Taguchi methods – An approach to design of experiments developed by Genichi Taguchi that uses a quadratic loss function; also called robust design.
Dr. Genichi Taguchi developed a practical approach for designing quality into products and processes. His methodology recognized that quality should not be defined as simply within or not within specifications, so he created a simple quadratic loss function to measure quality. The two figures below contrast the typical 0-1 loss function used in quality with the Taguchi quadratic loss function.
