reservoirpy.ops.link_feedback

class reservoirpy.ops.link_feedback(

sender: Node | Model | Sequence[Node | Model],

receiver: Node | Model | Sequence[Node | Model],

)

Create a feedback connection from the sender to the receiver. Feedback connections are regular node-to-node connections with a delay of one timestep.

If sender or receiver is a Model or a list of Nodes or Models, all outputs of sender will be connected as feedback to receiver.

You can also perform this operation using the << operator:

node1 = node1 << node2
# with feedback from a Model
node1 = node1 << (fbnode1 >> fbnode2)
# with feedback from a list of nodes or models
node1 = node1 << [fbnode1, fbnode2, ...]

You can also use this function to define feedback:

node1 = link_feedback(node1, node2)

Parameters:

• sender (Node, Model, or list of Nodes or Models) – Node(s) or Model(s) sending feedback.

• receiver (Node, Model, or list of Nodes or Models) – Node(s) or Model(s) receiving feedback.

Returns:

A model instance with all node and connections from sender and receiver and with feedback connections from sender to receiver.

Return type:

Model

Raises:

TypeError – If any of the senders or receivers are not Nodes or Models.
