I had a great time diving into my fork of nanoGPT, the well-known repository by Andrej Karpathy. I spent some time refactoring, adding new features, and running a few experiments regarding training / inference speed.

As part of a university project, I worked on exact optimization methods for the Selective Assessment Routing Problem, a novel post-disaster optimization problem in the domain of Humanitarian Logistics.

Der, Die, or Das? German learners often complain about the nouns having unintuitive and arbitrary genders. How good can a transformer predict the article just by looking at the word? I compare the hardness of this machine learning task against the equivalent for Croatian and Catalan

This is the story of me thinking that building a vocabulary memorization app was the ultimate thing I needed for learning German. And then I just used it for a week.

I’ll tell you about two of my favorite projects during my Master. It’s nice to present them together because they do the same (combinatorial opti) but with different techniques: heuristics vs exact methods.
