Geometrical and computational aspects of Spectral Support Estimation for novelty detection

摘要

In this paper we discuss the Spectral Support Estimation algorithm (De Vito et al., 2010) by analyzing its geometrical and computational properties. The estimator is non-parametric and the model selection depends on three parameters whose role is clarified by simulations on a two-dimensional space. The performance of the algorithm for novelty detection is tested and compared with its main competitors on a collection of real benchmark datasets of different sizes and types.
