摘要

推荐系统向其注册用户提供有关新发布电影的到来和重要性的信息。从用户过去的历史中分析用户的追求。本文提出了一个推荐系统,向用户推荐电影的评分。系统的学习阶段接收用户迄今为止的详细信息以及他对这些电影的评分。有了电影的类型及其评级,系统通过贝叶斯、多类分类器、决策树桩树、最佳第一决策树(BFTree)和径向基函数(RBF)等数据挖掘分类器进行训练,并计算分类参数,即真阳性率(TP)、假阳性率(FP)、精度、召回率和平均绝对误差。结果表明,RBF分类器的性能优于其他分类器。本文还着重解决了冷启动影片的问题。获取新版本的类型,并将其推荐给相关用户。使用电影镜头数据集进行实现。

Recommendation system to accomplish user pursuit
Recommendation system provides information about the arrival and importance of a newly released movie to their registered user. The pursuit of the users is analyzed from their past history. In this paper, a recommendation system is proposed to recommend rating of the movie to the users. The learning phase of the system takes in the user particulars about the user till-date and his rating towards those movies. Having the Genre of the movie and its rating, the system is trained by data mining classifiers like Bayesian, Multiclass Classifier, Decision Stump Tree, Best First Decision Tree(BFTree) and Radial Basis Function(RBF) and the classification parameters i.e. True Positive rates(TP), False Positive rates(FP), Precision, Recall and Mean Absolute Error are computed. It has been concluded that the RBF classifier performs better than the other classifiers. This paper also focuses to address the problem of cold start movie. The genre of the new release is obtained and it's recommended to the corresponding user, those who are closely correlated. Implementations are carried out using movie lens datasets.
