tf.compat.v1.layers.Conv3D(
filters, kernel_size, strides=(1, 1, 1), padding='valid',
data_format='channels_last', dilation_rate=(1, 1, 1), activation=None,
use_bias=True, kernel_initializer=None, bias_initializer=tf.zeros_initializer(),
kernel_regularizer=None, bias_regularizer=None, activity_regularizer=None,

)
This layer creates a convolution kernel that is convolved
(actually cross-correlated) with the layer input to produce a tensor of
outputs. If use_bias
is True (and a bias_initializer
is provided),
a bias vector is created and added to the outputs. Finally, if
activation
is not None
, it is applied to the outputs as well.
Arguments | |
---|---|
filters
|
Integer, the dimensionality of the output space (i.e. the number of filters in the convolution). |
kernel_size
|
An integer or tuple/list of 3 integers, specifying the depth, height and width of the 3D convolution window. Can be a single integer to specify the same value for all spatial dimensions. |
strides
|
An integer or tuple/list of 3 integers,
specifying the strides of the convolution along the depth,
height and width.
Can be a single integer to specify the same value for
all spatial dimensions.
Specifying any stride value != 1 is incompatible with specifying
any dilation_rate value != 1.
|
padding
|
One of "valid" or "same" (case-insensitive).
"valid" means no padding. "same" results in padding evenly to
the left/right or up/down of the input such that output has the same
height/width dimension as the input.
|
data_format
|
A string, one of channels_last (default) or channels_first .
The ordering of the dimensions in the inputs.
channels_last corresponds to inputs with shape
(batch, depth, height, width, channels) while channels_first
corresponds to inputs with shape
(batch, channels, depth, height, width) .
|
dilation_rate
|
An integer or tuple/list of 3 integers, specifying
the dilation rate to use for dilated convolution.
Can be a single integer to specify the same value for
all spatial dimensions.
Currently, specifying any dilation_rate value != 1 is
incompatible with specifying any stride value != 1.
|
activation
|
Activation function. Set it to None to maintain a linear activation. |
use_bias
|
Boolean, whether the layer uses a bias. |
kernel_initializer
|
An initializer for the convolution kernel. |
bias_initializer
|
An initializer for the bias vector. If None, the default initializer will be used. |
kernel_regularizer
|
Optional regularizer for the convolution kernel. |
bias_regularizer
|
Optional regularizer for the bias vector. |
activity_regularizer
|
Optional regularizer function for the output. |
kernel_constraint
|
Optional projection function to be applied to the
kernel after being updated by an Optimizer (e.g. used to implement
norm constraints or value constraints for layer weights). The function
must take as input the unprojected variable and must return the
projected variable (which must have the same shape). Constraints are
not safe to use when doing asynchronous distributed training.
|
bias_constraint
|
Optional projection function to be applied to the
bias after being updated by an Optimizer .
|
trainable
|
Boolean, if True also add variables to the graph collection
GraphKeys.TRAINABLE_VARIABLES (see tf.Variable ).
|
name
|
A string, the name of the layer. |
