Biography

I am a post-doctoral fellow at the Faculty of Computer Science at Dalhousie University. My research focuses on predictive analytics for dependent data, and I am developing an interest in explainable AI.

I have a PhD from the MAPi Doctoral Programme in Computer Science, hosted at Faculty of Sciences, University of Porto (FCUP) and the Laboratory of Artificial Intelligence and Decision Support (LIAAD – INESC TEC). My work was fully funded by a FCT-MAPi scholarship, under the supervision of Prof. Luís Torgo and Prof. Vítor Santos Costa.

Biased resampling strategies for imbalanced spatio-temporal forecasting

In this extension paper, we expand on our proposals for a new set of resampling strategies for imbalanced spatio-temporal numeric forecasting tasks, by introducing bias into formerly random processes.

Evaluation Procedures for Forecasting with Spatiotemporal Data

In this paper, we empirically compare several variants of cross-validation (CV) and out-of-sample (OOS) performance estimation procedures, using both artificially generated and real-world spatiotemporal data sets.
