The proposed method does not solve the differential equations, learns the genetic networks using Product-Unit-based-Neural-Network (PUNN) and estimates the S-system model of genetic networks which describes the differential equations. The experimental results show the proposal method is 160 times faster than the previous method which estimated S-system model of genetic networks while maintaining equivalent performance to the previous method.}, pages = {74--87}, title = {Product unit based neural networksを用いた遺伝子ネットワークのS-systemモデル推定手法の提案}, volume = {1}, year = {2008} }
