  A semi-supervised Partial Membership Latent Dirichlet Allocation approach is
developed for hyperspectral unmixing and endmember estimation while accounting
for spectral variability and spatial information. Partial Membership Latent
Dirichlet Allocation is an effective approach for spectral unmixing while
representing spectral variability and leveraging spatial information. In this
work, we extend Partial Membership Latent Dirichlet Allocation to incorporate
any available (imprecise) label information to help guide unmixing.
Experimental results on two hyperspectral datasets show that the proposed
semi-supervised PM-LDA can yield improved hyperspectral unmixing and endmember
estimation results.
