An online conformance checking technique based on Hidden Markov Models (HMM).

About

This was a work that I did during my research visit at DTU in Denmark. The technique tackles the online conformance checking problem where one would like to continuously evaluate the conformance of events coming in at an event stream. It focuses on the challenge of having to balance between making sense at the process level as the case reaches completion and putting emphasis on the current information at the same time.

For more detail, please checkout the Github repo, where the related code and paper (under review) can be found.

A web demo on a real-life dataset can also be found here. The real-life dataset is on a hospital billing process which can be found here.
