Human2Robot: Learning Robot Actions from Paired Human-Robot Videos

AAAI 2026technical

Distilling knowledge from human demonstrations is a promising way for robots to learn and act. Existing methods, which often rely on coarsely-aligned video pairs, are typically constrained to learning global or task-level features. As a result, they tend to neglect the fine-grained frame-level dynam

Understanding and Improving Length Generalization in Hierarchical Sparse Attention Models

ICLR 2026poster

Effectively processing long contexts is a critical challenge for language models. While standard Transformers are limited by quadratic complexity and poor length extrapolation, alternative architectures like sliding window attention and state space models sacrifice the ability to effectively utilize…

FNIN: A Fourier Neural Operator-based Numerical Integration Network for Surface-from-gradients

AAAI 2025technical

Surface-from-gradients (SfG) aims to recover a three-dimensional (3D) surface from its gradients. Traditional methods encounter significant challenges in achieving high accuracy and handling high-resolution inputs, particularly facing the complex nature of discontinuities and the inefficiencies asso…

Hardware-aligned Hierarchical Sparse Attention for Efficient Long-term Memory Access

NeurIPS 2025poster

A key advantage of Recurrent Neural Networks (RNNs) over Transformers is their linear computational and space complexity enables faster training and inference for long sequences. However, RNNs are fundamentally unable to randomly access historical context, and simply integrating attention mechanisms…

Differentiable Quantum Computing for Large-scale Linear Control

NeurIPS 2024poster

As industrial models and designs grow increasingly complex, the demand for optimal control of large-scale dynamical systems has significantly increased. However, traditional methods for optimal control incur significant overhead as problem dimensions grow. In this paper, we introduce an end-to-end q…

Differentiable Analog Quantum Computing for Optimization and Control

NeurIPS 2022accept

We formulate the first differentiable analog quantum computing framework with specific parameterization design at the analog signal (pulse) level to better exploit near-term quantum devices via variational methods. We further propose a scalable approach to estimate the gradients of quantum dynamics…
