Thanks,as you can see that,from second item,the classification results actually opposite against to each other in two modes
TRAIN output:[[  7.2314,  -9.7634], [-11.1361,  15.7153],  [ -6.0605,   7.8842],  [ -7.5571,  10.5594]]
EVAL   output:[[  9.7397, -12.8771],[  2.3994,  -3.3750], [  5.1334,  -6.9638], [  9.0693, -11.9809]]

and How can I use this evaluation result to evaluate the model?
