This paper examines two vector quantization algorithms which can combine the tasks of compression and classiication: Bayes risk weighted vector quantization (BRVQ) proposed by Oehler et al., and Optimized Learning Vector Quantization 1 (OLVQ1) proposed by Kohonen et al. BRVQ uses a parameter to control the tradeoo between compression and clas-siication. BRVQ performance is studied for a range o...
