Independent components in spectroscopic analysis of complex mixtures
Yulia B. Monakhova, Sergey A. Astakhov, Alexander Kraskov +1
We applied two methods of "blind" spectral decomposition (MILCA and SNICA) to quantitative and qualitative analysis of UV absorption spectra of several non-trivial mixture types. B…

Monte Carlo Algorithm for Least Dependent Non-Negative Mixture Decomposition
Sergey A. Astakhov, Harald Stögbauer, Alexander Kraskov +1
We propose a simulated annealing algorithm (called SNICA for "stochastic non-negative independent component analysis") for blind decomposition of linear mixtures of non-negative so…
