WebJul 10, 2009 · Self-modeling curve resolution (SMCR) was introduced in 1971 by Lawton and Sylvestre for decomposing a bilinear two-component spectroscopic data matrix into physically interpretable profiles, i.e. concentration profiles and spectra, using the minimal constraint of nonnegativity for concentrations and absorbances. Unfortunately, the … WebJul 16, 2013 · In this work, we have returned to the resolution theorems by using visualization tools for calculation and demonstration the area of feasible solutions in a simulated three component system. The effect of selectivity and local rank constraints on rotational ambiguity in the results of self modeling curve resolution methods is the focus.

WebHistory. In chemometrics non-negative matrix factorization has a long history under the name "self modeling curve resolution". In this framework the vectors in the right matrix are continuous curves rather than discrete vectors. Also early work on non-negative matrix factorizations was performed by a Finnish group of researchers in the 1990s under the … WebJul 22, 2024 · On the other hand, for such data matrices, Borgen-Rajkó self-modeling curve resolution (SMCR) techniques reveal all possible solutions analytically under the minimal assumption.
