Cosmos 3: Omnimodal World Models for Physical AI

NVIDIA, :, Aditi +293

We introduce Cosmos 3, a family of omnimodal world models designed to jointly process and generate language, image, video, audio, and action sequences within a unified mixture-of-t…

Beyond Homophily: Towards Generalized Graph Reconstruction Attack and Defense

Zhanke Zhou, Bo Han, Xuan Li +3

Graph neural networks (GNNs) are widely deployed on relational data, yet they can leak sensitive or proprietary information about the training graph adjacency, e.g., social ties, t…

Deliberate Evolution: Agentic Reasoning for Sample-Efficient Symbolic Regression with LLMs

Xinyu Pang, Zhanke Zhou, Xuan Li +5

Symbolic regression (SR) discovers compact mathematical expressions from data, yet recent LLM-based evolutionary methods remain sample-inefficient because they rely mainly on scala…

Co-rewarding: Stable Self-supervised RL for Eliciting Reasoning in Large Language Models

Zizhuo Zhang, Jianing Zhu, Xinmu Ge +6

While reinforcement learning with verifiable rewards (RLVR) is effective to improve the reasoning ability of large language models (LLMs), its reliance on human-annotated labels le…

AlphaApollo: A System for Deep Agentic Reasoning

Zhanke Zhou, Chentao Cao, Xiao Feng +15

We present AlphaApollo, an agentic reasoning system that targets two bottlenecks in foundation-model reasoning: (1) limited reasoning capacity for complex, long-horizon problem sol…

Reference-guided Policy Optimization for Molecular Optimization via LLM Reasoning

Xuan Li, Zhanke Zhou, Zongze Li +4

Large language models (LLMs) benefit substantially from supervised fine-tuning (SFT) and reinforcement learning with verifiable rewards (RLVR) in reasoning tasks. However, these re…
