Bayesian Markov-chain Monte Carlo (McMC) techniques are increasingly being used in geophysical estimation of hydrogeologic processes due to their ability to produce multiple estimates that enable comprehensive assessment of uncertainty. Standard McMC sampling methods can, however, become computationally intractable for spatially distributed, high-d...

Hyperspectral unmixing, aiming to estimate the fractional abundances of pure spectral signatures in each mixed pixel, has attracted considerable attention in analyzing hyperspectral images. Plenty of sparse unmixing methods have been proposed in the literature that achieved promising performance. However, many of these methods overlook the latent g...

The contribution of the thesis is threefold. The first Problem is computing the discriminant, when the system’s dimension varies. Thus solving polynomial equations and systems by exploiting the structure and sparseness of them have been studied. Specifically, closed formulas for the degree of the sparse (mixed) discriminant and the sparse resultant...
