چکیده
Neural maps and Learning Vector Quantizer are fundamental paradigms in neural vector quantization based on Hebbian learning. The beginning of this field dates back over twenty years with strong progress in theory and outstanding applications. Their success lies in its robustness and simplicity in application whereas the mathematics beyond is rather difficult. We provide an overview on recent achievements and current trends of ongoing research.

Identifying clusters is an important aspect of data analysis. This paper proposes a noveldata clustering algorithm to increase the clustering accuracy. A novel game theoretic self-organizingmap (NGTSOM ) and neural gas (NG) are used in combination with Competitive Hebbian Learning(CHL) to improve the quality of the map and provide a better vector quantization (VQ) for clusteringdata. Different ...

متن کاملUnderstanding Kohonen Networks
Kohonen neural nets are some kind of competitive nets. The most commonly known variants are the Self-Organizing Maps (SOMs) and the Learning Vector Quantization (LVQ). The former model uses an unsupervized learning, the latter is an e cient classi er. This paper tries to give, in simple words, a clear idea about the basis of competitive neural nets and competitive learning emphasizing on the SO...
متن کاملHierarchical overlapped SOM's for pattern classification
We develop a multilayer overlapped self-organizing maps (SOM's) with limited structure adaptation capabilities, and associated learning scheme for labeled pattern classification applications. The learning algorithm consists of the standard unsupervised SOM learning of synaptic weights as well as the supervised learning vector quantization (LVQ) 2 learning. As higher layer SOM's overlap, the fin...
