In this paper, an approach based on silhouette index (SI) and improved gravitational search algorithm (IGSA) is presented to deal with T-S model identification problem. Clustering algorithm employing SI and IGSA is introduced for structure identification. The SI considers both the intra-cluster cohesion and the inter-cluster separation which can highly assess the accuracy of clustering. One cluster...
Construction project cost forecasting is a key procedure to the mangement project. An accurate forecast can support the investment decision and ensure the project's feasible at the minimal cost. So reasonable determining and controlling the project cost become the most important task in the budget management of the construction project. A novel regression technique, called Support Vector Machines...
