New Topics from Recent Interactive Evolutionary Computation Researches

Abstract

First, we review wide varieties of IEC applications. They include artistic applications such as generating computer graphics, music, and editorial design, acoustic and image signal processing, hearing aid fitting, data mining, architectural design, virtual reality, and others.

Secondly, we introduce new type of IEC applications. Major IEC applications are optimizing target systems and creating graphics, images, shapes, sounds, vibrations, and others. We introduce two new types of IEC applications. The first one is measuring human characteristics. IEC is an optimization method based on human subjective evaluation. Likely reverse engineering, we may measure the evaluation characteristics or mental conditions of an IEC user by analyzing the outputs from the target system optimized by the user. The second one is extension of IEC evaluation. Usually IEC optimizes a target system based on IEC user’s subjective evaluation, i.e. psychological evaluation. We may extend the evaluation from psychological one to physiological one. We show the framework of the extended IEC.

Thirdly, we overview the researches that try to reduce IEC user fatigue and show our latest research in this area. Several approaches have been proposed to reduce IEC user’s fatigue; some of them are improving input/output interface, accelerating EC search, allowing human intervention into EC search, estimating human evaluations, and others. Here, we introduce our latest research and show our view.
