About me

My name is Szymon Chojnacki. I am an assistant professor at the Insitute of Computer Science of the Polish Academy of Sciences. I work with the Foundations of Artificial Intelligence Group under the supervision of Mieczyslaw Klopotek. My research is focused on an application of machine learning algorithms to unstructured data modeling. I am interested in techniques with sound mathematical foundations. My most recent activity comprises three topics:

  • social networks
  • text stream clustering
  • recommender systems
I develop the concept of recommending newly created objects. Read more about recommeding newly created objects.
