Machine Learning 

MLMachine Learning is the field of artificial intelligence that allows computers to make predictions or decisions regarding data without a specific programme instructing them how to do it. ML allows the computer to learn, using statistical methods to train algorithms to improve their output based on sample data. ML is used for extracting features and patterns from data and can therefore be used in the automated analysis of NDT signals and data.
