This paper makes a comprehensive introduction to collaborative filtering aiming to facilitate readers to understand this field. Firstly the research background is introduced, including mainstream collaborative filtering applications, research conferences and journals. Then this paper briefly describes the current generation of collaborative filtering that are usually classified into the following...
Most designs for heading controller adopted Taylor linearization technique and neglected its nonlinear factors. For this reason, the accuracy of heading control for autonomous underwater vehicle (AUV) was lower. In order to solve this problem and enhance the accuracy, robustness and stability for heading control system, a nonlinear model of AUV in horizontal plane was established, which include uncertainties...
