Final oral examination is set as personal appointment. The oral examination should be taken before Friday 01 February 2019.
Process Mining is a growing branch of Data Science that analyses event data recorded in Information Systems and focuses on the process perspective. Investments in Process Mining from public and private companies are steadily increasing, and expected to more than double in the next five years. Hence a good knowledge of Process Mining is an important skill for Data Scientists.
Conformance Checking is a part of Process Mining discipline and consists in techniques to compare the process model and the real behavior recorded in an Information Systems to find commonalities and discrepancies. These may signal the need of better control of the process, or that the model needs to be improved to capture reality better.
Common implementations of Conformance Checking on Information Systems are event listeners that trigger some kind of alert when deviations occur, or post-mortem analysis to detect fraudulent behavior, for example violations of the Four Eyes Principle.
This Software Lab course includes tutorials, guest lectures and hands-on for the existing Conformance Checking algorithms using ProM Framework. The course includes implementation of Conformance Checking using Python and following the software engineering principles.
All the above topics will be introduced briefly. Participation is mandatory throughout the course. In the introductory sessions, topics will be assigned to the students and deadlines for submitting the report and implementation will be discussed.
The first part of this course wants to provide students an overview of current implementations of Conformance Checking approaches in the ProM framework:
- Token-based replay
- Alignment based replay
In addition other approaches and variants of the algorithms will be discussed. Students at the end of first part should know how to use these approaches, understand the current implementations and their limitations.
In the second part of the course, students will be required (in groups of at most 4 people) to implement a new Conformance Checking plug-in in a new framework (based on the Python language). The plug-in will implement one of the available approaches (token, alignment), and will have to display problems directly on the process model (using for example colors or interactions).
A written report on the implementation, its advantages and issues should be produced individually by the students. A proper SDLC lifecycle will be followed during this phase to track the development. The details of the methodology will be communicated in the introductory session. At the end of the course, the students should have gained a valuable know-how of Process Mining applications, with a focus on Conformance Checking, and be able to implement the techniques on top of existing Information Systems.
The grading will consist in some individual oral questions on the written report and on the Python plug-in implemented (around 15-30 minutes per student).
- Software Engineering knowledge (Design, development and testing)
- Prior programming experience. Not necessarily Java or Python.
- Interest to learn and code in Python
- Coursera "Process Mining: Data Science in Action" course
- BPI Course
The registration is carried out by the central registration process in July 2018.
