Abstract
When a mixture of different kinds of particles, such as blood, is passed through a particle detector such as a flow cytometer to measure various characteristics of each particle and the measurements of two characteristics are plotted oh a two-dimensional rectangular co-ordinate, for example, the resultant dots tend to part into groups (clusters) corresponding to the kinds of the particles. This invention relates to a method and a device for presuming informations of the position of center of gravity, variances, number of dots and likes of each cluster by learning and, based upon these informations, presuming a specific cluster or category to which each measured particle should belong from the corresponding measurements of the particle, and it intends to execute such information processing by a fuzzy clustering technique using a neural network.
