Abstract :
Based on the reduction of entropy, the analysis of the estimation of error bounds is discussed. This estimation is simple in computation and is associated with a scatter matrix of classes. For the case of a large character set, a novel definition of separability of classes is proposed. It is simple in computation and can be used to evaluate error bounds and to choose a subset of features with minimum loss of information
