| 中文摘要: |
| 本文将模式识别中的特征选择方法用于水下目标特征的优化选择。用距离测度作为选择的准则,对提取的三类舰船噪声的高维组合特征进行自动选择,并用10-折交叉验证方法对选择出的特征子集进行评估,分析结果说明该方法能从原始的特征集中选择出有利于分类的特征子集,提高了水下目标分类的正确率。 |
| 英文摘要: |
| In this paper, feature selection technique is introduced in optimizing the features of underwater targets. According to the distance measure, the feature subset is automatically selected by the feature selection technique. And the selected feature subsets are evaluated by the 10-folds cross validation. Analysis of experimental results for three different classes of targets shows that the feature selection technique is feasible to select feature subset of the underwater targets, which is useful for the classification task. At the same time, this technique improves the correctness of the classifier. |
