Giuseppe Carrino website

I am Giuseppe Carrino, but everybody calls me Joseph. In this website you will find different resources about me and my work. I am a first-year PhD student at ENS Lyon since November 2025, supervised by Nicolas Brisebarre, Elisa Riccietti and Theo Mary.

About my research

During my PhD, I focus on second-order optimization methods, especially Newton’s algorithm, and floating-point representation, aiming to reduce computational complexity of high-performing optimizers for Machine Learning tasks. Previously, I worked on a framework for the collection, translation and comparative analysis of online newspaper articles.

About me

Before coming to France, I studied at University of Bologna, completing a Bachelor’s Degree in Computer Science and a Master’s Degree in Artificial Intelligence. I have also been an intern as Software Development Engineer at Amazon Madrid and worked for two months at NTNU in Gjøvik, Norway.

What else?

Nothing much! But I love watching movies - especially if old and italian - and playing the guitar, already setting-up a rock band in Lyon if you want to join :grin:.

Preprint of my first PhD paper!

Published:

The first paper that I worked on during my PhD is now available on HAL and arXiv. It includes an error model for Newton’s methods, when inexactness can arise due to different types of approximations, and the derived convergence theory. What both theory and experiments tell us is that we can use low precision formats to solve Newton’s system almost for free in the majority of cases. If you work on 2nd order optimization, or (wisely) plan to do so, check it out!

Presented my work in a talk at SIAM OP26

Published:

This year I had the great opportunity to attend SIAM OP26 conference at University of Edinburgh. I attended very interesting talks on inexact methods and multi-level optimization, and I presented my work in the mini-symposium on Inexact and accelerated methods for nonlinear problems. My slides are available here.

Poster presented at SIAM Chapters meeting in Milan

Published:

Attending this year “SIAM Chapters meeting for Young Researchers” at PoliMi, I had the opportunity to present a poster on my current work on Mixed-Precision Newton’s method. You can find the poster in PDF here.
