Regensburg Colloquium of Information Systems, Computer Science & Mathematics (ReCICM)

The Regensburg Colloquium of Information Systems, Computer Science & Mathematics (ReCICM) is a series of talks and lectures by OTH Regensburg faculty and selected invited speakers from Germany and abroad. ReCICM's objective is to provide a fresh perspective on contemporary issues in the field of Information Systems, Computer Science, and Mathematics from a practitioner as well as from a scholarly perspective.

Coordinating contact is Prof. Dr. Markus Westner.

Summer term 2021

Abstract

As an alternative to PowerPoint, Keynote, and LaTeX Beamer, the HTML-based presentation framework reveal.js can be used to create slides. The benefit of "developing" slides in HTML is flexibility and extendability. reveal.js supports interactive and multimedia elements, animations, syntax highlighting for code, and much more.

Abstract

The Azure cloud platform is not just someone else’s Computer, it’s a set of over 200 different products and services that are designed to help you bring new solutions to life. This lecture will give you an overview of how the Azure Cloud works, the differences of the services and how to use them. Beside the theoretical approach on the Azure Cloud you will also see some Life-Demo.

Abstract

Between 1970 and before the SQL:1999 standard, every data value within a table cell had to be atomic (a scalar value). Since then, new features were introduced to support user-defined structured data types, compound types (like arrays or multisets), and native data types for storing and querying XML and JSON. This talk gives a brief overview of these SQL features which allow storing complex and schemaless data within a relational database.

Abstract

The SQL:2016 standard introduced a native JSON datatype and functions to build and query JSON data. In this talk, we take a look at different implementations of SQL/JSON in PostgreSQL, Oracle, and MariaDB. Some store JSON data as strings, some use a binary representation. PostgreSQL supports generalized inverted indexes (GIN) on JSON data, for the other DBMSs, we will learn some workarounds using expression indexes or virtual columns.

Abstract

Many problems of industrial interest are NP-complete, and quickly exhaust resources of computational devices with increasing input sizes. Quantum annealers (QA) are physical devices that aim at this class of problems by exploiting quantum mechanical properties of nature. However, they compete with efficient heuristics and probabilistic or randomised algorithms on classical machines that allow for finding approximate solutions to large NP-complete problems. While first implementations of QA have become commercially available, their practical benefits are far from fully explored. To the best of our knowledge, approximation techniques have not yet received substantial attention.

In this talk, we explore how problems’ approximate versions of varying degree can be systematically constructed for quantum annealer programs, and how this influences result quality or the handling of larger problem instances on a given set of qubits. We illustrate various approximation techniques on both, simulations and real QA hardware, on different seminal problems, and interpret the results to contribute towards a better understanding of the real-world power and limitations of current-state and future quantum computing.

Interpretable Semantic Similarity Measurement

Abstract

Currently, there is a wide range of solutions to determine the semantic similarity between pieces of textual information. In this sense, solutions such as BERT or ELMo have been able to obtain the best results. However, their neural nature makes them difficult to be interpreted by a human operator. For example, BERT requires 12 layers of neurons plus 12 attention windows, which makes it a black box model. In this talk, we will address the design of solutions that, without renouncing the accuracy of the results, pay special attention to the interpretability of the resulting model. For this, we look at penalized regression, fuzzy logics, and genetic programming schemes. As a result, we have been able to obtain models that obtain quite good results and that can be understood by people from the beginning to the end.
