h2o.deepfeatures | R Documentation |
Extract the non-linear feature from an H2O data set using an H2O deep learning model.
h2o.deepfeatures(object, data, layer)
object |
An H2OModel object that represents the deep learning model to be used for feature extraction. |
data |
An H2OFrame object. |
layer |
Index (integer) of the hidden layer to extract |
Returns an H2OFrame object with as many features as the number of units in the hidden layer of the specified index.
h2o.deeplearning
for making H2O Deep Learning models.
## Not run:

hidden = c(100, 200), epochs = 5)
