class Dense(Layer):
 """Just your regular densely-connected NN layer.
 `Dense` implements the operation:
 `output = activation(dot(input, kernel) + bias)`
 where `activation` is the element-wise activation function
 passed as the `activation` argument, `kernel` is a weights matrix
 created by the layer, and `bias` is a bias vector created by the layer
 (only applicable if `use_bias` is `True`).
 Note: if the input to the layer has a rank greater than 2, then
 it is flattened prior to the initial dot product with `kernel`.
 # Example
 ```python
  # as first layer in a sequential model:
  model = Sequential()
  model.add(Dense(32, input_shape=(16,)))
  # now the model will take as input arrays of shape (*, 16)
  # and output arrays of shape (*, 32)
  # after the first layer, you don't need to specify
  # the size of the input anymore:
  model.add(Dense(32))
 ```
 # Arguments
  units: Positive integer, dimensionality of the output space.
  activation: Activation function to use
   (see [activations](../activations.md)).
   If you don't specify anything, no activation is applied
   (ie. "linear" activation: `a(x) = x`).
  use_bias: Boolean, whether the layer uses a bias vector.
  kernel_initializer: Initializer for the `kernel` weights matrix
   (see [initializers](../initializers.md)).
  bias_initializer: Initializer for the bias vector
   (see [initializers](../initializers.md)).
  kernel_regularizer: Regularizer function applied to
   the `kernel` weights matrix
   (see [regularizer](../regularizers.md)).
  bias_regularizer: Regularizer function applied to the bias vector
   (see [regularizer](../regularizers.md)).
  activity_regularizer: Regularizer function applied to
   the output of the layer (its "activation").
   (see [regularizer](../regularizers.md)).
  kernel_constraint: Constraint function applied to
   the `kernel` weights matrix
   (see [constraints](../constraints.md)).
  bias_constraint: Constraint function applied to the bias vector
   (see [constraints](../constraints.md)).
 # Input shape
  nD tensor with shape: `(batch_size, ..., input_dim)`.
  The most common situation would be
  a 2D input with shape `(batch_size, input_dim)`.
 # Output shape
  nD tensor with shape: `(batch_size, ..., units)`.
  For instance, for a 2D input with shape `(batch_size, input_dim)`,
  the output would have shape `(batch_size, units)`.
