Sparse Variational Student-t Processes for Heavy-tailed Modeling

arXiv:2408.06699v2 Announce Type: replace Abstract: The Gaussian process (GP) is a powerful tool for nonparametric modeling, but its sensitivity to outliers limits its applicability to data distributions with heavy-tails. Studentt processes offer a robust alternative for heavy tail modeling, but…

SATURN: SAT-based Reinforcement Learning to Unleash LLMs Reasoning

arXiv:2505.16368v4 Announce Type: replace Abstract: How to design reinforcement learning (RL) tasks that effectively unleash the reasoning capability of large language models (LLMs) remains an open question. Existing RL tasks (e.g., math, programming, and constructing reasoning tasks) suffer from three…

Dynamic Multi-period Experts for Online Time Series Forecasting

arXiv:2603.09062v1 Announce Type: new Abstract: Online Time Series Forecasting (OTSF) requires models to continuously adapt to concept drift. However, existing methods often treat concept drift as a monolithic phenomenon. To address this limitation, we first redefine concept drift by categorizing…

Multimodal LLM-assisted Evolutionary Search for Programmatic Control Policies

arXiv:2508.05433v3 Announce Type: replace Abstract: Deep reinforcement learning has achieved impressive success in control tasks. However, its policies, represented as opaque neural networks, are often difficult for humans to understand, verify, and debug, which undermines trust and hinders real-world deployment.…
