摘要:

机器人可以通过适应被操纵对象的特征来概括不同场景之间的操纵技能。选择用于概括技能的相关特征的集合通常由人手动执行。或者,机器人可以学习自主选择相关特征。然而,特征选择通常需要大量的训练数据,这将需要许多演示。为了更有效地学习相关功能,我们建议使用元级别之前,从以前学到的技能转移功能的相关性。实验表明,元级先验比标准的均匀先验的平均精度和召回率的特征选择时,增加了一倍以上。所提出的方法被用来学习各种操作技能,包括推动,切割和倾倒。

英文摘要:

Robots can generalize manipulation skills between different scenarios by adapting to the features of the objects being manipulated. Selecting the set of relevant features for generalizing skills has usually been performed manually by a human. Alternatively, a robot can learn to select relevant features autonomously. However, feature selection usually requires a large amount of training data, which would require many demonstrations. In order to learn the relevant features more efficiently, we propose using a meta-level prior to transfer the relevance of features from previously learned skills. The experiments show that the meta-level prior more than doubles the average precision and recall of the feature selection when compared to a standard uniform prior. The proposed approach was used to learn a variety of manipulation skills, including pushing, cutting, and pouring.
