This layer creates a convolution kernel that is convolved with the layer
input to produce a tensor of outputs. If
use_bias is TRUE, a bias vector is
created and added to the outputs. Finally, if
activation is not
is applied to the outputs as well. When using this layer as the first layer
in a model, provide the keyword argument
input_shape (list of integers,
does not include the sample axis), e.g.
input_shape=c(128, 128, 3) for
128x128 RGB pictures in
layer_conv_2d( object, filters, kernel_size, strides = c(1L, 1L), padding = "valid", data_format = NULL, dilation_rate = c(1L, 1L), groups = 1L, activation = NULL, use_bias = TRUE, kernel_initializer = "glorot_uniform", bias_initializer = "zeros", kernel_regularizer = NULL, bias_regularizer = NULL, activity_regularizer = NULL, kernel_constraint = NULL, bias_constraint = NULL, input_shape = NULL, batch_input_shape = NULL, batch_size = NULL, dtype = NULL, name = NULL, trainable = NULL, weights = NULL )
What to call the new
Integer, the dimensionality of the output space (i.e. the number of output filters in the convolution).
An integer or list of 2 integers, specifying the width and height of the 2D convolution window. Can be a single integer to specify the same value for all spatial dimensions.
An integer or list of 2 integers, specifying the strides of
the convolution along the width and height. Can be a single integer to
specify the same value for all spatial dimensions. Specifying any stride
value != 1 is incompatible with specifying any
A string, one of
an integer or list of 2 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
A positive integer specifying the number of groups in which the
input is split along the channel axis. Each group is convolved separately
Activation function to use. If you don't specify anything,
no activation is applied (ie. "linear" activation:
Boolean, whether the layer uses a bias vector.
Initializer for the
Initializer for the bias vector.
Regularizer function applied to the
Regularizer function applied to the bias vector.
Regularizer function applied to the output of the layer (its "activation")..
Constraint function applied to the kernel matrix.
Constraint function applied to the bias vector.
Dimensionality of the input (integer) not including the samples axis. This argument is required when using this layer as the first layer in a model.
Shapes, including the batch size. For instance,
Fixed batch size for layer
The data type expected by the input, as a string (
An optional name string for the layer. Should be unique in a model (do not reuse the same name twice). It will be autogenerated if it isn't provided.
Whether the layer weights will be updated during training.
Initial weights for layer.
4D tensor with shape:
(samples, channels, rows, cols)
if data_format='channels_first' or 4D tensor with shape:
(samples, rows, cols, channels) if data_format='channels_last'.
4D tensor with shape:
(samples, filters, new_rows, new_cols) if data_format='channels_first' or 4D tensor with shape:
(samples, new_rows, new_cols, filters) if data_format='channels_last'.
cols values might have changed due to padding.
