Hierarchical Time-Series Clustering for Data Streams (2008)

Pedro Rodrigues, Joao Gama, Joao Pedro Pedroso

This paper presents a time-series whole clustering system that incrementally constructs a hierarchy of clusters. The Online DivisiveAgglomerative Clustering (ODAC) system is an incremental...

Verifying Properties of Neural Networks (2007)

Pedro Rodrigues, J. Félix Costa, Hava T. Siegelmann

Abstract. In the beginning of nineties, Hava Siegelmann proposed a new computational model, the Artificial Recurrent Neural Network (ARNN), and proved that it could perform hypercomputation. She also...

Physiological Data Modeling Contest (2007)

João Gama, Pedro Rodrigues

The physiological data is characterized by large amounts of data, sequential data, issues of sensor fusion, and a rich domain complete with noise, hidden variables, and significant effects of...
