BI Trip 2018: BI students visit Acumen

This blog post is contributed by Elseline Senave, Laura Verboven, and Greg Van Houdt, students of the bachelor and master program Business Informatics

Everyone with a memory to their student-life knows the feeling… You spend your precious time at the University, get heaps of knowledge thrown at you and eventually reach your breaking point when you’re working against the deadline of yet another project. It is at those moments that a student wonders whether all your efforts will actually be worth the investment. “How will any of this do me any good in my daily life?”

It’s all about the process

The world and the industry has changed radically in recent years. Of course, evolutions and revolutions have become commonplace in modern economies. This time, however, is different. It is not the products and services that are changing, it is the way in which they are delivered to the customer that is totally different.

The guest lecture is part of the BPM course in Master of Management and the speaker is Jan Mendling, professor at the Wirtschaftsuniversität Wien and thought leader in the area of Business Process Management.

The future of conformance checking: identifying challenges and opportunities

On the 8 and 9th of February 2018, we gathered with an international group of process mining researchers to discuss the many challenges in the field of conformance checking. The event was organized by the Flemish Scientific Research Community on Process Mining (htpps://www.srcprocessmining.org), a community that is led by our research group, together with KULeuven and UGent. The brainstorm session was attended by researchers from the Polytechnic University of Catalonia, the Pontifical Catholic University of Chile,  RWTH Aachen University, the Technical University of Eindhoven and the Wirtschaftsuniversität Wien.

BI-students think outside the box: “Don’t worry, BI happy”

This blog post is contributed by Elseline Senave, Nick Baeten and Stef Breuls, students of the bachelor program Business Informatics

It goes without saying that it has plenty of perks to be a BI student. You get to explore some of the most compelling subject-matters, to tackle cutting-edge challenges and to forge a connection between what is and what shall be. But wait, it gets even better: on the seventh day, we created something called “BI-day”, which basically means that we get to dive right into the action whilst the other university students get to follow classes from dawn to dusk.

bupaR: Business Process Analysis with R

Organizations are nowadays storing huge amounts of data related to various business processes. Process mining provides different methods and techniques to analyze and improve these processes. This allows companies to gain a competitive advantage. Process mining initiated with the discovery of work-flow models from event data. However, over the past 20 years, the process mining field has evolved  into a broad and diverse research discipline.

Why should we trust your algorithm?

There is no doubt about the current role of Machine Learning in the fascinating world of Business Intelligence. Predicting whether a customer will be loyal to the company or not, understanding customers’ behavior or anticipating market fluctuations are typical examples on which Machine Learning may be pivotal. Unfortunately, most successful Machine Learning algorithms like Random Forests, Neural Networks or Support Vector Machines do not provide any mechanism to explain how they arrived at a particular conclusion and behave like a “black box”. This means that they are neither transparent  nor interpretable. We could understand transparency as the algorithm’s ability to explain its reasoning mechanism, while interpretability refers to the algorithm’s ability to explain the semantics behind the problem domain.

useR!2017: Analysing Learning Patterns with R

Teaching R to students with little to no experience in programming or data analysis is a challenging task. Our talk at useR!2017 showed how different ingredients of our course Exploratory and Descriptive Data Analysis at UHasselt are used to facilitate the learning of R.

Firstly, the educational environment at UHasselt, based on guided self-study and the use of small group working sessions, allows each student to have an individual pace of learning and gives them frequent feedback.

A not so gentle introduction to text and opinion mining

Currently, Professor Leticia Arco García of the Central University of Las Villas (Cuba) is visiting our research group. As a member of the Computer Science Department of the Artificial Intelligence Lab, she is an expert within the domain of text mining. Given her expertise and our curiosity, we asked her if she could give an introduction seminar. And so she did, by organizing not one but two seminars, one on text mining and one on opinion mining.

Students visit the Intel facilities in Ireland

Traditionally, the students business informatics of UHasselt organise a biennial trip to visit leading-edge technology companies around the world. This year, our group had the pleasure to visit the Intel facilities in Dublin. For sure, Intel did a wonderful job in having us. The staff showed real commitment and organised a very interesting day filled with talks, demonstrations and tours.

What steps to take when using machine learning for text classification: a case study at a transportation company

The problem

The problem we are addressing originates at a transportation company. When analyzing the results of their shipments, they would like to break this down into categories. For example, how many packages contain clothing and how many contain laptops, and does different content lead to different results during shipment. Instead of having to manually label all these packages, we look for a more efficient solution. The goal of this blog post is to show you the steps we took to solve this problem using machine learning. Steps that can be followed when you undertake your own machine learning projects.
