A modification of the fuzzy backpropagation (FBP) algorithm called QuickFBP algorithm is proposed, where the computation of the net function is significantly quicker. It is proved that the FBP algorithm is of exponential time complexity, while the QuickFBP algorithm is of polynomial time complexity. Convergence conditions of the QuickFBP, resp. the FBP(More)
A web-based tool AirPolTool for air pollution prediction and control in Istanbul is developed. It models the relationship between local meteorological data and air pollution indicators concentrations like SO 2 , PM 10 and CO by using neural networks. AirPolTool presents on the user-friendly website three-days predictions of air pollution(More)
The main Computational Intelligence (CI) models for personalization of interactive web systems are performance and application to personalization of interactive web systems. A taxonomy for personalization of interactive web systems based on CI methods is proposed. It uses two approaches to personalize web-based systems as profile generation and profile(More)
An approach for affective product design using a hybrid of tunable particle swarm optimization (PSO) and Kansei engineering is proposed. Customers' emotive responses to a product are collected using a questionnaire designed on Kansei engineering principles. They are used to create models which can suggest design parameters for the product that may(More)
