About

Myself

Kaixo! I'm Aritz, a data scientist and middle distance runner.

My background is in physics and statistics, and I enjoy exploring state-of-the-art statistical- & data science methods. My favorite programming languages are R and Python.

If you keep scrolling down, you will discover some of my projects and get to know more about me.

R

Race visualizer

A visualization tool designed to enhance the broadcast experience of middle and long-distance races, inspired by the dynamic visualizations showcased by World Athletics in recent championships, particularly for the jump and throw events. The tool provides real-time insights into athletes' pace, split times, and estimated finishing times, offering a more engaging and informative viewing experience. Ideal for broadcasters, this tool aims to bring the excitement of real-time data analysis to viewers, particularly during record attempts. This demo showcases the visualization of a world record-breaking 1500m run.

How fast can humans run?

An implementation of "A Simple Random Walk Model for Predicting Track and Field World Records"

A prediction model is built for the men's 100m world record, and human performance limits are estimated using Monte Carlo simulations.

CNN Image Segmentation (bachelor thesis)

The Standard Model of particle physics, while being able to make accurate predictions, has been proved to fail to explain various phenomena, such as astronomical dark matter observations. In this project, a machine learning application is implemented with the goal of studying dark matter candidates. Images from Charge Coupled Devices (CCDs) in different experiments located underground are used to test different deep learning algorithms. A U-Net model is trained with Python's open-source library Keras. The model performs multi-class image segmentation in order to detect dark matter particle signals among background noise.

Image Classification

Image recognition implementation with Keras. A CNN is built and trained with the CIFAR-10 dataset. Two models are trained: one without data-augmentation (77.25% accuracy) and the other with data-augmentation (78.04% accuracy).

EUR/CHF forecast

The goal of this study is to fit an ARIMA model to forecast the EUR/CHF currency exchange rate. Different models are obtained through two trend removal methods: a linear model, and differencing.

Analyzing schizophrenia

A Generalized Linear Mixed Model (GLMM) is fitted in order to study the correlated observations in longitudinal data of patients suffering from schizophrenia. The model parameter estimates reveal that ’male’ patients evolve less favorably than ’female’ patients, while age does not have a significant effect on the evolution of prevalence of thought disorders.
