[Jboost-users] BadAttException running JBoost

[Rodrigo P. <piz...@gm...>]

Hi,

i have a Exception "BadAttException" while running JBoost.

--------------------------

The train file is like:

neoplasia maligna de labio superior externa , c000;
neoplasia maligna de labio superior borde vermellon sai , c000;
neoplasia maligna de labio superior externa trastorno , c000;
neoplasia maligna del labio superior area del bermellon trastorno , =20
c000;
tumor maligno de ddel borde bermellon del labio superior trastorno , =20
c000;
...
...

And the spec file is like:

exampleTerminator=3D;
attributeTerminator=3D,
maxBadExa=3D2000

diagnostico text
labels (c000,c001,c002,c003,c004,c005,c006,c009, ... ,d487,d489)

(it's resumed)

I have changed the maxBadExample parametrer for some values between 0 =20=

and 2000 and I still get similar errors. The jboost execution is fine =20=

with the demo examples.

What can be happening?
What means "maxBadExa" parameter?


Many thanks beforehand!!!
