DeCo: Task Decomposition and Skill Composition for Zero-Shot Generalization in Long-Horizon 3D Manipulation

RA-L 2026

Generalizing language-conditioned multi-task imitation learning (IL) models to novel long-horizon 3D manipulation tasks is challenging. To address this, we propose <bold xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">DeCo</b> (<italic xmlns:mml="http://www.

A Self-Evolving Framework for Multi-Agent Medical Consultation Based on Large Language Models

ICASSP 2025accepted

We propose a multi-agent approach (SeM-Agents) based on large language models for medical consultations. This framework incorporates various doctor roles and auxiliary roles, with agents communicating through natural language. Using a residual structure, the system conducts multi-round medical consu…

Exploiting the Relationship within the Unlabelled Samples by Set Matching for Generalized Category Discovery

ICASSP 2025accepted

Generalized Category Discovery (GCD) is an open-world problem in semi-supervised learning, where the model leverages labelled data from known classes to discover both known and unknown classes in unlabelled data. Contrastive learning is key to this process, helping generate discriminative features t…

GravMAD: Grounded Spatial Value Maps Guided Action Diffusion for Generalized 3D Manipulation

ICLR 2025poster

Robots' ability to follow language instructions and execute diverse 3D manipulation tasks is vital in robot learning. Traditional imitation learning-based methods perform well on seen tasks but struggle with novel, unseen ones due to variability. Recent approaches leverage large foundation models to…

An Efficient Deep Reinforcement Learning Algorithm for Solving Imperfect Information Extensive-Form Games

AAAI 2023technical

One of the most popular methods for learning Nash equilibrium (NE) in large-scale imperfect information extensive-form games (IIEFGs) is the neural variants of counterfactual regret minimization (CFR). CFR is a special case of Follow-The-Regularized-Leader (FTRL). At each iteration, the neural varia…

Consistent MetaReg: Alleviating Intra-task Discrepancy for Better Meta-knowledge

IJCAI 2020poster

In the few-shot learning scenario, the data-distribution discrepancy between training data and test data in a task usually exists due to the limited data. However, most existing meta-learning approaches seldom consider this intra-task discrepancy in the meta-training phase which might deteriorate th…

A Novel Image-Specific Transfer Approach for Prostate Segmentation in MR Images

ICASSP 2018accepted

Prostate segmentation in Magnetic Resonance (MR) Images is a significant yet challenging task for prostate cancer treatment. Most of the existing works attempted to design a global classifier for all MR images, which neglect the discrepancy of images across different patients. To this end, we propos…
