Evaluating Semantic Variation in Text-to-Image Synthesis: A Causal Perspective

ICLR 2025poster

Accurate interpretation and visualization of human instructions are crucial for text-to-image (T2I) synthesis. However, current models struggle to capture semantic variations from word order changes, and existing evaluations, relying on indirect metrics like text-image similarity, fail to reliably…

Multi-Task Domain Adaptation for Language Grounding with 3D Objects

ECCV 2024poster

"The existing works on object-level language grounding with 3D objects mostly focus on improving performance by utilizing the off-the-shelf pre-trained models to capture features, such as viewpoint selection or geometric priors. However, they have failed to consider exploring the cross-modal represe…

Human-in-the-loop Robotic Grasping Using BERT Scene Representation

COLING 2022main

Current NLP techniques have been greatly applied in different domains. In this paper, we propose a human-in-the-loop framework for robotic grasping in cluttered scenes, investigating a language interface to the grasping process, which allows the user to intervene by natural language commands. This f…
