| 摘 要： | 分析了ROCK算法的优点和缺点,ROCK算法优点是容易聚类Mushroom等分类属性数据集;缺点是这种算法的相似度函式sim是基于领域专家的直觉.改进的ROCK算法采用Jaccard系数计算相似度,根据相似度的值越大表示对象越相似进行聚类,得到聚类结果,从而实现用户的个性化推荐.

| Abstract: | This paper analyzes the merits and demerits of the ROCK algorithm,indicating that the merits of ROCK are easy to cluster categorical database such as Mushroom,and the demerits are that the similarity formula sim of this algorithm depends on the intuition of domain experts.The improved ROCK gets the result of clustering by calculating the similarity using Jaccard coefficient based on the reason that the bigger figure of the similarity is,the more similar the object is.Then we can implement personality recomm... |
