Efficient Skill Grounding via Code Refactoring with Small Language Models

ICML 2026poster

Effective skill grounding is essential for deploying reusable skills in embodied agents, as even minor embodiment or environmental differences can render an entire skill incompatible. This challenge is particularly pronounced in embodied settings, where agents must operate in dynamic, partially obse…

Functional Cache Grafting: Robust and Rapid Code-Policy Synthesis for Embodied Agents

ICML 2026poster

Code-writing large language models (CodeLLMs) generate executable code policies for embodied agents by translating natural language goals and environmental constraints into structured control programs. However, policy generation in open-domain embodied environments suffers from two fundamental limit…

NeSyC: A Neuro-symbolic Continual Learner For Complex Embodied Tasks In Open Domains

ICLR 2025poster

We explore neuro-symbolic approaches to generalize actionable knowledge, enabling embodied agents to tackle complex tasks more effectively in open-domain environments. A key challenge for embodied agents is the generalization of knowledge across diverse environments and situations, as limited experi…

Policy Compatible Skill Incremental Learning via Lazy Learning Interface

NeurIPS 2025spotlight

Skill Incremental Learning (SIL) is the process by which an embodied agent expands and refines its skill set over time by leveraging experience gained through interaction with its environment or by the integration of additional data. SIL facilitates efficient acquisition of hierarchical policies gro…

Towards Reliable Code-as-Policies: A Neuro-Symbolic Framework for Embodied Task Planning

NeurIPS 2025spotlight

Recent advances in large language models (LLMs) have enabled the automatic generation of executable code for task planning and control in embodied agents such as robots, demonstrating the potential of LLM-based embodied intelligence. However, these LLM-based code-as-policies approaches often suffer…

Embodied CoT Distillation From LLM To Off-the-shelf Agents

ICML 2024poster

We address the challenge of utilizing large language models (LLMs) for complex embodied tasks, in the environment where decision-making systems operate timely on capacity-limited, off-the-shelf devices. We present DeDer, a framework for decomposing and distilling the embodied reasoning capabilities…

Incremental Learning of Retrievable Skills For Efficient Continual Task Adaptation

NeurIPS 2024poster

Continual Imitation Learning (CiL) involves extracting and accumulating task knowledge from demonstrations across multiple stages and tasks to achieve a multi-task policy. With recent advancements in foundation models, there has been a growing interest in adapter-based CiL approaches, where adapters…

Efficient Policy Adaptation with Contrastive Prompt Ensemble for Embodied Agents

NeurIPS 2023poster

For embodied reinforcement learning (RL) agents interacting with the environment, it is desirable to have rapid policy adaptation to unseen visual observations, but achieving zero-shot adaptation capability is considered as a challenging problem in the RL context. To address the problem, we present…
