This paper describes a composition of learning patterns based on the visualization of a Spherical SOM for improving the performance of image analysis using the Subspace classifier. We have applied the Subspace classifier to image analysis because it has fewer parameters and higher performance. Then we have experienced that the selection of features and learning patterns influence greatly the classification performance through examinations. The Spherical SOM has no border in the array of nodes and eliminates the Border effect problem. Comparing the performance of the image analysis, we show that visualization of the Spherical SOM allows the composition of learning patterns to improve more performance and degree of its reliability than those without the composition.
