Welcome to Ken'ichiro Tanaka's home page. I am a professor at Institute of Science Tokyo.

Research

My research interest is in numerical analysis and computational methods in science and engineering.

• Function approximation, numerical integration, and their application to equations
    ◦ Double-exponential (DE) Sinc methods
    ◦ Kernel quadrature / interpolation
• Mathematical optimization
    ◦ Conditional gradient methods (for sampling)
    ◦ Gradient descent methods (for sampling)
• Numerical methods for economics and finance
• Numerical computation with guaranteed accuracy

Please see my research and publication list for more details.
