METHOD AND APPARATUS FOR EXTRACTING RESULT INFORMATION USING MACHINE LEARNING

A method of operating a neural network device for extracting result information using machine learning according to an embodiment of the present disclosure includes: extracting feature data from an image frame; storing a pre-trained first training model generated by performing machine learning on the feature data and including first training data; storing a pre-trained second training model that is generated by performing machine learning on the first training data and includes second training data generated according to the four arithmetic operations based on the first training data; and generating two-dimensional vector information on the result information by performing a probability-based operation on the second training data in the image frame based on the second training model.
