摘要

In collaborative filtering, the stochastic gradient descent (SGD) method is used to determine the latent features used in producing a non-negative N x M matrix of user-item ratings. The method is commonly used because it is straightforward in implementation and has a relatively fast running time. In this paper, we propose an artificial immune system approach to matrix factorization (AISMF) to optimise the latent features during the learning process. Artificial immune systems have the advantage of being dynamic, adaptive and able to learn an antigen in a few cycles. Therefore, they are well suited for the collaborative filtering of recommender systems.
