I'm working with neural networks and I've implemented the following architecture using keras
with tensorflow
backend:
For training, I'll give some labels in the layer labels_vector
, this vector can have int32
values (ie: 0 could be a label). For the testing phase, I need to just ignore this input layer, if I set it to 0
results could be wrong since I've trained with labels that can be equal to 0
vector. Is there a way to simply ignore or disable this layer on the prediction phase? Thanks in advance.
How to ignore some input layer ?
You can't . Keras cannot just ignore an input layer as the output depends on it.
One solution to get nearly what you want is to define a custom label in your training data to be the null value. Your network will learn to ignore it if it feels that it is not an important feature.
If labels_vector
is a vector of categorical labels, use one-hot encoding instead of integer encoding . integer encoding assumes that there is a natural ordered relationship between each label which is wrong.
