LIBERO is a lifelong learning benchmark in robot manipulation that focuses on knowledge transfer in declarative and procedural domains. It introduces five key research areas in lifelong learning for decision-making (LLDM) and offers a procedural task generation pipeline with 130 tasks. Experiments reveal the superiority of sequential fine-tuning over existing LLDM methods. The benchmark includes high-quality human-teleoperated demonstration data for all tasks. It aims to investigate essential LLDM research areas, such as knowledge transfer, neural architecture design, algorithm design, task order robustness, and pre-trained model utilization.
Introducing LIBERO: A Lifelong Robot Learning Benchmark for Decision-Making and Robotics
Researchers from the University of Texas at Austin, Sony AI, and Tsinghua University have developed LIBERO, a benchmark that focuses on lifelong learning in decision-making for robot manipulation. Unlike previous studies that primarily focused on transferring declarative knowledge, LIBERO explores transferring both declarative and procedural knowledge. It offers a procedural task generation pipeline and high-quality human-teleoperated data. LIBERO investigates key research areas such as knowledge transfer, neural architecture design, algorithm design, task order robustness, and pre-trained model utilization.
Practical Solutions and Value
