I got a BSc in Physics before I went on to get a MSc in Computer Science at the Faculty of Sciences, University of Porto. I am now working towards a PhD in Informatics through the MAP-I program. My research interests are mostly in Data Mining / Machine Learning, focusing on predictive analytics for dependent data.

Abstract
We present and evaluate two different methods for building spatio-temporal features: a propositional method and a method based on propositionalisation of relational clauses. Our motivating application, a regression problem, requires the prediction of the fraction of each Portuguese parish burnt yearly by wildfires - a problem with a strong socio-economic and environmental impact in the country. We evaluate and compare how these methods perform individually and combined together. We successfully use under-sampling to deal with the high skew in the data set. We find that combining the approaches significantly improves the similar results obtained by each method individually.
