28th September 2018, scientists from our department: Dr. Bartosz Perkowski and Piotr Kałużny, MSc., as an every year tradition, have organized classes during the “Researchers’ Night”. This time the topic of their lectures however was different, because it was oriented on a very serious topic “How Artificial Intelligence works” and was very popular among the participants. There was a multitude of questions to our scientists about the prepared topic, which presented the practical elements of building and using neural networks, which only confirms that this seemingly complicated topic can be extremally interesting for the younger participants.
