Dimension-Free Minimax Rates for Learning Pairwise Interactions in Attention-Style Models

ICLR 2026poster

We study the convergence rate of learning pairwise interactions in single-layer attention-style models, where tokens interact through a weight matrix and a non-linear activation function. We prove that the minimax rate is $M^{-\frac{2\beta}{2\beta+1}}$ with $M$ being the sample size, depending only…

From Demand to Grounded Plan: Task Customization and Planning for Service Robots With Deep Learning and LLMs

RA-L 2025

In the field of task planning for service robots, large language model (LLM)-based approaches have shown increasing potential but still struggle with responding to complex user demands and grounded task planning. In this letter, we propose a user-demand-oriented adaptive grounded task planning syste

Nonlocal Attention Operator: Materializing Hidden Knowledge Towards Interpretable Physics Discovery

NeurIPS 2024spotlight

Despite recent popularity of attention-based neural architectures in core AI fields like natural language processing (NLP) and computer vision (CV), their potential in modeling complex physical systems remains under-explored. Learning problems in physical systems are often characterized as discoveri…
