Abstract(in English) | This paper studies how the difference of sigmoidal function′s po larity effects the convergence properties of the error back propagation learning.From simulation results,the convergence properties are summarized as follows.First,in the case of large sized networks,the bipolar sigmoid is superior in both convergence ratios and learning speeds to the unipolar one,and gives good convergence for wider range of initial values than the latter.Then, the convergence properties due to the unipolar sigmoid are apt to depend on the learning rate more than those due to the bipolar one. Finally,in the case of small sized networks,the initial values giving good convergence are smaller for the unipolar sigmoid than for the bipolar one. |
