Two-Stage Extrinsic Calibration of a Static Line-Scanning Lidar with a Rotary Platform

Vikram Shree, Hike Danakian, Long Nguyen, Rajanish Gokidi, Patrick Nercessian

A line-scanning lidar yields range and azimuth values in a fixed plane. To perceive surrounding objects in 3D, there must be relative motion between the lidar plane and the object. Thus, using a rotating base-platform is promising for industrial applications where objects need to…

DeLIVeR: Decomposed Learning for Information-grounded Veracity Recognition via Reinforced Knowledge Graph Exploration

Cong Hoan Nguyen, Thomas Hoang, Hieu Minh Duong, Long Nguyen

Automated fact-checking remains a challenge for Large Language Models (LLMs) due to "query brittleness" in traditional retrieval systems. We propose DeLIVeR (Decomposed Learning for Information-grounded Veracity Recognition), a framework that treats evidence retrieval as a reinfo…
