1D convolution layer (e.g. temporal convolution).
This layer creates a convolution kernel that is convolved with the layer
input over a single spatial (or temporal) dimension to produce a tensor of
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 an
input_shape argument (list of integers or
NULL , e.g.
(10, 128) for
sequences of 10 vectors of 128-dimensional vectors, or
(NULL, 128) for
variable-length sequences of 128-dimensional vectors.

Integer, the dimensionality of the output space (i.e. the number of output filters in the convolution).
An integer or list of a single integer, specifying the length of the 1D convolution window.
An integer or list of a single integer, specifying the stride
length of the convolution. Specifying any stride value != 1 is incompatible
with specifying any
A string, one of
an integer or list of a single integer, specifying the
dilation rate to use for dilated convolution. Currently, specifying any
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 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,

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.
