ARLArena: Demystifying Policy Gradient Stability in Agentic Reinforcement Learning

ICML 2026poster

Agentic reinforcement learning (ARL) has rapidly gained attention as a promising paradigm for training agents to solve complex, multi-step interactive tasks. In this paper, we first propose $\textbf{ARLArena}$, a fair and systematic analysis framework that encompasses a broad spectrum of ARL algorit…

Symmetry-Preserving Conformer Ensemble Networks for Molecular Representation Learning

NeurIPS 2025poster

Molecular representation learning has emerged as a promising approach for modeling molecules with deep learning in chemistry and beyond. While 3D geometric models effectively capture molecular structure, they typically process single static conformers, overlooking the inherent flexibility and dynami…

Time-IMM: A Dataset and Benchmark for Irregular Multimodal Multivariate Time Series

NeurIPS 2025poster

Time series data in real-world applications such as healthcare, climate modeling, and finance are often irregular, multimodal, and messy, with varying sampling rates, asynchronous modalities, and pervasive missingness. However, existing benchmarks typically assume clean, regularly sampled, unimodal…
