Profile My specialty is applications of evolutionary computation algorithms. Evolutionary computation algorithms are often applied for solving optimization problems. I have worked on various problems in the different fields as follows.
- Automatic music composition adapted to personal sensibility
- Generation of a corporate sound logo
- Generation of a melody for musicians' creative activities
- Predicting return date of rental unit houses
- Reduction of both cost and CO2 emissions in the vehicle routing and cargo allocation problem
- Tailor-made selection of policy measures for households
- Evaluation of household micro-data for land-use microsimulation models
- Modifiable attribute cell problem in population synthesis for land-use microsimulation
Research Field(Keyword & Summary)
  1. Symbiotic Evolution

    Many types of genetic algorithm have been proposed. Symbiotic evolution was proposed for forming Neural Networks. It maintains two separate populations: a population of partial solutions and a population of whole solutions, and results in a fast, efficient genetic search and prevents convergence to suboptimal solutions. In my research, its effectiveness had been demonstrated in not only Neural Networks but also Inductive Logic Programming, generating decision trees.

  2. Automatic music composition

    We develop automatic systems that compose music adapted to personal sensibility. These systems induce a personal sensibility model by using a listener’s emotional impressions of music and compose music based on the model using evolutionary computation algorithms. These systems are also used to support professional musicians' creative activities.
