Multi-Agent Cooperative Learning for Robust Vision-Language Alignment under OOD Concepts

Philip Xu

This paper introduces a novel Multi-Agent Cooperative Learning (MACL) framework to address cross-modal alignment collapse in vision-language models when handling out-of-distributio…

A Three-Level Alignment Framework for Large-Scale 3D Retrieval and Controlled 4D Generation

Philip Xu

We introduce Uni4D, a unified framework for large scale open vocabulary 3D retrieval and controlled 4D generation based on structured three level alignment across text, 3D models,…

A Simple yet Effective Test-Time Adaptation for Zero-Shot Monocular Metric Depth Estimation

Rémi Marsal, Alexandre Chapoutot, Philippe Xu +1

The recent development of \emph{foundation models} for monocular depth estimation such as Depth Anything paved the way to zero-shot monocular depth estimation. Since it returns an…

Can LLMs Translate Human Instructions into a Reinforcement Learning Agent's Internal Emergent Symbolic Representation?

Ziqi Ma, Sao Mai Nguyen, Philippe Xu

Emergent symbolic representations are critical for enabling developmental learning agents to plan and generalize across tasks. In this work, we investigate whether large language m…
