Method for generating training data to be used for training machine learning model and training data generating device using the same

Abstract

There is provided a method for generating training data for training a machine learning model by a training data generating device, comprising: (a) in response to acquiring an original image, performing sub-processes of: generating an image caption for the original image, extracting at least one noun phrase from the image caption, and performing an open vocabulary object detection on the original image, to thereby generate at least one first pseudo label and performing sub-processes of: extracting at least one proposal from the original image, generating at least one region description, and generating at least one second pseudo label; and (b) filtering the at least one first pseudo label and the at least one second pseudo label according to a preset filtering condition, to thereby generate at least one integrated pseudo label, and generating the training data by annotating the original image with the at least one integrated pseudo label.
