DRIM: Depth Restoration with Interference Mitigation in Multiple LiDAR Depth Cameras

ICRA 2026poster

LiDAR depth cameras are widely used for accurate depth measurement in various applications. However, when multiple cameras operate simultaneously, mutual interference causes artifacts in the captured depth data, which existing image restoration methods struggle to handle. In this paper, we propose D…

Enhancing Control Policy Smoothness by Aligning Actions with Predictions from Preceding States

AAAI 2026technical

Deep reinforcement learning has proven to be a powerful approach to solving control tasks, but its characteristic high‑frequency oscillations make it difficult to apply in real‑world environments. While prior methods have addressed action oscillations via architectural or loss-based methods, the lat

Keep it SymPL: Symbolic Projective Layout for Allocentric Spatial Reasoning in Vision-Language Models

CVPR 2026

Perspective-aware spatial reasoning involves understanding spatial relationships from specific viewpoints--either egocentric (observer-centered) or allocentric (object-centered).While vision-language models (VLMs) perform well in egocentric settings, their performance deteriorates when reasoning fro

SiNGER: A Clearer Voice Distills Vision Transformers Further

ICLR 2026poster

Vision Transformers are widely adopted as the backbone of vision foundation models, but they are known to produce high-norm artifacts that degrade representation quality. When knowledge distillation transfers these features to students, high-norm artifacts dominate the objective, so students overfit…

Squeezing the Last Drop of Accuracy: Hand-Eye Calibration Via Deep Reinforcement Learning-Guided Pose Tuning

ICRA 2026poster

Hand-eye calibration is a fundamental task in robotics, requiring high precision to ensure accurate manipulation. This is especially crucial for recent markerless methods, which depend on precise pose estimation for effective end-effector calibration. In this paper, we propose a novel approach that …

Stabilizing the Q-Gradient Field for Policy Smoothness in Actor-Critic Methods

ICML 2026oral

Policies learned via continuous actor-critic methods often exhibit erratic, high-frequency oscillations, making them unsuitable for physical deployment. Current approaches attempt to enforce smoothness by directly regularizing the policy's output. We argue that this approach treats the symptom rathe…
