Data compression method for a classifier in a telecommunication environment utilizing aggregation of data over time periods of increasing length

摘要

A method of classifying a sample of values related to the use of a server, including: recording, by the server, use events in a log; configuring a classifier tool with a behavioral model formed of a weighted list of parameters, establishing a sample of values from the log, and supplying it to a classifier tool, which calculates a score representative of the adequacy of the sample to a target category, reading recent use events saved in the log and aggregating them over basic time intervals, storing the aggregation result obtained for each basic interval in a distinct record of a first group; aggregating, when the number of records of the first group reaches a threshold, the contents of the records of the first group in a distinct record of a second group, and establishing the sample from the contents of records of the database.
