​Bilinear problems often arise where observed data is expressed as the linear sum of products of two unknown variables. We do research on bilinear problems and provide professional services in three specific areas: (1) Research and Development, (2) Applications, and (3) Training.

research and development

iGBu has developed a number of advanced bilinear models and tools. With our broad experience and specialty in developing advanced bilinear models, iGBu provides professional services to clients to develop their own models or tools suited to their specific needs.


iGBu focuses on three application areas: analytical chemistry, environmental quality analysis , and information security. We utilize our advanced models and tools to resolve our client’s bilinear problems.


iGBu offers short-course training sessions. Clients can either participate in our annual iGBu training course, or opt for off-site training at one of their own facilities.
