Apparatus and methods for rate-modulated plasticity in a neuron network

A non-transitory computer-readable medium having program code recorded thereon, the program code comprising:

• program code to update a connection configured to provide a stimulus to an artificial neuron, the update configured to:
• when the stimulus precedes a response generated by the neuron, potentiate the connection;
• when the response precedes the stimulus:
• potentiate the connection when a neuron activity is below a threshold level;
• and
• depress the connection when the neuron activity is above the threshold level.

A method of managing a connection in a neuron network based on at least one signal from a neuron, the method comprising:

• receiving at least one input via the connection;
• sending the at least one signal at a time proximate to the received at least one input;
• when the at least one signal is sent prior to the receiving of the at least one input, demoting the connection;
• and
• when the at least one signal is sent after the receiving of the input, promoting the connection.

A sensory processing neuron network apparatus, comprising:

• a neuron;
• and
• a connection configured to provide an input to the neuron configured to generate a response based on the input;
• wherein the connection is further configured to be:
• potentiated when the input is within an interval from the response;
• adjusted when the input occurs subsequent to the response, the adjustment being
• determined based on activity of the neuron prior to the response,
• wherein a neuron activity is determined based on at least a number of neuron responses within a time interval to precede a second input, the number of responses including the response.

An apparatus for managing a connection in a neuron network based on at least one signal from a neuron, the apparatus comprising:

• a memory;
• and
• at least one processor coupled to the memory, the at least one processor configured:
• to receive at least one input via the connection;
• to send the at least one signal at a time proximate to the received at least one input;
• to demote the connection when the at least one signal is sent prior to the receiving of the at least one input;
• and
• to promote the connection when the at least one signal is sent after the receiving of the input.

An apparatus for managing a connection in a neuron network based on at least one signal from a neuron, the apparatus comprising:

• means for receiving at least one input via the connection;
• means for sending the at least one signal at a time proximate to the received at least one input;
• means for demoting the connection when the at least one signal is sent prior to the receiving of the at least one input;
• and
• means for promoting the connection when the at least one signal is sent after the receiving of the input.
