The third and last of the series on unmixing using NMF is now posted at
https://dblog.vitumbre.tech/dart/unmixing-using-nmf-part-3-assessing-accuracy-of-end-members/
Part 3 illustrates the variability of results that can occur when repeatedly unmixing the same data set, and presents approaches to addressing the resultant uncertainty.

Part 2 of this series on unmixing is now available:
https://dblog.vitumbre.tech/dart/unmixing-using-nmf-part-2-evaluating-the-number-of-end-members/
Part 2 addresses the challenge of deciding how many end members are in a data set, recommends algorithms for Python, Julia, and R, and illustrates how several factors affect that determination.

I just posted part 1 of a 3-part series on unmixing of data sets using non-negative matrix factorization.
Part 1 contains implementations in Python, Julia, and R, and includes an assessment of the relative accuracy of these implementations.
Parts 2 and 3 will follow shortly, and will contain more detail on the identification of, and accurate characterization of, unmixing end members.

Data sets that can be represented as a matrix of cases (rows) and variables (columns) often have structure within them that is not immediately apparent. There are a number of techniques for identifying and characterizing hidden structure in data sets. Unmixing is a method that is appropriate when the data
