在较新版本的scikit-learn库中,jaccard_similarity_score函数已经被重命名或移除。从scikit-learn 0.24版本开始,这个函数已经被重命名为jaccard_score。因此,如果你尝试从sklearn.metrics导入jaccard_similarity_score,可能会遇到导入错误。 确认用户安装的scikit-learn库版本: 为了确认你安装的scikit-learn版本,你可以使用以...
jaccard_score solves the problem of syntax error but, it produces a different value than that of jaccard_similarity_score. Can anyone suggest what are the parameters that are needed to be tuned in jaccard_score() to get those values which are obtained by using jaccard_similarity_score.Saanidhy...

So that a novel method called prospective Jaccard similarity measure (PJSM) was proposed. Its novelty is to overcome the data sparsity issues in CFRS method as well as the conventional algorithmic method limitations. MovieLense dataset is extracted and applied for an implementation. Research ...
