A study on combining dynamic selection and data preprocessing for imbalance learning
TL;DR: This paper experimentally evaluates the argument that dynamic selection combined with a preprocessing technique can achieve higher performance than static ensemble for imbalanced classification problems and designs a useful experimental framework to integrate preprocessing and dynamic selection.

SWGMM: a semi-wrapped Gaussian mixture model for clustering of circular---linear data
TL;DR: This study proposes a mixture model capable of approximating the distribution of multi-modal circular–linear data and reveals that the proposed mixture model outperforms the other methods in most cases.

An HMM framework based on spherical-linear features for online cursive handwriting recognition
TL;DR: A novel but simple strategy based on the well-known discrete curve evolution for the segmentation task, certain angular and linear features are extracted from the sub-strokes of word samples and are modelled as feature vectors generated from a mixture distribution.
