preprint

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

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.
