Two PhD students from the University of Macau's (UM) Faculty of Science and Technology, namely Ren Chang'e and Zhang Tong, recently received the sole Best Conference Paper Award and one of the two Best Student Paper Outstanding Awards, respectively, at the 2015 International Conference on Fuzzy Theory and Its Applications (iFuzzy2015). More than 120 papers were presented at this year's conference.

Ren's paper, titled 'Adaptive Consensus Control for Nonlinear Multi-agent Systems', concerns a new adaptive consensus control algorithm for multi-agent systems with heterogeneous nonlinear dynamics. The fuzzy neural networks and adaptive distributed algorithm are applied to deal with unknown nonlinear dynamics. The new adaptive consensus control algorithm not only allows multi-agent systems to reach leader-following consensus simply based on local information from its neighbour, but it also reduces online learning time and computation burden. Ren's paper is co-authored with Dr Chen Long from the FST and FST Dean Prof Philip Chen.

Zhang's paper, titled 'A Novel Image Segmentation Approach Based on Spatial Shadowed Fuzzy C-means and I-Ching Operators', concerns a novel clustering algorithm for image segmentation, which is based on I-Ching operators and shadowed FCM. A comparison of global optimisation ability and performance shows that the new algorithm achieves better accuracy than other traditional approaches. Zhang's paper has been recommended for publication in the International Journal of Fuzzy Systems (IJFS), a journal indexed in the SCI-Expanded. The paper is co-authored with Dr Chen Long and Prof Philip Chen. It was one of the nine papers that made the final list of best student papers.

澳門大學科技學院兩名博士生於“二○一五年度國際模糊理論及應用大會”上發表的論文備受矚目,澳大博士生任長娥的論文被大會評為唯一一篇“最優會議論文”;而另一名博士生張通的論文被大會評為僅有的兩篇“最優學生論文傑出獎”之一,成績優異,顯示出澳大論文的研究水平卓越。

任長娥的論文以“非線性多智能體系統的自適應一致控制"為題,為含有不同非線性動態的多智能體系統提出了一種新的自適應一致算法。在此算法中,模糊神經網絡系統和自適應算法被應用於處理未知的非線性動態。此算法在使多智能體系統在達到領航協同的同時亦能減少計算量和在線學習的時間。該論文由任長娥、澳大科技學院陳龍博士和院長陳俊龍教授共同撰寫。

張通的論文以“一種新穎的基於易經算子和空間陰影模糊C均值聚類的圖像分割算法的研究”為題,提出了一種基於易經算子和空間陰影FCM的聚類算法,並將之應用在圖像分割領域中。根據所提出的算法的全局收斂性和在對比試驗中的結果比較,該文提出的算法在圖像分割領域擁有更高的準確率。這篇文章還被推薦到 SCI檢索的《International Journal of Fuzzy Systems (IJFS)》雜誌中發表。該論文在陳龍博士和陳俊龍教授指導下完成,且在9篇入圍的最優學生論文中脫穎而出。

今屆國際模糊理論及應用大會有超過120篇論文發表,旨在於提升與擴展模糊理論之廣泛應用。
