I am Dennis Ulmer, PhD student for NLP at ITU.
My current research interests include uncertainty estimation methods with application to Natural Language Processing, learning for low-resource languages, compositionality, inductive biases and much more!
My background includes an undergraduate degree in Computational Linguistics from the University of Heidelberg and a master's degree in Artificial Intelligence from the University of Amsterdam, where I wrote
my thesis under Dieuwke Hupkes and Elia Bruni. I am currently a student under Natalie Schluter at the NLPnorth group @ IT University Copenhagen.
