An independent component analysis (ICA) has received much attention in the fields of pattern recognition, such as face, fingerprint, figure, character, or number recognition. FastICA is an efficient and popular algorithm for ICA, and an improved algorithm is available for character recognition. In order to increase the rate of recognition, the appropriate setting of parameter or base number is indispensable. We investigate the effects of a change in base number on recognition rate to clarify the index for determining the number. As a result, we confirmed that recognition error rate tends to decrease in case the number is 3, 4, or 5.
