Welcome to my personal website! Here I share some of my little projects.

  • LU decomposition from scratch

    Implementation of the LU factorization in Python. Description Linear systems of the form ${\bf Ax}={\bf b}$ are essential in Linear Algebra and they appear in multiple applied contexts. When ${\bf A}$ is an $n \times n$ matrix, we know the $n \times 1$ solution vector ${\bf x}$ is unique, but that doesn’t mean it’s easy to find.

  • Simple convolutional neural network for digit recognition

    Assignment for “Knowledge technology”, course in the Master in Methodology for behavioral sciences. Description The purpose of the the project wasn’t to develop a sophisticated architecture (see the image below to get a sense of what kind of network we built) or to get highest accuracy in a test set.

  • Helping behavior during COVID-19 lockdown

    This brief research project was part of the course “Linear models” in the Master in Methodology for behavioral sciences. Description Why we help other people is a question psychologists have been trying to answer for decades.
