Abstract: The peculiarity factor（PF）,an important feature of data and obtained by accumulating differences between data,is a core concept of peculiarity-oriented mining（POM）.But it meets a higher computational time complexity for any algorithm.A sampled approach was first suggested to define PF through analyzing current versions of PF and computational complexities of algorithms to compute it.A sampled PF（SPF）was proposed to meet real-time requirement and a SPF-outlier detection algorithm was given.Experi... More
