Understanding covariate shift in model performance
Three (3) different methods (logistic regression, covariate shift and k-NN) were applied to five (5) internal datasets and one (1) external, publically available dataset where covariate shift existed. In all cases, k-NN's performance was inferior to either logistic regression or covariate shift. Surprisingly, there was no obvious advantage for using covariate shift to reweight the training data...

متن کاملUnderstanding the Growth by KILT Model and TYPUS Metrics
The goal of the study is investigating the odd claim of the human civilisation, which modifies the wild natural surrounds by synthetic alterations, defined improvements, bestowing ‹value added›. Indeed, the history seems sanctioning that the ‹life-quality› on the earth has been expanding, with enhanced chances and increased resources, compared to the native prospects of the wilderness. Only at ...
متن کاملPerformance Metrics for Model Fusion in Twitter Data Drifts
Ensemble approaches have revealed remarkable abilities to tackle different learning challenges, namely in dynamic scenarios with concept drift, e.g. in social networks, as Twitter. Several efforts have been engaged in defining strategies to combine the models that constitute an ensemble. In this work, we investigate the effect of using different metrics for combining ensembles’ models, specific...
