| Abstract(in English) | We propose Hierarchical Learning Vector Quantization(HLVQ) as rough classification method for handwritten characters. HLVQ divides categories in feature space hierarchically in learning procedure. HLVQ adds neurons hierarchically and makes tree whose nodes are neurons. The feature space is divided by a few codebook vectors in each layer. The adjacent feature spaces overlap each other near the borders using window HLVQ possesses both classification speed and accuracy due to the hierarchical architecture and the overlapping technique. By using secondary classification with plural codebook vector for each category under HLVQ, the speed and accuracy of classification by proposed method are higher than that by using average vectors. |
