How To Use

Hard code your data in the main function.

function main()# Training sample preparation. # Please, hard code your data into the following matrix.# Enjoy your life with Julia...

X = [1 1; -1 -1; 0.5 0.5; 0.5 -0.5; -0.5 0.5; -0.1 -0.1] y = [1, 1, 1 -1, -1, -1]

About 150 lines for SMO

# Optimization rootine

numChanged = 0

examineAll = truewhile numChanged > 0 || examineAll numChanged = 0

if examineAll for i in 1:CONST.sampleSize numChanged += examineExample(params, y, G, errorCache, i, CONST)

end else for i in 1:CONST.sampleSize if α[i] > 0 && α[i] < CONST.C numChanged += examineExample(params, y, G, errorCache, i, CONST)

end end end if examineAll examineAll = false elseif numChanged == 0

examineAll = true endend
