摘要：
This paper presents two dimensionality reduction methods, mixtures of factor analyzers (MFA) and deep mixtures of factor analyzers (DMFA), for classification of hyperspectral image (HSI). DMFA consists of two layers of MFA and can extract more information from HSI than MFA can. The performance of MFA and DMFA dimensionality reduction methods for classification using real HSI is evaluated in this paper. Experimental results are compared to conventional methods like probabilistic principal component analysis and factor analysis and it is shown that MFA and DMFA give better results.
