Cannot scale data with encog -


currently i'm trying scale data file (train.nn) using encog 3, data file looks (this simplified example, in real file, have 249 features each sample sp):

1,0,1,2,sp 4,5,6,1,sp

and code scaling:

file rawfile = new file(mydir, "train.nn"); file scaledfile = new file(mydir, "scaledtrain.nn"); encoganalyst analyst = new encoganalyst();  analystnormalizecsv norm = new analystnormalizecsv(); norm.analyze(rawfile, true, csvformat.english, analyst); norm.setproduceoutputheaders(false); norm.normalize(scaledfile);

but got error:

exception in thread "main" org.encog.app.analyst.analysterror: multiple fields named: 1     @ org.encog.app.analyst.util.csvheaders.validatesamename(csvheaders.java:292)     @ org.encog.app.analyst.util.csvheaders.init(csvheaders.java:270)     @ org.encog.app.analyst.util.csvheaders.<init>(csvheaders.java:146)     @ org.encog.app.analyst.csv.normalize.analystnormalizecsv.analyze(analystnormalizecsv.java:147)

i don't know why complained this.... can show me did wrong here?
thank much.
p/s: looked @ this tutorial . not handy me since defined each field (feature) manually, bad, since in case have 249 features each sample.

you can set loop this:

int fieldcount = 249; inputfieldcsv[] infields = new inputfieldcsv[fieldcount];  int = 0; while (i < fieldcount) {      norm.addinputfield(infields[i] = new inputfieldcsv(true, rawfile, i));     i++; }

then set further loops rest of code see same line repeated over. (code not tested...)
