“““Contains a model definition for AlexNet.
This work was first described in:
ImageNet Classification with Deep Convolutional Neural Networks
Alex Krizhevsky Ilya Sutskever and Geoffrey E. Hinton
and later refined in:
One weird trick for parallelizing convolutional neural networks
Alex Krizhevsky 2014
Here we provide the implementation proposed in “One weird trick“ and not
“ImageNet Classification“ as per the paper the LRN layers have been removed.
Usage:
with slim.arg_scope(alexnet.alexnet_v2_arg_scope()):
outputs end_points = alexnet.alexnet_v2(inputs)

Described in: http://arxiv.org/pdf/1404.5997v2.pdf
Parameters from:
github.com/akrizhevsky/cuda-convnet2/blob/master/layers/
layers-imagenet-1gpu.cfg
Note: All the fully_connected layers have been transformed to conv2d layers.
To use in classification mode resize input to 224x224. To use in fully
convolutional mode set spatial_squeeze to false.
The LRN layers have been removed and change the initializers from
random_normal_initializer to xavier_initializer.
Args:
inputs: a tensor of size [batch_size height width channels].
num_classes: number of predicted classes.
is_training: whether or not the model is being trained.
dropout_keep_prob: the pr
