Class SameInputLayer


SameInputLayer is a layer were all nodes receive the full input.

So instead of splitting the input according to node dimensions, all nodes
receive the complete input data.

Instance Methods [hide private]
 
__init__(self, nodes, dtype=None)

execute(self, x, *args, **kwargs)
Process the data through the internal nodes.
 
train(self, x, *args, **kwargs)

Method Details [hide private]

__init__(self, nodes, dtype=None)
(Constructor)

 
Setup the layer with the given list of nodes.

The input dimensions for the nodes must all be equal, the output
dimensions can differ (but must be set as well for simplicity reasons).

Keyword arguments:
nodes -- List of the nodes to be used.

Overrides: object.__init__

_execute(self, x, *args, **kwargs)

 
Process the data through the internal nodes.

Overrides: Node._execute

_pre_execution_checks(self, x)

 
Make sure that output_dim is set and then perform nromal checks.

Overrides: Node._pre_execution_checks

_train(self, x, *args, **kwargs)

 
Perform single training step by training the internal nodes.

Overrides: Node._train

execute(self, x, *args, **kwargs)

 
Process the data through the internal nodes.

Overrides: Node.execute

is_invertible()
Static Method

 
Return True if the node can be inverted, False otherwise.
Overrides: Node.is_invertible
(inherited documentation)

train(self, x, *args, **kwargs)

 
Perform single training step by training the internal nodes.

Overrides: Node.train
