I am a PhD student at ÚFAL, writing my thesis under RNDr. Pavel Pecina on the topic of Neural Network Models for Intepretation of Multimodal Data. This work is done for the CEMI project. In 2016, I started focusing on Optical Music Recognition (with the eventual goal of applying these multimodal models).

My Mgr. thesis, also under RNDr. Pecina, was on the topic of automatically selecting images for news articles. This work was also done for the CEMI project. My thesis is available here: Matching Images to Texts

I have previously worked on the SEANCE project on Sentiment Analysis, with my Bc. thesis and in the following years.
