Hi! My name is Saulo Martiello Mastelini, a Brazilian π§π· who has lived for 18 years in the countryside region of a small city called CΓ’ndido de Abreu in the state of ParanΓ‘, Brazil. Even though I only had daily internet access when I was 19, I fell in love with computer science π» and decided to pursue a career in this field. I moved to Londrina in 2012, and I got my bachelor’s in Computer Science with honors in 2016 at the State University of Londrina (UEL). My final project concerned a computer vision application for grading poultry meat π. By that time, the researchers involved in the project and I wrote a paper π which is, to this date, one of my most cited works.
I started my Master’s in 2016 at the same university. In the beginning, I intended to research computer vision π, in a time when deep learning had not still got the spotlight π¦. My plans to automatically tune a local contrasting enhancing algorithm using particle swarm π¦ optimization didn’t work out as I expected. So, I had to come up with an alternative action plan. My advisor at that time, Sylvio Barbon Jr., introduced me to multi-target regression (MTR) problems and I’m so grateful that he did this π. I had a passing knowledge of machine learning, and it suddenly became my main research interest! Good times π₯³! I will never forget the friendship I made and the plethora of things I learned at UEL. After a lot of study and research, Sylvio and I published a good number of papers about MTR. I also created a simple toolkit in R to benchmark MTR problems. At the end of my Master’s, I learned about data streams πββοΈ and online machine learning, and it felt like a natural path π£οΈ to pursue from where I was research-wise.
In 2018, I moved to SΓ£o Carlos to start my Ph.D. under the supervision of professor AndrΓ© Carlos Ponce de Leon Ferreira de Carvalho in the Institute of Mathematics and Computer Science (ICMC) from the University of SΓ£o Paulo (USP). My research is supported π΅ by FAPESP. At ICMC, I once again found a wonderful and chaotic (in a good sense) workplace! I made a lot of new friends that I keep, in the same way as the ones from UEL, to this day.
My central research theme is online machine learning regression, primarily using decision trees π± and rules π. Specifically, my thesis goal π‘ is to make existing online regressors more efficient regarding memory and running time while keeping their predictive performance! During my Ph.D., I started collaborating with the scikit-multiflow
project and ended up becoming one of its maintainers. In 2020, the core developers from scikit-multiflow
and creme
joined forces to create River π! So, I am a proud founding member and maintainer of the to-go library on online machine learning in Python!
From February 2022 to September 2022, I am living in Europe πͺπΊ as a visiting researcher at INESC-TEC/University of Porto! My current research goal is to build π§ more efficient online k-Nearest Neighbor algorithms under a sliding-window regimen. Let’s see how that goes!
I love dogs πΆ, reading π, playing guitar πΈ and singing π΅, doing some trekking β°οΈ and spending time with people I love β€οΈ! I formulated some of my best ideas and proposals in a mountain or amidst trees π².

This is me at the Louvre museum! Despite this picture, taking selfies is not among my hobbies π
