing rubric-based training methods rely on an LL…

Not Every Rubric Teaches Equally: Policy-Aware Rubric Rewards for RLVR

Utkarsh Tyagi, Xingang Guo, MohammadHossein Rezaei +5

Reinforcement learning with verifiable rewards has made post-training highly effective when correctness can be checked automatically. However, many important model behaviors requir…

SciPredict: Can LLMs Predict the Outcomes of Scientific Experiments in Natural Sciences?

Udari Madhushani Sehwag, Elaine Lau, Haniyeh Ehsani Oskouie +14

Accelerating scientific discovery requires the identification of which experiments would yield the best outcomes before committing resources to costly physical validation. While ex…

Audio Hallucination Attacks: Probing the Reliability of Large Audio Language Models

Ashish Seth, Sonal Kumar, Ramaneswaran Selvakumar +5

Large Audio Language Models (LALMs) achieve strong performance on audio-language tasks; however, their reliability in real-world settings remains underexplored. We introduce Audio…

Audio MultiChallenge: A Multi-Turn Evaluation of Spoken Dialogue Systems on Natural Human Interaction

Advait Gosai, Tyler Vuong, Utkarsh Tyagi +8

End-to-end (E2E) spoken dialogue systems are increasingly replacing cascaded pipelines for voice-based human-AI interaction, processing raw audio directly without intermediate tran…

Beyond Seeing: Evaluating Multimodal LLMs on Tool-Enabled Image Perception, Transformation, and Reasoning

Xingang Guo, Utkarsh Tyagi, Advait Gosai +8

Multimodal Large Language Models (MLLMs) are increasingly applied in real-world scenarios where user-provided images are often imperfect, requiring active image manipulations such…
