Chemometrics Needs #16

Closed Gondee closed 8 years ago

Gondee commented 8 years ago

Chemometric Needs: -Make the number of latent vectors static (2 so that we get 2 axes for a 2D graph) -Save the model in the file system (pca offers the export function to produce an object which we can put in a JSON file or the like) -Load the model from the file system -Store/Load scan files

SIde note: what is in a training scan file -the absorbances -the concentrations (must know for data to have value) -Perhaps a qualitative name (useful for PCA, but not essential) -tags indicating the name of each material in the sample Example: "Bad Substance",[0.5, 0.5], [Evil A, Evil B], [3.3, 5.4, 9.1............]

Accomplished -Rudimentary load model done -Rudimentary store/load scan files done

To Do -make PCACompress available to get points for chart -make measured available to get last point for chart -verify functionality of pca/database (the big one) -verify Pls (experiencing weird NaNs)

I have determined that an entire column of zeroes produces the weird NaNs.

Damn. I have full load save unpushed. Ring dunks tonight, so I'll push tomorrow
