Display apparatus and control method therefor

Abstract

A display apparatus, includes: a memory configured to store at least one instruction; and one or more processors configured to execute the at least one instruction to cause the display apparatus to: obtain weight value information for clusters classified according to picture quality by inputting an input image in a prediction neural network model; obtain an adaptive neural network model by respectively applying the weight value information to neural network models corresponding to the clusters; and obtain an output image with improved picture quality by inputting the input image in the adaptive neural network model, wherein the prediction neural network model is a model trained to output probability values for the clusters based on loss information for output images obtained by inputting learning images into the neural network models.
