theanets.layers.base.Product¶
-
class
theanets.layers.base.
Product
(name=None, **kwargs)[source]¶ Multiply several inputs together elementwise.
Notes
This layer performs an elementwise multiplication of multiple inputs; all inputs must be the same shape.
Outputs
out
— elementwise product of its inputs
-
__init__
(name=None, **kwargs)¶ x.__init__(…) initializes x; see help(type(x)) for signature

()Create a specification dictionary for this layer. transform
(inputs)Transform the inputs for this layer into an output for the layer. Attributes
input_name
Name of layer input (for layers with one input). input_shape
Shape of layer input (for layers with one input). input_size
Size of layer input (for layers with one input). output_name
Full name of the default output for this layer. output_shape
Shape of default output from this layer. output_size
Number of “neurons” in this layer’s default output. params
A list of all parameters in this layer. -
transform
(inputs)[source]¶ Transform the inputs for this layer into an output for the layer.
Parameters: - inputs : dict of Theano expressions
Symbolic inputs to this layer, given as a dictionary mapping string names to Theano expressions. See
Layer.connect()
.
Returns: - output : Theano expression
The output for this layer is the same as the input.
- updates : list
An empty updates list.
