In order to predict personalized quential patterns,the long-term ur prefer-

for both personalization and quential transitions.In this paper,a IFNR model

Recommendation system has become a basic function of the online application nowadays,which can recommend products or rvices that meet ur’s preferences. Recommendation system can discover the internal relationship between urs and items according to the interaction between urs and items[1].The goal of item recom-mendation is to recommend a specific list of items to each ur.Most existing methods do not consider the recent behavior of urs but recommend items bad on the whole purcha history of urs.Predicting the ur’s recent behavior requires recommen-dation bad on the time quence of the items purchad.
In order to reasonably predict the ur’s personalized preferences,it is necessary to combine the ur’s long-term preferences with short-term preferences.The long-term preferences means that the ur’s preferences are inherently have not changed with time.For example,if the ur prefers a certai
n brand of goods,the purcha behavior of the brand’s goods will not change with time.Short-term preferences means that the
