With the rapid development of witkey website, the amount of witkeys and tasks on the witkey sites is increasing far more quickly than our ability to process it. It is a critical problem needs to be solved for us to accomplish witkeys and tasks rapid matching. To resolve this problem, an available way is the recommender system. This paper analyzes the witkey(More)

—In this brief, the global exponential stability of fuzzy cellular neural networks(FCNNs) with variable coefficients and unbounded delays was investigated. Without assuming the boundedness and differentiability of the activation functions, based on the properties of M-matrix, by constructing vector Lyapunov functions and applying differential inequalities,(More)
