Load classification group method

This paper dissertates the implementation of a feedback based content filtering system, which uses VSM (Vector Space Model) and TC3(Text Categorization based on Category Centroid) to create profile, the Cosine Measure to compute the similarity between documents for filtering and user s profile, and Rocchio feedback model to rebuild user s profile.

它采用向量空间模型 ,使用类重心分类算法来形成用户兴趣文件 ,采用余弦算法比较待过滤文档和用户兴趣文件的相似度 ,并使用Rocchio反馈模型来重建用户兴趣文件。

MUSIC algorithm is used to estimate target angles in order to accurately determine the direction and the disto.

为能达到要求的角度分辨率 ,对该阵列应用了多重信号分类法 (MUSIC)进行方位分辨 ,并校正了阵元间互耦对MUSIC算法的影响。

The techniques of MUSIC and MVM are applied to obtain sea echo s direction of arrival (DOA).
