Greetings

I am Kokos [he/him]. I enjoy (occasionally) thinking, reading, and talking about stuff at the intersection of formal logic, linguistics, and machine learning. This website tracks and presents (some of) my work.

Whereabouts / Short CV

On my day to day, I am a post-doctoral researcher at Aalto University, where I do neurosymbolic machine learning. Twice a week, I exceptionally do climate stuff with neural networks for Skyfora. Beginning in September 2024, I will be visiting the University of Bologna for a few months.

Before moving to Helsinki, I was located in Utrecht. I received my PhD (CompLing) and my master's degree (AI) from Utrecht University. While in Utrecht, I was also working as a machine learning engineer for geekbot. Before all that, I received my diploma in Electrical & Computer Engineering from the Aristotle University of Thessaloniki.

A longer version of the above can be found at my CV.

Research

My published research revolves around structured machine learning, neurosymbolic reasoning, and type-driven approaches to syntactic parsing and semantic compositionality, among other things. I am especially interested in the interface between formal and data-driven methods; if that floats your boat rubber duck, you can have a look at my publications page.

My latest output is "Nominal Class Assignment in Swahili: A Computational Account" (Preprint, October 2024).

Thesis

My dissertation is titled Dependency as Modality, Parsing as Permutation: A Neurosymbolic Perspective on Categorial Grammars. It advocates for the use of modalities as dependency annotations in type-logical grammars, and explores the parsing-as-deduction paradigm from a contemporary neurosymbolic perspective.

People thought it was good: it is one of the two recipients of the 2024 E. W. Beth Dissertation Prize. You can find a faithful copy of the physical print here. If (for whatever reason) you're interested in an actual physical copy, feel free to send me a message.
