Title:
SYSTEM, METHOD, INFORMATION PROCESSING DEVICE AND PROGRAM
Document Type and Number:
Japanese Patent JP2021064242
Kind Code:
A
Abstract:
To provide a system, a method, an information processing device and a program, which detect an abnormal gradient in machine learning.SOLUTION: A system includes: a gradient calculation unit 313 that calculates a gradient on the basis of parameters of a machine learning model recorded in acquired learning target data and block chain (BC); an abnormality detection unit 322 that detects an abnormality of the gradient by using a GAN of a teacher absence learning model; an abnormality detection unit 332 that detects an abnormality of the gradient by using a GAN of a semi-teacher presence learning model; a detection result comparison unit 333 that compares the abnormality detection result detected by each abnormality detection unit to extract a common detection result; a parameter calculation unit 324 that calculates parameters updating the machine learning model on the basis of the common abnormality detection result; a block generation unit 325 that generates a new block including the updated parameters; and BC management units 311, 321 and 331 that add the generated block to the BC.SELECTED DRAWING: Figure 3
