System and method for a recursive cortical network
A system includes: a recursively architected network of sub-networks organized into a hierarchical layers; the sub-networks including at least a parent feature node, a pool node, a parent-specific child feature (PSCF) node, and a child feature node; the parent feature node of at least one sub-network configured with a selection function actionable on at least two pool nodes connected to the parent feature node of the at least one sub-network; the pool node of the at least one sub-network configured with a selection function actionable on at least two PSCF nodes connected to the pool node of the at least one sub-network; the PSCF node of the at least one sub-network configured to activate a connected child feature node; the child feature node connectable to at least a parent feature node of a sub-network at a lower hierarchical layer.
1. A method for generating patterns with a network comprising:
providing a recursive network of sub-networks with a parent feature input node and at least two child feature output nodes;
propagating node selection down the network layer hierarchy in a manner consistent with node connections of sub-networks of the network, the propagation within the sub-network comprising:
at an activated parent feature node of a sub-network, selecting a pool node consistent with a selection function of the parent feature node;
at a pool node of a sub-network, selecting at least a first parent-specific child feature (PSCF) node that corresponds to a child feature node of the sub-network; and
in response to the selection of a first node of the sub-network, enforcing a selection constraint on at least a second node of a second pool according to a lateral constraint node of the sub-network; and
compiling the state of final child feature nodes of the network into a generated output.
2. The method of claim 1 , wherein the first node is the first PSCF node, and the second node of the second pool is a PSCF node.
3. The method of claim 2 , wherein the second PSCF node of the second pool is within the same sub-network.
4. The method of claim 2 , wherein the second PSCF node of the second pool is in a second sub-network.
5. The method of claim 2 , wherein first PSCF node is in a network of a first time instant and the second PSCF node of the second pool is in a network of a second time instant.
6. The method of claim 2 , further comprising in response to selecting the PSCF node selecting at least one child feature node; mapping selected child feature nodes to data features that are compiled into the generated output.
7. The method of claim 6 , wherein the generated output is an image.
8. The method of claim 6 , wherein the generated output is a sequence of images.
9. The method of claim 6 , wherein the generated output is audio.
10. The method of claim 6 , wherein the selection functions are Boolean logical selection functions.
11. The method of claim 10 , wherein the child feature nodes of a first layer sub-network are the parent feature nodes for at least two sub-networks in a second layer.
12. The method of claim 11 , wherein selecting the pool node consistent with a selection function comprises selecting each pool node connected to the parent node according to a logical AND selection function; wherein selecting the first PSCF node comprises randomly selecting only one PSCF node from the set of PSCF nodes connected to the pool node according to a logical XOR selection function of the pool node.
