Abstract: A model learning device determines a first machine learning model so as to further increase a combined loss function obtained by combining: a first loss function indicating the level of change in the reliability of a second image feature in a feature region of a reconstructed image, from the reliability of a first image feature in a feature region of the original image; and a second loss function indicating the level of recognition error. In addition, the model learning device: determines, so as to further reduce the combined loss function, respective parameter sets for a second machine learning model used in the generation of compressed data, and a third machine learning model used in the generation of the reconstructed image from the compressed data; and determines a parameter set for the fourth machine learning model in common with that for the first machine learning model.

Abstract: A parameter set of a first machine learning model is determined such that a first loss function becomes larger. The first loss function indicates a degree of variation from a conditional confidence of a first image feature conditional on a third image feature to a conditional confidence of a second image feature conditional on the third image feature. The third image feature is an image feature for recognition of a subject extracted from an original image. The first image feature is discriminated in a specific region of the original image by using a first machine learning model. A parameter set of each of the second machine learning model and the third machine learning model are determined such that a second loss function becomes smaller.

Abstract: A management method and apparatus which allows easy management of virtual network function deployment on a network are provided. A network management apparatus generates an extended topology in which a virtual network function that can be deployed on a server is added as an extended node ((VNF(A), VNF(B)) to a topology of the network; and displays an optimum path (RP1, RP2, RP3) in the extended topology on display means (400b) when a requirement of at least one virtual network function and endpoint nodes involved in the requirement are input through an input means (401, 402), wherein the optimum path is obtained based on network resource information of the network and computing resource information of servers on which at least one virtual network function can be deployed.
