Dahlquist Barrier and Symplectic Integrator For Time-Stepping The Wave Equation

So it’s holiday time and I find some times to write, my objective today would be to present and idea regarding how to use the first and the second Dahlquist barrier theorem to prove some theoretical limit of symplectic integrator. Introduction In this first section we will focus our attention to the numerical method to …

Arnoldi Iterations

During my first year of undergraduate Maths degree at University of Pavia I was seriously evaluating the possibility to change degree course to something more related to Software Engineering. Thankfully I came across the course of Numerical Linear Algebra, I remember that during that course ideas that I hadn’t fully understood until that moment become …

Digit Recognition

Recently our student association has organised a Machine Learning Course at Collegio Ghislieri, more  detail can be found here, during this course a variety of  topics were touched. At the end of this course we have organised a competition, which consisted into writing the most accurate Neural Network  (NN) for digit recognition. One of the …
