Title:
COMMUNICATION ANALYSIS DEVICE, COMMUNICATION ANALYSIS METHOD, COMMUNICATION ANALYSIS SYSTEM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/281684
Kind Code:
A1
Abstract:
According to the present invention, to make it possible to improve the accuracy of a learning model for the analysis of a communication packet, extraction data used for the analysis of the communication packet is extracted from the communication packet; noise data, which causes a reduction in learning accuracy, is removed from the extracted extraction data; a learning model, which receives the extraction data as input data and outputs a result of analyzing the extraction data as output data, is generated by unsupervised learning by using post-removal data, which is obtained by removing the noise data from the extraction data, as training data; the extraction data is analyzed by using the learning model; and a result of analyzing the extraction data is output as an analysis result of the communication packet.
