讨论了自组织映射网络(self-organizing map,SOM)的发展与应用进展情况。首先介绍了自组织映射网络的产生、发展概况,网络的原理、基本结构和算法,网络的应用现状以及最新的研究进展情况。基本的自组织映射算法在实际应用中存在着一定的缺陷,对此着重介绍了近年来自组织映射网络的各种改进方案,以及目前在化学化工领域中的应用情况。最后提出了自组织映射网络研究中仍然存在的问题,并对其在化学化工领域中的应用发展前景做了展望。
The progress and application of self-organizing map (SOM) are discussed. Firstly, the author introduces the generation and development of self-organizing mapping network, the principle of network, the basic structure and algorithm, the application status of network and the latest research progress. The basic self-organizing mapping algorithm has some shortcomings in practical application. In this paper, various improvements of self-organizing mapping network in recent years are introduced, and the applications in the field of chemical chemistry are introduced. Finally, some problems that still exist in the research of self-organizing mapping network are put forward, and the prospect of its application and development in the field of chemical chemistry is also prospected.
