Machine learning device, classification device, and control device

Abstract

A machine learning device comprises: a video data feature extraction unit that extracts a feature of an action performed by a worker from video data; a training data extraction unit that assigns the video data with a label indicating work details of a specific action to extract training data; an operation data feature extraction unit that extracts a feature relevant to the extracted training data from operation data; a label assignment criteria creation unit that creates label assignment criteria for video data and operation data; a label assignment unit that assigns labels to unlabeled video data and operation data on the basis of the label assignment criterias for video data and operation data; and a training unit that executes machine learning using training data including labelled video data to generate a trained model for classifying work of a worker on the basis of video data.
