Diagnose, Recover, Certify: Task Readiness under Hidden Dynamics Changes
Nguyen Viet Tuan Kiet, Huynh Thi Thanh Binh
A deployed control policy can conceal consequential dynamics changes: an actuator may lose effectiveness without affecting the current task when the policy rarely excites it, despi…
Multi-View Relational Distillation for Spatial Reasoning with Vision-Language Models
Kiet T. Nguyen, Hanbo Shim, Jinwoo Kim +1
Vision-language models (VLMs) have achieved strong image and video understanding, yet their visual-spatial representations remain geometrically fragile, leading to failures in spat…
Back to the Beginning of Heuristic Design: Bridging Code and Knowledge with LLMs
Nguyen Viet Tuan Kiet, Bui Dinh Pham, Dao Van Tung +2
Large language models (LLMs) have recently advanced automatic heuristic design (AHD) for combinatorial optimization (CO), where candidate heuristics are iteratively proposed, evalu…
Universal Few-Shot Spatial Control for Diffusion Models
Kiet T. Nguyen, Chanhyuk Lee, Donggyun Kim +2
Spatial conditioning in pretrained text-to-image diffusion models has significantly improved fine-grained control over the structure of generated images. However, existing control…
