In this article, we propose batch-type learning vector quantization (LVQ) segmentation techniques for the magnetic resonance (MR) images. Magnetic resonance imaging (MRI) segmentation is an important technique to differentiate abnormal and normal tissues in MR image data. The proposed LVQ segmentation techniques are compared with the generalized Kohonen's competitive learning (GKCL) methods, wh...

Learning vector quantization (LVQ) schemes constitute intuitive, powerful classification heuristics with numerous successful applications but, so far, limited theoretical background. We study LVQ rigorously within a simplifying model situation: two competing prototypes are trained from a sequence of examples drawn from a mixture of Gaussians. Concepts from statistical physics and the theory of ...

In this paper several neural network classiication algorithms have been applied to a real-world data case of electron microscopy image classiication in which it was known a priori the existence of two diierentiated views of the same specimen. Using several labeled sets as a reference, the parameters and architecture of the classiier (both LVQ trained codebooks and BP trained neural-nets) were o...

Neuro-fuzzy approach have attracted considerable attention in the computational intelligence and segmentation algorithms have been increasingly in developed in improving the accuracy of medical diagnosis. Fuzzy set attempts to represent the human perception whereas neural network attempt to emulate the architecture and information representation scheme of human brain. In this paper a comparativ...

In image classification, there are no labeled training instances for some classes, which therefore called unseen classes or test classes. To classify these zero-shot learning (ZSL) was developed, typically attempts to learn a mapping from the (visual) feature space semantic in represented by list of semantically meaningful attributes. However, fact that this is learned without using affects per...

Input feature ranking and selection represent a necessary preprocessing stage in classification, especially when one is required to manage large quantities of data. We introduce a weighted LVQ algorithm, called Energy Relevance LVQ (ERLVQ), based on Onicescu’s informational energy [10]. ERLVQ is an incremental learning algorithm for supervised classification and feature ranking.
