Abstract: Provided are a data reduction method and a data processing device. The data processing device includes a memory configured to store target data expressed as a vector matrix and instructions for performing control over data reduction and a processor configured to determine low-rank matrices W1 and W2 from which a target parameter matrix W is constructable. The target parameter matrix W is constructed as the Hadamard product between the low-rank matrices W1 and W2.

Abstract: There is provided a method for generating image change data to be performed by an image change data generating apparatus, the method comprising, inputting an initial image and data parameters to a data generator, generating a first image and a second image respectively, within a first time interval by using the data generator based on the initial image and the data parameters, the first image and the second image being in a relationship of consecutive frames with each other, and generating a first image change data by using a pre-trained first proxy network and a second image change data by using a pre-trained second proxy network based on the first image and the second image.
