Stream mining considers the online arrival of examples at high speed and the possibility of changes in its descriptive features or class definitions compared with past knowledge (i.e., concept drifts). The fast detection of drifts is essential to kee

Traditional supervised machine learning algorithms conduct data classification in a flat way, i.e., they seek to associate each example with a class belonging to a finite, devoid of structural dependencies and usually small, set of classes. However,

Analysing Spatio-Temporal Voting Patterns in Brazilian Elections Through a Simple Data Science Pipeline

Autor: T. P. da Silva, Antonio Rafael Sabino Parmezan, L. H. M. Jacintho, Gustavo E. A. P. A. Batista

Publikováno v: Journal of Information and Data Management. 12

Since 1989, the first year of the democratic presidential election after a long period of a dictatorship regime, Brazil conducted eight presidential elections. Short and long-term shifts of power and two impeachment processes marked such a period. Th
