Data Science and Artificial Intelligence
As the field of Data Science matures, we need to define a standard approach how to implement Data Science and AI projects in practice.
The DASC-PM model defines a standard approach for data science projects, read the full paper here DASC-PM v.1.0 - Ein Vorgehensmodell für Data-Science-Projekte (in German)
Companies in particular face many challenges implementing AI in their organization. In many cases, technical infrastructure and talent are major hurdles but even if these are available, organizational and business aspects are even more challening in practical applications. Identifying suitable use-cases is of critical importance for companies to derive value from AI. The “Enterprise AI Canvas” Journal Preprint offers a structured approach and guidance how to start an AI project in a company.

Algorithms
Data Science and AI are driven by the underlying algorithms that are used to transform data into predictions.
The NeuroBayes neural network package (developed with Prof. Dr. M. Feindt) is a sophisticated 3-layer feed-forward network that can be used either for classification or for regression. It’s main advantages are that it does not overtrain and, in case of regression, can predict entire probability density distributions. These distributions include all information about the predicted event, including the uncertainty.
Most machine learning algorithms are “black boxes” in the sense that individual predictions cannot be understood in detail. The novel algorithm Cyclic Boosting Journal Preprint (with Dr. F. Wick and Prof. Dr. M. Feindt) allows to calculate accurate precisions where the underlying “factors” for each prediction can fully explain how individual predictions were made.
AI in Education
I’m part of the AI in Education initiative at IUBH where we focus on finding novel ways how AI technologies can aid the learning experience. Recently, the contribution “On Demand Tutoring in Distance Learning” by two of my Master’s students was accepted at the conference “Educational Research (Re)connecting Communities” (ECER2020) - though unfortunately, the conference itself was cancelled due to Covid-19.

Together with Prof. A. Hollstein, we also start a survey about the digitalization in German schools EduC
