摘要:

人体运动预测是实现更紧密的人机协作的重要组成部分。准确预测人体运动的任务是不平凡的。它是由人类运动的可变性,在骨骼水平,由于人类的不同大小和在运动水平,由于个人运动的特质。这些变量使得学习算法获得对人类运动的不同时空模式鲁棒的一般表示具有挑战性。在这项工作中,我们提出了一种模块化的序列学习方法,允许端到端的训练,同时也具有微调的灵活性。我们的方法依赖于训练样本的多样性,首先学习一个鲁棒的表示,然后可以在持续学习设置中进行微调,以预测新对象的运动。我们通过比较其性能与最先进的基线来评估所提出的方法。结果表明,我们的方法在所有评估的时间范围内都优于其他方法,只需使用少量数据进行微调。我们的方法的改进性能开辟了使用持续学习进行个性化和可靠的运动预测的可能性。

英文摘要:

Human motion prediction is an essential component for enabling closer human-robot collaboration. The task of accurately predicting human motion is non-trivial. It is compounded by the variability of human motion, both at a skeletal level due to the varying size of humans and at a motion level due to individual movement's idiosyncrasies. These variables make it challenging for learning algorithms to obtain a general representation that is robust to the diverse spatio-temporal patterns of human motion. In this work, we propose a modular sequence learning approach that allows end-to-end training while also having the flexibility of being fine-tuned. Our approach relies on the diversity of training samples to first learn a robust representation, which can then be fine-tuned in a continual learning setup to predict the motion of new subjects. We evaluated the proposed approach by comparing its performance against state-of-the-art baselines. The results suggest that our approach outperforms other methods over all the evaluated temporal horizons, using a small amount of data for fine-tuning. The improved performance of our approach opens up the possibility of using continual learning for personalized and reliable motion prediction.
