The 2011 International Joint Conference on Neural…
The aim is to investigate the relevance of using weights to improve supervised link prediction, and the preliminary results on supervised prediction on a co-authorship network revealed satisfactory results when weights were considered.
Ranking and selecting clustering algorithms using a meta-learning approach
- M. D. SoutoR. Prudêncio Alexander Schliep

Computer Science
A novel framework that applies a meta-learning approach to clustering algorithms that provides a ranking for the candidate algorithms that could be used with that dataset in the context of cancer gene expression micro-array datasets is presented.
Time Series Based Link Prediction
- Paulo Ricardo da Silva SoaresR. Prudêncio
- 10 June 2012
Computer Science
The preliminary results using two link prediction methods (unsupervised and supervised) on co-authorship networks revealed satisfactory results when temporal information was considered, and a forecasting model was deployed on these time series and used as the final scores of the pairs.

Experiments on synthetic and benchmark datasets demonstrate the proposed measures can provide a complementary instance hardness perspective when compared to those from related literature.
A Multi-objective Particle Swarm Optimization for Test Case Selection Based on Functional Requirements Coverage and Execution Effort
- Luciano S. de SouzaP. MirandaR. PrudêncioF. Barros
- 7 November 2011
Computer Science
A mechanism for functional TC selection which considers two objectives simultaneously: maximize requirements' coverage while minimizing cost in terms of TC execution effort and two multi-objective versions of PSO are implemented.
Predicting the Performance of Learning Algorithms Using Support Vector Machines as Meta-regressors
- Silvio B. GuerraR. PrudêncioTeresa B Ludermir
- 3 September 2008
Computer Science
In this work, we proposed the use of Support Vector Machines (SVM) to predict the performance of machine learning algorithms based on features of the learning problems. This work is related to the…
