  • RULE-BASED MACHINE LEARNING CLASSIFIER CREATION AND TRACKING PLATFORM FOR FEEDBACK TEXT ANALYSIS
    Publication number: 20220366138
    Abstract: A system and method for creating a machine learning (ML) classifier for a database uses a weakly-supervised training data set created automatically from database items on the basis of a human-created keyword set. The automatically created training data set is used to construct one or more deep learning classifier checkpoints, which can then be compared with one another and with a classifier based on the original keyword set in order to select a classifier for use by other users viewing the database.
