A two-stage model for dealing with temporal degradation of credit scoring
Maria Rocha Sousa, João Gama, Manuel J. Silva Gonçalves
This work is attached to the BRICS 2013 competition. We propose a two-stage model for dealing with the temporal degradation of credit scoring models. This methodology produced moti…
Eigenspace Method for Spatiotemporal Hotspot Detection
Hadi Fanaee-T, João Gama
Hotspot detection aims at identifying subgroups in the observations that are unexpected, with respect to the some baseline information. For instance, in disease surveillance, the p…
EigenEvent: An Algorithm for Event Detection from Complex Data Streams in Syndromic Surveillance
Hadi Fanaee-T, João Gama
Syndromic surveillance systems continuously monitor multiple pre-diagnostic daily streams of indicators from different regions with the aim of early detection of disease outbreaks.…
An eigenvector-based hotspot detection
Hadi Fanaee-T, Joao Gama
Space and time are two critical components of many real world systems. For this reason, analysis of anomalies in spatiotemporal data has been a great of interest. In this work, app…
Event and Anomaly Detection Using Tucker3 Decomposition
Hadi Fanaee-T, Márcia D. B. Oliveira, João Gama +2
Failure detection in telecommunication networks is a vital task. So far, several supervised and unsupervised solutions have been provided for discovering failures in such networks.…
