3D-GRAND: A Million-Scale Dataset for 3D-LLMs with Better Grounding and Less Hallucination

CVPR 2025poster

The integration of language and 3D perception is crucial for embodied agents and robots that comprehend and interact with the physical world. While large language models (LLMs) have demonstrated impressive language understanding and generation capabilities, their adaptation to 3D environments (3D-LL…

LLM-Grounder: Open-Vocabulary 3D Visual Grounding with Large Language Model as an Agent

ICRA 2024poster

3D visual grounding is a critical skill for household robots, enabling them to navigate, manipulate objects, and answer questions based on their environment. While existing approaches often rely on extensive labeled data or exhibit limitations in handling complex language queries, we propose LLM-Gro…

Characterizing Internal Evasion Attacks in Federated Learning

AISTATS 2023poster

Federated learning allows for clients in a distributed system to jointly train a machine learning model. However, clients’ models are vulnerable to attacks during the training and testing phases. In this paper, we address the issue of adversarial clients performing “internal evasion attacks”: crafti…
