Development of a User-Friendly Designed Application for Mobile Devices to Display a Torus-type Self-Organizing Map

Abstract

A self-organizing map (SOM) is one of the neural network models to develop a feature map, which visualizes a data structure of the applied patterns. In this article, development of a user-friendly designed application for mobile devices is tried. In order to display a feature map on the screen at that time, several popular touch gestures such as swipe, pinch and tap are introduced for users to make scroll in any directions, magnify its appearance, and provide further information, respectively. Once a prototype is completed successfully on the emulator, it is implemented on the tablet computer. And it is confirmed that it works well as intended in advance.
