Re: [iot-wg] Eclipse Proposal - Matrix Algorithms

Hi Philip,

Wrong mailing list? :)

Hi folks,

does it make sense to file a new Eclipse Proposals "Matrix Algorithms"
under the umbrella of the Science working group?

We have dozens of algorithms in ChemClipse/OpenChrom which we would like
to migrate to a separate project. The goal is, that they can be reused
more easily in other projects. I assume

Diamond Light Source
Oak Ridge

are facing the same problem. At the moment, these algorithms are part of
ChemClipse, DAWNSci, deeplearning4j ... and to use them, you have to
clone the complete project even if you only need a certain algorithm. We
could provide the following algorithms (implementations) in Java:

SVD (Singular Value Decomposition)
NIPALS (Non-linear Iterative Partial Least Squares)
OPLS (Orthogonal Projections to Latent Structures)

Currently, we are working on:

MCR-AR (Multivariate Curve Resolution - Alternating Regression)

In the future, we are interested to implement:

PARAFAC2 (Parallel Factor Analysis 2)
TCC (Tucker's Congruence Coefficient)

Java isn't that strong in matrix operations, though we could use matrix
libraries and/or create the algorithms in a way that different matrix
libraries (Java, C, ...) can be used, e.g.:

ND4J (http://nd4j.org)
Eclipse January (https://www.eclipse.org/january)
EJML (http://ejml.org)
OpenBLAS (https://www.openblas.net)

In my opinion, we should have a dependency to Apache Commons Math and
setup the project in an encapsulated way, similar as SWTChart for
plotting charts (it requires only double[] arrays to plot the data).


What's your opinion?
Feedback is highly appreciated.
