Reasoning Paths with Reference Objects Elicit Quantitative Spatial Reasoning in Large Vision-Language Models

no code implementations15 Sep 2024 Yuan-Hong Liao, Rafid Mahmood, Sanja Fidler, David Acuna

Inspired by this observation, we develop a zero-shot prompting technique, SpatialPrompt, that encourages VLMs to answer quantitative spatial questions using reference objects as visual cues.

Can Feedback Enhance Semantic Grounding in Large Vision-Language Models?

no code implementations9 Apr 2024 Yuan-Hong Liao, Rafid Mahmood, Sanja Fidler, David Acuna

We find that if prompted appropriately, VLMs can utilize feedback both in a single step and iteratively, showcasing the potential of feedback as an alternative technique to improve grounding in internet-scale VLMs.

Emergent Road Rules In Multi-Agent Driving Environments

1 code implementation ICLR 2021 Avik Pal, Jonah Philion, Yuan-Hong Liao, Sanja Fidler

For autonomous vehicles to safely share the road with human drivers, autonomous vehicles must abide by specific "road rules" that human drivers have agreed to follow.

Synthesizing Environment-Aware Activities via Activity Sketches

no code implementations CVPR 2019 Yuan-Hong Liao, Xavier Puig, Marko Boben, Antonio Torralba, Sanja Fidler

In order to learn to perform activities from demonstrations or descriptions, agents need to distill what the essence of the given activity is, and how it can be adapted to new environments.

Tactics of Adversarial Attack on Deep Reinforcement Learning Agents

no code implementations8 Mar 2017 Yen-Chen Lin, Zhang-Wei Hong, Yuan-Hong Liao, Meng-Li Shih, Ming-Yu Liu, Min Sun

In the strategically-timed attack, the adversary aims at minimizing the agent's reward by only attacking the agent at a small subset of time steps in an episode.
