Bottom-Up Skill Discovery from Unsegmented Demonstrations for Long-Horizon Robot Manipulation [article]

Yifeng Zhu, Peter Stone, Yuke Zhu
2022 arXiv   pre-print
Finally, we train a meta controller to compose these skills to solve long-horizon manipulation tasks.  ...  We tackle real-world long-horizon robot manipulation tasks through skill discovery.  ...  In contrast, BUDS breaks down a long-horizon task with skill abstraction, leading to a consistent high performance across tasks of varying lengths.  ...

Unified Simulation, Perception, and Generation of Human Behavior [article]

Ye Yuan
2022 arXiv   pre-print
In this thesis, we take a holistic approach to human behavior modeling and tackle its three essential aspects -- simulation, perception, and generation.  ...  We also discuss the lessons learned and our vision for what is next for human behavior modeling.  ...  Instead of guiding the humanoid using manually-designed tasks or direct user input, our goal is to let the humanoid learn long-term behaviors directly from data.  ...

Prognosis of anterior cruciate ligament reconstruction: a data-driven approach

A. Chandra, O. Kar, K.-C. Wu, M. Hall, J. Gillette
2015 Proceedings of the Royal Society A  
The DDP algorithm facilitates hierarchical handling of the large data set, and can assess the state of recovery in post ACLR conditions based on data collected from stair ascent and descent exercises of  ...  Individuals who suffer anterior cruciate ligament (ACL) injury are at higher risk of developing knee osteoarthritis (OA) and almost 50% display symptoms 10 to 20 years post injury.  ...  A relatively high energy exchange amplitude to achieve the same stair ascent or descent task may be taken as an indication that the individual's knee is 'working hard' to achieve the same task.  ...

Learning Time-Varying Graphs from Online Data [article]

Alberto Natali, Elvin Isufi, Mario Coutino, Geert Leus
2021 arXiv   pre-print
This work proposes an algorithmic framework to learn time-varying graphs from online data.  ...  The generality offered by the framework renders it model-independent, i.e., it can be theoretically analyzed in its abstract formulation and then instantiated under a variety of model-dependent graph learning  ...  Differently from these works, our goal here is to provide a general (model-independent) algorithmic framework for timevarying GTI from online data that can be specialized to a variety of static graph learning  ...
