ProgVLA: Progress-Aware Robot Manipulation Skill Learning

Seungsu Kim, Jinyoung Choi, Seungmin Baek +1

We present ProgVLA, a compact vision-language-action (VLA) model designed for reliable robot manipulation under tight compute and memory budgets. The model specifically focuses on…

Behavioral Mode Discovery for Fine-tuning Multimodal Generative Policies

Alberta Longhini, David Emukpere, Jean-Michel Renders +1

We address the problem of fine-tuning pre-trained generative policies with reinforcement learning (RL) while preserving the multimodality of their action distributions. Existing me…

Robust Skills, Brittle Grounding: Diagnosing Restricted Generalization in Vision-Language Action Policies via Multi-Object Picking

David Emukpere, Romain Deffayet, Jean-Michel Renders

Vision-language action (VLA) policies often report strong manipulation benchmark performance with relatively few demonstrations, but it remains unclear whether this reflects robust…

Disentangled Object-Centric Image Representation for Robotic Manipulation

David Emukpere, Romain Deffayet, Bingbing Wu +6

Learning robotic manipulation skills from vision is a promising approach for developing robotics applications that can generalize broadly to real-world scenarios. As such, many app…

Unbiased Learning to Rank Meets Reality: Lessons from Baidu's Large-Scale Search Dataset

Philipp Hager, Romain Deffayet, Jean-Michel Renders +2

Unbiased learning-to-rank (ULTR) is a well-established framework for learning from user clicks, which are often biased by the ranker collecting the data. While theoretically justif…

SLIM: Skill Learning with Multiple Critics

David Emukpere, Bingbing Wu, Julien Perez +1

Self-supervised skill learning aims to acquire useful behaviors that leverage the underlying dynamics of the environment. Latent variable models, based on mutual information maximi…
