This paper proposes an hybrid Artificial Neural Network (ANN) with Self-Organizing Map (SOM) and modified Adaptive Coordinates (AC) for multivariate dimension reduction and data structures exploration. SOM, being a prominent unsupervised learning algorithm, is often used for multivariate data visualization. However, SOM only preserved input space(More)
Historically, Streptococcus pyogenes was a common cause of endocarditis and infected aortic aneurysm. Today, endovascular infections due to this organism have become exceedingly rare. We report the first case of aortic aneurysm infection due to S. pyogenes treated with initial endoluminal repair, review previous reports and discuss current treatment options.
This study proposes a hybrid model of Self-Organizing Map with modified adaptive coordinates (SOM-AC) and Spiking Neural Network (SNN) for multivariate spatial and temporal data visualization and classification. SOM is one of the most prominent unsupervised learning algorithms. Recently, many extensions for SOM have been proposed for temporal processing.(More)
