Automation using deep learning from demonstrations requires many training examples. Gathering this data is time consuming and expensive, and human demonstrators are prone to inconsistencies and errors that can delay or degrade learning. This paper explores how characterizing supervisor inconsistency and correcting for this noise can improve task performance with a limited budget of data. We consider a planar part extraction task (separating one part from a group) where human operators provide demonstrations by teleoperating a 2DOF robot. We analyze 30,000 image-control pairs from 480 trajectories. After error corrections, trained CNN models show an improvement of 11.2% upon the baseline in mean absolute success rate.
