Furthermore, we compare ALDIP and ALDIP-SSTV with other state-of-the-art methods on two synthetic and three real-world HSI datasets.

In this paper, we construct a parametric estimator for the expected shortfall based on a new family of densities, which we call the Asymmetric Power Distribution (APD). The APD family extends the Generalized Power Distribution to cases where the data exhibits asymmetry.
