Enhancing Agentic Search via Data Synthesis on Hierarchical Constraint Satisfaction

ICLR 2026poster

Deep research becomes increasingly important as people seek to solve complex problems that require gathering and synthesizing information from diverse sources. A key capability in this process is agentic search, where an LLM-agent iteratively retrieves relevant information across multiple sources wh…

OmniGen2: Towards Instruction-Aligned Multimodal Generation

CVPR 2026

Multimodal generative models can process instructions in various modalities and demonstrate outstanding performance across a wide range of image generation tasks. However, their robustness in complex real-world scenarios remains limited due to insufficient generalized instruction alignment. We intro

SFCo-Nav: Efficient Zero-Shot Visual Language Navigation Via Collaboration of Slow LLM and Fast Attributed Graph Alignment

ICRA 2026poster

Recent advances in large vision-language models (VLMs) and large language models (LLMs) have enabled zero-shot approaches to Visual Language Navigation (VLN), where an agent follows natural language instructions using only ego perception and reasoning. However, existing zero‑shot methods typically c…

FinRL-Meta: Market Environments and Benchmarks for Data-Driven Financial Reinforcement Learning

NeurIPS 2022accept

Finance is a particularly challenging playground for deep reinforcement learning. However, establishing high-quality market environments and benchmarks for financial reinforcement learning is challenging due to three major factors, namely, low signal-to-noise ratio of financial data, survivorship bi…
