Under the guidance of DPRIF integrating strategy, we set up an integreted SOFM-SVM model. Then we analyzed and optimized the model from the aspects of operating mechanism, data interface and function expandedness. The PCA method was introduced to reduce dimensionality and extract features, then to strengthen the clustering explanation; defined a CMI index, to ascertain the most effective or the best clustering number; A new Anti-NO algorithm was proposed to recognize and to filter the suspecious data in the sample; The medium result of SVM model was used to extract the borderline datas between two classified groups. This research compensated for the achievements of data recognition including pattern data, noises data and borderline data.
在DPRIF整合策略指导下构建了一个整合的SOFM-SVM模型,对该模型从运作机制、数据接口、功能扩展几个方面进行分析和改进:引入PCA方法进行数据降维和特征提取,用以加强聚类解释;结合统计聚类中的聚类误差概念定义一个聚类数有效性指标,利用SOFM算法中间结果进行指标求解,以筛选出有效或最佳聚类数;提出一种新的噪声识别算法用于对样本中的异常数据进行甄别和过滤;利用SVM模型的中间结果提取分类边界数据;进一步充实了包括模式类、噪声集和边界在内的模式识别成果。
