Mixture of local principal component analysis (PCA) has attractedattention due to a number of benefits over global PCA. The performance ofa mixture model usually depends on the data partition and local linearfitting. In this paper, we propose a mixture model which has theproperties of optimal data partition and robust local fitting. Datapartition is realized by a soft competition algorithm called neural ’gas‘and robust local linear fitting is approached by a nonlinear extension ofPCA learning algorithm. Based on this mixture model, we describe a modularclassification scheme for handwritten digit recognition, in which eachmodule or network models the manifold of one of ten digit classes.Experiments demonstrate a very high recognition rate.
