A method for improving user experience associated with an application supported by a system is provided. The method comprises obtaining input data associated with a group of one or more features and determining a performance score associated with the obtained input data using a performance score generating model. The performance score indicates an estimated quality of user experience (QoE) of the application. The method further comprises determining whether to apply a configuration change based on the determined performance score. The configuration change is associated with the application and/or the system.

Modelling and optimization of quality of experience

Apparatuses and methods for anomaly detection. In one embodiment, a method is implemented in a computing device for building a tree structure to represent a system behavior includes obtaining one or more training log records; and building a tree structure using the one or more training log records. The tree structure includes a plurality of tree nodes. Each successive tree node in a root-to-leaf path of the tree structure representing successive log elements of the one or more training log records. Each of the one or more training log records includes one or more log elements. In one embodiment, a method implemented in a computing device for fault detection includes obtaining a live log record and determining an anomaly in the live log record by comparing corresponding successive elements of the live log record to successive nodes in a root-to-leaf direction of the tree structure.
