Talk Science to Me - Robert Legenstein

Four years ago, Robert Legenstein last spoke on the podcast about his research into artificial intelligence. Shortly afterwards, ChatGPT was launched. In this interview, he explains what has happened since then.

Talk Science to Me - Roman Kern

Roman Kern investigates how insights about the real world can be gleaned from large datasets. We spoke about the state of research back in 2023 – but what has changed since then?

Talk Science to Me - Elisabeth Lex

Elisabeth Lex wants to make artificial intelligence and algorithms fairer and more accessible. She explains how this can be achieved and how her research has evolved since 2023.

Talk Science to Me - Alexander Felfernig

Can recommender systems help tackle climate change whilst finding us tailor-made holidays? Alexander Felfernig is exploring this and many other questions relating to artificial intelligence at the Institute of Software Engineering and Artificial Intelligence at TU Graz.

Talk Science to Me - Bettina Könighofer

Do you know how artificial intelligence makes decisions? Why an autonomous vehicle brakes at that precise moment? Why a large language model gives exactly that answer? No? Then you’re in the same boat as pretty much everyone else. Because artificial intelligence is not very transparent. Bettina Könighofer works in this field and wants to make artificial intelligence fast, yet at the same time safe and explainable.
