The invention discloses a complex event processing system based on machine learning and a deploying method of the complex event processing system. The complex event processing system comprises an event detection algorithm managing module, a system feature extracting module, a deployment scheme managing module, a system deploying module, a user feedback acquiring module and an environment feature extracting module. The deploying method comprises the following steps: at first, the event detection algorithm managing module and the system feature extracting module are informed of business rules to be customized and system response requirement according to the business rules customized by a user; and then the system deploying module takes the charge of deploying the scheme selected by the deployment managing module, the user feedback acquiring module distributes user identification for captured system response, the environment feature extracting module acquires the features of the current environment, and the deployment scheme managing module optimizes the current deployment scheme. According to the complex event processing system based on machine learning and the deploying method of the complex event processing system, the deploying method can be optimized according to the deployment environment, and the complex event processing system which meets the demands of the deployment environment can be deployed.
