Background Glenoid version angles are measured to objectively follow changes related to glenohumeral dysplasia in the setting of brachial plexus birth palsy. Measuring glenoid version on cross-sectional imaging was initially described by Friedman et al. in 1992. Recent literature for non-dysplastic shoulders advocates time-consuming reconstructions and reformations for an accurate assessment of glenoid...
Two important components of a speaker identification system are the feature extraction and the classification tasks. First, features must be robust to noise and they must also be able to provide discriminating information that the classifier can use to determine the speaker's identity. Second, the classifier must take the features that have been extracted from a sentence and label them as corresponding...
Using a machine learning algorithm for a given application often requires tuning design parameters of the classifier to obtain optimal classification performance without overfitting. In this contribution, we present an evolutionary algorithm based approach for multi-objective optimization of the sensitivity and specificity of a v-SVM. The v-SVM is often preferred over the standard C-SVM due to smaller...
We have recently introduced an incremental learning algorithm, Learn++.NSE, designed to learn in nonstationary environments, and has been shown to provide an attractive solution to a number of concept drift problems under different drift scenarios. However, Learn++.NSE relies on error to weigh the classifiers in the ensemble on the most recent data. For balanced class distributions, this approach...
