Low accuracy
1 I trained some model and the result is bad
2 i don't konw what's the use of the 'Undefined' class, in neural network, it makes the model have one more output, which i think influence the final result.

this result is chen's 3DCNN, I use 5% of samples. it predict many samples to the 'Undefined' class. thanks.
