I got a PhD in applied math not so long ago. I like inverse problems and optimization. I also drink a lot of coffe ☕
New paper out! Together with my postdoc advisors @esoubies.bsky.social and Cédric Févotte :)

We study the optimization landscape of L0-Bregman relaxations, which naturally arise when one optimizes non-quadratic fidelity terms coupled with the L0-norm.

My first tweet is going to be rather philosophical: the amount of cultural inputs we receive just because of being in an academic environment is huge. And we should be thankful for that.

Se acabó. Fue un placer, un dolor, un orgullo. Y "La última" casi una catarsis, porque el odio y la mentira intoxican si pasas mucho tiempo cerca. Sirvió, claro que sirvió. No hay más que ver las reacciones histéricas que generaba. Gracias!
