layer_locally_connected_2d works similarly to
that weights are unshared, that is, a different set of filters is applied at
each different patch of the input.
layer_locally_connected_2d( object, filters, kernel_size, strides = c(1L, 1L), padding = "valid", data_format = NULL, 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, implementation = 1L, batch_size = NULL, name = NULL, trainable = NULL, weights = NULL )
Model or layer object
Integer, the dimensionality of the output space (i.e. the number output of 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

either 1, 2, or 3. 1 loops over input spatial locations
to perform the forward pass. It is memory-efficient but performs a lot of
(small) ops. 2 stores layer weights in a dense but sparsely-populated 2D
matrix and implements the forward pass as a single matrix-multiply. It uses
a lot of RAM but performs few (large) ops. 3 stores layer weights in a
sparse tensor and implements the forward pass as a single sparse
matrix-multiply. How to choose: 1: large, dense models, 2: small models, 3:
large, sparse models, where "large" stands for large input/output
activations (i.e. many

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.
