Rule of thumb for picking k hypothesis

I’m still experimenting with finding the lowest usable k value for the
entire set of, currently, 73 characters
Include some special characters
To quickly test if the eigenimagespace is useable

The images should be output and recognizable
OCR using eigen images

It works, but is rather sloooooooooooow. Did I mention that it works:
“Men are b0rn anl remain tree anl equaI in rigntsL s0ciaI listincti0ns
mav be t0unlel 0nIv up0n tne generaI g00lL Ine aim 0t aII p0IiticaI
ass0ciai0n is tne preseWai0n 0t tne nauraI anl impIscriptibIe rignts 0t
manL Inese rignts are Iibecv1 pr0pecv1 securitv1 anl Isistance t0
0ppressi0nL”
Trim the eigen values
Individual named files
Print status info
Add smaller test image
Print status info
Remove dead code
Add more status info
Reduce dimensionality from 1024 to 256

Check improved speed vs decreased accuracy (which isn’t that good yet
anyhow) — From “M.n ar. b.rn anl r.main tr.. anl .quaI in rigntsL
s.ciaI” to “V.n ar! b!rn an5 r!ma.n Tr!! an5 !quaI .n r.gntGL S!C.aI”
Added another, worse, distance measure
Prepare to experiment with imagespace means

“M.n are b.rn an5 remain Tree an5 e;uaI in rigntGL S.CiaI” becomes “Ven
ar! b!rn an5 r!main Tr!! an5 !qua. in rigntGL S!Cia.”
Cosine similarity seems to be the best measure

“Men are b!rn and remain Tree and e;ua. in rightGL S!Cia.”
“Men are born and remain Free and equal in rights. Social”
