About

Heyo! I鈥檓 Matias 馃憢. I鈥檓 interested in a couple of topics, mainly around Computer Vision. Lately, I鈥檝e been broadly interested in diffusion and flow-matching methods, differential equations in machine learning, and generative methods in general. I recently finished my Master鈥檚 in CS at Universidad de Buenos Aires, and I鈥檓 currently looking for PhD opportunities.

This site鈥檚 purpose is to be a polished digital notebook. It somewhat reflects my different thoughts on the various subjects I鈥檓 interested in learning or researching. I sometimes take notes and add them here as blog posts. They take an incredibly long time to produce, and, as I don鈥檛 have much free time, I post much more infrequently than I want to.
