A Multi-Agent System to Assist with Property Valuation Using Heterogeneous Ensembles of Fuzzy Models
نویسندگان
چکیده
The multi-agent system for real estate appraisals MAREA was extended to include aggregating agents, which are equipped with heuristic optimization algorithms and can create heterogeneous ensemble models, was presented in the paper. The major part of the study was devoted to investigate the predictive accuracy of heterogeneous ensembles comprising fuzzy models and to compare them with homogenous bagging ensembles. Six optimization heuristics including genetic, tabu search, simulated annealing, minimum average and random algorithms were implemented and applied to obtain the best ensembles for different number of fuzzy models.

متن کاملAdaptive Distributed Consensus Control for a Class of Heterogeneous and Uncertain Nonlinear Multi-Agent Systems
This paper has been devoted to the design of a distributed consensus control for a class of uncertain nonlinear multi-agent systems in the strict-feedback form. The communication between the agents has been described by a directed graph. Radial-basis function neural networks have been used for the approximation of the uncertain and heterogeneous dynamics of the followers as well as the effect o...
