Potential of dissimilatory nitrate reduction pathways in polycyclic aromatic hydrocarbon degradation. Luis Torgo main contributions to the state of the art on data mining and machine learning are related with tree-based regression methods and more recently with utility-based forecasting togo.


Data Mining with R. The results of this study contribute to the understanding of the dissimilatory nitrate-reducing pathways and help uncover their involvement in degradation of PAHs, which will be crucial for directing remediation strategies of PAH-contaminated anoxic sediments. Resampling with neighbourhood bias on imbalanced domains. My profile My library Metrics Alerts. Ibero-American Conference on Artificial Intelligence, Trier 1 Trier 2.

Predicted microbial functional analyses revealed clear shifts and interrelationships between genes involved in anaerobic and aerobic degradation of PAHs and in the dissimilatory nitrate-reducing pathways denitrification and dissimilatory nitrate reduction to ammonium – DNRA. However, we observe ttorgo all cross-validation variants tend to overestimate the performance, while torg sequential methods tend to underestimate it. In that case, your data will be automatically deleted from our information system.

Mariana OliveiraLuis Torgo: Abstract This study investigates the potential of an indigenous estuarine microbial consortium to degrade two polycyclic aromatic hydrocarbons PAHsnaphthalene and fluoranthene, under nitrate-reducing conditions.

Standard cross-validation with random selection of examples is significantly worse than the blocked cross-validation, and should not be used to evaluate classifiers in time-ordered data scenarios.
