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 NULL, it 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(128L, 128L, 128L, 3L) for 128x128x128 volumes with a single channel, in data_format="channels_last".

layer_conv_3d(object, filters, kernel_size, strides = c(1L, 1L, 1L),
padding = "valid", data_format = NULL, dilation_rate = c(1L, 1L,
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)

## Arguments

object Model or layer object Integer, the dimensionality of the output space (i.e. the number of output filters in the convolution). An integer or 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. An integer or list of 3 integers, specifying the strides of the convolution along each spatial dimension. 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. one of "valid" or "same" (case-insensitive). 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, spatial_dim1, spatial_dim2, spatial_dim3, channels) while channels_first corresponds to inputs with shape (batch, channels, spatial_dim1, spatial_dim2, spatial_dim3). It defaults to the image_data_format value found in your Keras config file at ~/.keras/keras.json. If you never set it, then it will be "channels_last". an integer or 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 function to use. If you don't specify anything, no activation is applied (ie. "linear" activation: a(x) = x). Boolean, whether the layer uses a bias vector. Initializer for the kernel weights matrix. Initializer for the bias vector. Regularizer function applied to the kernel weights matrix. 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, batch_input_shape=c(10, 32) indicates that the expected input will be batches of 10 32-dimensional vectors. batch_input_shape=list(NULL, 32) indicates batches of an arbitrary number of 32-dimensional vectors. Fixed batch size for layer The data type expected by the input, as a string (float32, float64, int32...) 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.

## Input shape

5D tensor with shape: (samples, channels, conv_dim1, conv_dim2, conv_dim3) if data_format='channels_first' or 5D tensor with shape: (samples, conv_dim1, conv_dim2, conv_dim3, channels) if data_format='channels_last'.

## Output shape

5D tensor with shape: (samples, filters, new_conv_dim1, new_conv_dim2, new_conv_dim3) if data_format='channels_first' or 5D tensor with shape: (samples, new_conv_dim1, new_conv_dim2, new_conv_dim3, filters) if data_format='channels_last'. new_conv_dim1, new_conv_dim2 and new_conv_dim3 values might have changed due to padding.
