Political Media Discourse as an Interactional Space: Presidential TV Addresses to the Nation from a Metadiscourse Perspective [PDF]

open access: yesАктуальные проблемы филологии и педагогической лингвистики, 2023
The study of political media discourse as an interactional space requires an analysis of not only its linguistic characteristics and propositional content but also its metadiscourse component, strategies employed to express speaker’s attitudes and ...

MPSUBoost: A Modified Particle Stacking Undersampling Boosting Method

open access: yesIEEE Access, 2022
Class imbalance problems are prevalent in the real world. In such cases, traditional supervised algorithms tend to have difficulty in recognizing minority data because the models are likely to maximize prediction accuracy by simply ignoring minority data.

Boosting Additive Models using Component-wise P-Splines [PDF]

open access: yes, 2007
We consider an efficient approximation of Bühlmann & Yu’s L2Boosting algorithm with component-wise smoothing splines. Smoothing spline base-learners are replaced by P-spline base-learners which yield similar prediction errors but are more advantageous ...

A Rule Extraction Technique Applied to Ensembles of Neural Networks, Random Forests, and Gradient-Boosted Trees

open access: yesAlgorithms, 2021
In machine learning, ensembles of models based on Multi-Layer Perceptrons (MLPs) or decision trees are considered successful models. However, explaining their responses is a complex problem that requires the creation of new methods of interpretation.
