ExACT: An End-to-End Autonomous Excavator System Using Action Chunking With Transformers

no code implementations9 May 2024 Liangliang Chen, Shiyu Jin, Haoyu Wang, Liangjun Zhang

Excavators are crucial for diverse tasks such as construction and mining, while autonomous excavator systems enhance safety and efficiency, address labor shortages, and improve human working conditions.

RLingua: Improving Reinforcement Learning Sample Efficiency in Robotic Manipulations With Large Language Models

no code implementations11 Mar 2024 Liangliang Chen, Yutian Lei, Shiyu Jin, Ying Zhang, Liangjun Zhang

In this paper, we propose RLingua, a framework that can leverage the internal knowledge of large language models (LLMs) to reduce the sample complexity of RL in robotic manipulations.

Dual-Scale Interest Extraction Framework with Self-Supervision for Sequential Recommendation

no code implementations16 Oct 2023 Liangliang Chen, Hongzhan Lin, Jinshan Ma, Guang Chen

Nevertheless, the existing approaches just extract each interest independently for the corresponding sub-sequence while ignoring the global correlation of the entire interaction sequence, which may fail to capture the user's inherent preference for the potential interests generalization and unavoidably make the recommended items homogeneous with the historical behaviors.
