To better understand the formation mechanism of oligomeric hydroxyalkyl hydroperoxides HOROO(SCI)nH composed of stabilized Criegee intermediate (SCI) as a chain unit, the reactions of SCI with hydroxyalkyl hydroperoxides (HOROOH) and hydroxyalkylperoxy radical (HORO2) as well as HO2 radical were investigated. For the reactions of HORO2 + SCI, two preferred pathways involving a SCI insertion in HOROOH...
Compared to single classifiers, ensemble learning offers significant and stable performance improvement, while ensemble pruning can improve efficiency and performance of the ensembles further, so both of them are hot topics, not only in traditional machine learning but also in recent data stream mining scopes. Aiming to provide a uniform platform and framework for developing and evaluating ensemble...
Using ensemble of classifiers on sequential chunks of training instances is a popular strategy for data stream mining. Aiming at the limitations of the existing approaches, we introduce recalling and forgetting mechanisms into ensemble based data stream mining, and put forward a new algorithm MAE (Memorizing based Adaptive Ensemble) to mine chunk-based data streams with concept drifts. Ensemble pruning...
