HBRB-BoW: A Retrained Bag-Of-Words Vocabulary for ORB-SLAM Via Hierarchical BRB-KMeans

ICRA 2026poster

In visual simultaneous localization and mapping (SLAM), the quality of the visual vocabulary is fundamental to the system's ability to represent environments and recognize locations. While ORB-SLAM is a widely used framework, its binary vocabulary, trained through the k-majority-based bag-of-words (…

Privacy-Preserving Argumentative Explanations (Student Abstract)

AAAI 2026technical

We propose a framework for privacy-preserving argumentative explanations using homomorphic encryption. This method applies the Cheon-Kim-Kim-Song scheme, along with a soft k-means adapted for encrypted computation, to generate explanations without exposing sensitive data. By leveraging GPU accelerat

X-MOS: A Heterogeneous Cross-LiDAR Generalization Framework for Moving Object Segmentation

ICRA 2026poster

Moving object segmentation (MOS) is foundational for autonomous vehicle safety. However, the increasing diversity of LiDAR sensors creates a significant domain shift problem, causing models trained on one sensor to perform poorly when deployed on another. A naive approach of training on combined dat…
