Observer-Actor: Active Vision Imitation Learning with Sparse-View Gaussian Splatting

The paper introduces Observer-Actor (ObAct), a novel active vision imitation learning framework for dual-arm robots that dynamically assigns one arm to construct a 3D Gaussian Splatting representation and identify optimal viewing angles for the other arm, thereby significantly enhancing policy robustness and performance by reducing occlusions compared to static-camera setups.

GRAND: Guidance, Rebalancing, and Assignment for Networked Dispatch in Multi-Agent Path Finding

The paper proposes GRAND, a hybrid hierarchical algorithm that combines reinforcement learning-based graph guidance with minimum-cost flow rebalancing and local assignment to achieve up to 10% higher throughput than state-of-the-art schedulers for large-scale, lifelong multi-agent pickup-and-delivery tasks while maintaining real-time execution.

Fairness-Aware Fine-Tuning of Vision-Language Models for Medical Glaucoma Diagnosis

This paper introduces fairness-aware Low-Rank Adaptation methods, specifically FR-LoRA, GR-LoRA, and Hybrid-LoRA, which utilize a differentiable MaxAccGap loss and inverse frequency weighting to significantly reduce diagnostic accuracy disparities in glaucoma detection across demographic groups while maintaining high overall accuracy with minimal trainable parameters.

Guided Flow Policy: Learning from High-Value Actions in Offline Reinforcement Learning

The paper introduces Guided Flow Policy (GFP), a novel offline reinforcement learning method that couples a multi-step flow-matching policy with a distilled one-step actor to selectively focus on high-value actions, achieving state-of-the-art performance across diverse benchmarks by overcoming the limitations of indiscriminate behavior regularization.
