Improving Maritime Traffic Emission Estimations on Missing Data with CRBMs

1 code implementation7 Sep 2020 Alberto Gutierrez-Torre, Josep Ll. Berral, David Buchaca, Marc Guevara, Albert Soret, David Carrera

Unfortunately, these models are sensitive to missing or corrupted data, and therefore they need data curation techniques to significantly improve the estimation accuracy.

Sequence-to-sequence models for workload interference

no code implementations25 Jun 2020 David Buchaca Prats, Joan Marcual, Josep Lluís Berral, David Carrera

In this work we propose a methodology for modeling co-scheduling of jobs on data-centers, based on their behavior towards resources and execution time, using sequence-to-sequence models based on recurrent neural networks.
