Does the routing associated with the connections between layers. It may be directly used as a layer/node, routing all the data at once. If the routing/mapping is not injective the processed data may be quite large and probably contains many redundant copies of the input data. So is this case one may instead use nodes for individual output channels and put each in a MultiNode. SwitchboardLayer is the most general version of a switchboard layer, since there is no imposed rule for the connection topology. For practical applications should often derive more specialized classes.

Create a generic switchboard. The input and output dimension as well as dtype have to be fixed at initialization time. Keyword arguments: input_dim -- Dimension of the input data (number of connections). connections -- 1d Array or sequence with an entry for each output connection, containing the corresponding index of the input connection.

Return True if the node can be inverted, False otherwise.

Return True if the node can be trained, False otherwise.
