英文摘要the input data of collaborative filtering, also known as recommendation system, are usually sparse and noisy. in addition, in many cases the data are time-variant and have obvious periodic property. in this paper, we take the two characteristics into account. to utilize the time-variant and periodic properties, we describe the data as a three-order tensor and then formulate the collaborative filtering as a problem of probabilistic tensor decomposition with a time-periodical constraint. the robustness is achieved by employing tsallis divergence to describe the objective function and q-em algorithm to find the optimal solution. the proposed method is demonstrated on movie recommendation. experimental results on two netflix and movielens databases show the superiority of the proposed method.
