    • From one-class to two-class classification by incorporating expert knowledge

      Oosterlinck, Dieter; Benoit, Dries F.; Baecke, Philippe (2018)
      In certain business cases the aim is to identify observations that deviate from an identified normal behaviour. It is often the case that only instances of the normal class are known, whereas so called novelties are undiscovered. Novelty detection or anomaly detection approaches usually apply methods from the field of outlier detection. However, anomalies are not always outliers and outliers are not always anomalies. The standard one-class classification approaches therefore underperform in many real business cases. Drawing upon literature about incorporating expert knowledge,we come up with a new method that significantly improves the predictive performance of a one-class model. Combining the available data and expert knowledge about potential anomalies enables us to create synthetic novelties. The latter are incorporated into a standard two-class predictive model. Based on a telco dataset, we prove that our synthetic two-class model clearly outperforms a standard one-class model on the synthetic dataset. In a next step the model was applied to real data. Top identified novelties were manually checked by experts. The results indicate that incorporating expert knowledge to transform a one-class problem into a two-class problem is a valuable method.
    • From phonebloks to google project ara. A case study of the application of sustainable mass customization

      Hankammer, Stephan; Jiang, Ruth; Kleer, Robin (2016)
      Mass Customization (MC) has become a major trend in the consumer goods market in recent years. However, it is still unclear if MC goods have a positive impact on the environment due to the many influencing factors in comparison to mass produced goods. With Google’s “Project Ara”, a modular and customizable smartphone approach is very likely to reach market maturity and its economic, social and ecologic impacts are still unclear. Using a qualitative case study approach, we shed light on its potential economic success. Furthermore, we use the two theoretical concepts of Eco Innovation (EI) and Systemic Innovation (SI) to assess Google Ara’s potential to lead to changes in terms of ecologic and social concerns. In our analysis, we show that Project Ara has the potential to outperform its competitors of modular smartphones. We work out that Google’s modular approach could lead to a longer useful life of smartphones – or at least for some components. Finally, we affirm Project Ara’s general potential for being an SI. Even though Project Ara will very likely not change the complete smartphone market and the behavior of the involved actors, there is a potential for influencing sociocultural behavior in the long tail of the smartphone market.
    • From pitch to Q&A: Why do angel investors change their minds?

      Imhof, Zoë; Collewaert, Veroniek (2018)
      Drawing on the elaboration likelihood model, this paper develops and tests a set of hypotheses concerning why business angels change their intentions to invest moving from pitch to Q&A. We test our hypotheses using a sample of 654 real-life angel evaluations of entrepreneurs pitching for money. Our results suggest a change in intentions to invest is less likely to occur when the entrepreneur has a more attractive voice, higher levels of displayed passion and higher levels of perceived coachability. Angels are more likely to change their minds though when they perceive the entrepreneur to be more trustworthy.

    • Further validation of the Cognitive Style Indicator (CoSI)

      Cools, Eva; Vanderheyden, Karlien (2013)
      In this paper we compare the usability of ESOM and MDS as text exploration instruments in police investigations. We combine them with traditional classification instruments such as the SVM and Naïve Bayes. We perform a case of real-life data mining using a dataset consisting of police reports describing a wide range of violent incidents that occurred during the year 2007 in the Amsterdam-Amstelland police region (The Netherlands). We compare the possibilities offered by the ESOM and MDS for iteratively enriching our feature set, discovering confusing situations, faulty case labelings and significantly improving the classification accuracy. The results of our research are currently operational in the Amsterdam-Amstelland police region for upgrading the employed domestic violence definition, for improving the training of police officers and for developing a highly accurate and comprehensible case triage model.
    • The future of internal staffing: A vision for transformational e-HRM

      Rogiers, Philip; Viaene, Stijn; Leysen, Jan (2020)
      Through an international Delphi study, this article explores the new dynamics that are starting to characterize internal staffing, by means of transformational electronic human resource management. Our focus is on three types of information systems that are expected to evolve and be used in function of transformative change in internal staffing systems: human resource management systems, job portals, and talent marketplaces. Together, these systems challenge current knowledge on internal labor market organization, by affording market-like staffing systems that enable employees to construct personalized and self-directed pathways for growth. Further, this article identifies the key challenges for realizing this vision in governments, such as inadequate regulations and funding priorities, a lack of leadership and strategic vision, together with rigid work policies and practices and a change-resistant culture. Tied to the vision in this article, we identify several areas of future inquiry that bridge the divide between theory and practice."
