Autonomous Vehicle Path Planning by Searching With Differentiable Simulation

Asen Nachkov, Jan-Nico Zaech, Danda Pani Paudel +2

Planning allows an agent to safely refine its actions before executing them in the real world. In autonomous driving, this is crucial to avoid collisions and navigate in complex, d…

LangHOPS: Language Grounded Hierarchical Open-Vocabulary Part Segmentation

Yang Miao, Jan-Nico Zaech, Xi Wang +3

We propose LangHOPS, the first Multimodal Large Language Model (MLLM) based framework for open-vocabulary object-part instance segmentation. Given an image, LangHOPS can jointly de…
