Using dynamical quantization to perform split attempts in online tree regressors

no code implementations30 Nov 2020 Saulo Martiello Mastelini, Andre Carlos Ponce de Leon Ferreira de Carvalho

QO can be easily integrated into incremental decision trees, such as Hoeffding Trees, and it has a monitoring cost of $O(1)$ per instance and sub-linear cost to evaluate split candidates.

Improved prediction of soil properties with Multi-target Stacked Generalisation on EDXRF spectra

no code implementations11 Feb 2020 Everton Jose Santana, Felipe Rodrigues dos Santos, Saulo Martiello Mastelini, Fabio Luiz Melquiades, Sylvio Barbon Jr

In this study, we proposed the Multi-target Stacked Generalisation (MTSG), a novel MTR method relying on learning from different regressors arranged in stacking structure for a boosted outcome.

Online Local Boosting: improving performance in online decision trees

no code implementations16 Jul 2019 Victor G. Turrisi da Costa, Saulo Martiello Mastelini, André C. Ponce de Leon Ferreira de Carvalho, Sylvio Barbon Jr

To increase predictive performance without largely increasing memory and time costs, this paper introduces a novel algorithm, named Online Local Boosting (OLBoost), which can be combined into online decision tree algorithms to improve their predictive performance without modifying the structure of the induced decision trees.
