In recent years, several screening methods have been published for ultrahigh-dimensional data that contain hundreds of thousands of features, many of which are irrelevant or redundant. However, most of these methods cannot handle data with thousands of classes. Prediction models built to...

One of the primary objectives underlying the extensive 20-year development of the TS Fuzzy model transformation (originally known as TP model transformation) is to establish a framework capable of generating alternative Fuzzy rules for a given TS Fuzzy model, thereby manipulating the associated...

The age of big data and machine learning technologies brought the new flourishing of artificial intelligence research along with profound innovation in digital services A global AI race is underway, and the EU seeks to play a determining role in it, by exploiting its scientific abilities and...

Data integration plays a crucial role in crisis management and city resilience use cases by enabling the consolidation of information from scattered sources into a unified view, thereby allowing decisionmakers to gain a more complete and accurate understanding of the situation at hand. In this...

The lack of freely available (real-life or synthetic) high or ultra-high dimensional, multi-class datasets may hamper the rapidly growing research on feature screening, especially in the field of biometrics, where the usage of such datasets is common. This paper reports a Python package called...

The article describes the stepwise process of the introduction of digitization and its multi-field impacts through diverse subjects taught in the Budapest Corvinus University. The various aspects of digitalization play ever growing role in most, increasingly in every fields of economy -...

The recent emergence of mercenary spyware like Pegasus or Russia’s ongoing conventional warfare in Ukraine, supplemented by a cyber offensive we never experienced before, made cybersecurity even more critical. Despite the considerable research in the field, it seems that academia and the...

This study aims to investigate the phenomena of how artificial intelligence (AI) as one of the cutting-edge technologies benefits restaurant services and what the obstacles to implementing AI in a restaurant are. Due to the rapid pace of life, people tend to have less and less eating time,...

As part of the most recent developments in human co-evolution with information and communication technologies, the increasing complexity of our digital realities, as well as the expanding capabilities of omni-present artificial intelligence, are having profound implications. This transformative...
