Abstract
In our daily life, many recommendation systems are designed based on collaborative filtering algorithm. For example, video recommendations, shopping recommendations, music recommendations, and so on. However, the traditional collaborative filtering algorithm has problems such as low recommendation accuracy and poor real-time performance. In this paper, an enhanced collaborative filtering algorithm considering the relevance factor and time factor is proposed to improve the accuracy and timeliness of recommendations. Meantime, the average absolute error is utilized as an indicator to measure the recommended effect. Simulations are given to prove the effeteness of the proposed algorithm.
