optional shape list, only to be specified if include_top
is FALSE (otherwise the input shape has to be (224, 224, 3)
(with
channels_last
data format) or (3, 224, 224) (with channels_first
data
format). It should have exactly 3 inputs channels, and width and height
should be no smaller than 32. E.g. (200, 200, 3)
would be one valid
value.
controls the width of the network.
If alpha
< 1.0, proportionally decreases the number of filters in each layer.
If alpha
> 1.0, proportionally increases the number of filters in each layer.
If alpha
= 1, default number of filters from the paper are used at each layer.
depth multiplier for depthwise convolution (also called the resolution multiplier)
dropout rate
whether to include the fully-connected layer at the top of the network.
NULL
(random initialization) or imagenet
(ImageNet
weights)
optional Keras tensor (i.e. output of layers.Input()
)
to use as image input for the model.
Optional pooling mode for feature extraction when
include_top
is FALSE
.
- NULL
means that the output of the model will be the 4D tensor output
of the last convolutional layer.
- avg
means that global average pooling will be applied to the output
of the last convolutional layer, and thus the output of the model will
be a 2D tensor.
- max
means that global max pooling will be applied.
optional number of classes to classify images into, only to be
specified if include_top
is TRUE, and if no weights
argument is
specified.
input tensor, 4D
Tensor encoding a batch of predictions.
integer, how many top-guesses to return.
File path
application_mobilenet()
and mobilenet_load_model_hdf5()
return a
Keras model instance. mobilenet_preprocess_input()
returns image input
suitable for feeding into a mobilenet model. mobilenet_decode_predictions()
returns a list of data frames with variables class_name
, class_description
,
and score
(one data frame per sample in batch input).
The mobilenet_preprocess_input()
function should be used for image
preprocessing. To load a saved instance of a MobileNet model use
the mobilenet_load_model_hdf5()
function. To prepare image input
for MobileNet use mobilenet_preprocess_input()
. To decode
predictions use mobilenet_decode_predictions()
.
MobileNet is currently only supported with the TensorFlow backend.
