Latent Reasoning VLA: Latent Thinking and Prediction for Vision-Language-Action Models

ICML 2026poster

Vision-Language-Action (VLA) models benefit from Chain-of-Thought (CoT) reasoning, but existing approaches incur high inference overhead and rely on discrete reasoning representations that mismatch continuous perception and control. We propose Latent Reasoning VLA (LaRA-VLA), a unified VLA framework…

Trusted Multi-view Learning for Long-tailed Classification

AAAI 2026technical

Class imbalance has been extensively studied in single-view scenarios; however, addressing this challenge in multi-view contexts remains an open problem, with even scarcer research focusing on trustworthy solutions. In this paper, we tackle a particularly challenging class imbalance problem in multi

In-context Vectors: Making In Context Learning More Effective and Controllable Through Latent Space Steering

ICML 2024poster

Large language models (LLMs) demonstrate emergent in-context learning capabilities, where they adapt to new tasks based on example demonstrations. However, in-context learning has seen limited effectiveness in many settings, is difficult to quantitatively control and takes up context window space. T…

L2B: Learning to Bootstrap Robust Models for Combating Label Noise

CVPR 2024poster

Deep neural networks have shown great success in representation learning. Deep neural networks have shown great success in representation learning. However when learning with noisy labels (LNL) they can easily overfit and fail to generalize to new data. This paper introduces a simple and effective m…

Solving Inverse Problems in Medical Imaging with Score-Based Generative Models

ICLR 2022poster

Reconstructing medical images from partial measurements is an important inverse problem in Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). Existing solutions based on machine learning typically train a model to directly map measurements to medical images, leveraging a training dataset…
