Abnormal detection system and abnormal detection method of public cloud service

Abstract

An abnormal detection system and an abnormal detection method of public cloud service are provided. The method includes: performing reinforcement learning algorithm on a machine learning model to determine a hyperparameter of the machine learning model, and updating the machine learning model according to the hyperparameter; receiving historical cloud service billing details from a public cloud server, and performing pre-processing to the historical cloud service billing details to obtain historical billing data; inputting the historical billing data to the updated machine learning model to generate estimated cloud service fees; determining whether cloud service fees exceeds the estimated cloud service fees; and outputting an alarm message in response to the cloud service fees exceeding the historical cloud service fees.
