Patent number: 9208432Abstract: Apparatus and methods for learning and training in neural network-based devices. In one implementation, the devices each comprise multiple spiking neurons, configured to process sensory input. In one approach, alternate heterosynaptic plasticity mechanisms are used to enhance learning and field diversity within the devices. The selection of alternate plasticity rules is based on recent post-synaptic activity of neighboring neurons. Apparatus and methods for simplifying training of the devices are also disclosed, including a computer-based application. A data representation of the neural network may be imaged and transferred to another computational environment, effectively copying the brain. Techniques and architectures for achieve this training, storing, and distributing these data representations are also disclosed.Type: GrantFiled: March 14, 2013Date of Patent: December 8, 2015Assignee: Brain CorporationInventors: Marius Buibas, Eugene M.

Publication number: 20150347796Abstract: The present invention relates to a polychronous wave propagation system that is based on relative timing between two or more propagated waves through a wave propagation medium. The relative timing may be associated with interference patterns of energy between the propagated waves. Operational behavior of the polychronous wave propagation system is based on the relative timing of the propagated waves and distances between initiators that transmit the propagated waves and responders that receive the propagated waves. The operational behavior may include arithmetical computations, memory storage, Boolean functions, frequency-based computations, or the like. The polychronous wave propagation system relies on time delays between the propagated waves that result from propagation velocities of the propagated waves through the wave propagation medium. By incorporating the time delays into the system, operational capacity may be greatly enhanced.Type: ApplicationFiled: August 14, 2015Publication date: December 3, 2015Inventors: Frank C.

Patent number: 9165245Abstract: Apparatus and methods for partial evaluation of synaptic updates in neural networks. In one embodiment, a pre-synaptic unit is connected to a several post synaptic units via communication channels. Information related to a plurality of post-synaptic pulses generated by the post-synaptic units is stored by the network in response to a system event. Synaptic channel updates are performed by the network using the time intervals between a pre-synaptic pulse, which is being generated prior to the system event, and at least a portion of the plurality of the post synaptic pulses. The system event enables removal of the information related to the portion of the post-synaptic pulses from the storage device. A shared memory block within the storage device is used to store data related to post-synaptic pulses generated by different post-synaptic nodes. This configuration enables memory use optimization of post-synaptic units with different firing rates.Type: GrantFiled: May 12, 2014Date of Patent: October 20, 2015Assignee: QUALCOMM TECHNOLOGIES INC.Inventors: Eugene M.

Patent number: 9147156Abstract: Apparatus and methods for efficient synaptic update in a network such as a spiking neural network. In one embodiment, the post-synaptic updates, in response to generation of a post-synaptic pulse by a post-synaptic unit, are delayed until a subsequent pre-synaptic pulse is received by the unit. Pre-synaptic updates are performed first following by the post-synaptic update, thus ensuring synaptic connection status is up-to-date. The delay update mechanism is used in conjunction with system “flush” events in order to ensure accurate network operation, and prevent loss of information under a variety of pre-synaptic and post-synaptic unit firing rates. A large network partition mechanism is used in one variant with network processing apparatus in order to enable processing of network signals in a limited functionality embedded hardware environment.Type: GrantFiled: September 21, 2011Date of Patent: September 29, 2015Assignee: QUALCOMM TECHNOLOGIES INC.Inventors: Eugene M.

Patent number: 9122994Abstract: Object recognition apparatus and methods useful for extracting information from an input signal. In one embodiment, the input signal is representative of an element of an image, and the extracted information is encoded into patterns of pulses. The patterns of pulses are directed via transmission channels to a plurality of detector nodes configured to generate an output pulse upon detecting an object of interest. Upon detecting a particular object, a given detector node elevates its sensitivity to that particular object when processing subsequent inputs. In one implementation, one or more of the detector nodes are also configured to prevent adjacent detector nodes from generating detection signals in response to the same object representation. The object recognition apparatus modulates properties of the transmission channels by promoting contributions from channels carrying information used in object recognition.Type: GrantFiled: June 2, 2011Date of Patent: September 1, 2015Assignee: Brain CorporationInventors: Filip Lukasz Piekniewski, Csaba Petre, Sach Hansen Sokol, Botond Szatmary, Jayram Moorkanikara Nageswaran, Eugene M.

Patent number: 9117176Abstract: Apparatus and methods for high-level neuromorphic network description (HLND) framework that may be configured to enable users to define neuromorphic network architectures using a unified and unambiguous representation that is both human-readable and machine-interpretable. The framework may be used to define nodes types, node-to-node connection types, instantiate node instances for different node types, and to generate instances of connection types between these nodes.

Patent number: 9014416Abstract: Artificial retina may be implemented. A retinal apparatus may comprise an input pixel layer, hidden photoreceptive layer, an output neuron layer, and/or other components. Individual cones of the photoreceptive layer may be configured to receive input stimulus from one or more cones within the cone circle of confusion.

Patent number: 8983216Abstract: Systems and methods for processing image signals are described. One method comprises obtaining a generator signal based on an image signal and determining relative latencies associated with two or more pulses in a pulsed signal using a function of the generator signal that can comprise a logarithmic function.

Patent number: 8849735Abstract: In Pavlovian and instrumental conditioning, rewards typically come seconds after reward-triggering actions, creating an explanatory conundrum known as the distal reward problem or the credit assignment problem. How does the brain know what firing patterns of what neurons are responsible for the reward if (1) the firing patterns are no longer there when the reward arrives and (2) most neurons and synapses are active during the waiting period to the reward? A model network and computer simulation of cortical spiking neurons with spike-timing-dependent plasticity (STDP) modulated by dopamine (DA) is disclosed to answer this question. STDP is triggered by nearly-coincident firing patterns of a presynaptic neuron and a postsynaptic neuron on a millisecond time scale, with slow kinetics of subsequent synaptic plasticity being sensitive to changes in the extracellular dopamine DA concentration during the critical period of a few seconds after the nearly-coincident firing patterns.Type: GrantFiled: January 23, 2012Date of Patent: September 30, 2014Assignee: Neurosciences Research Foundation, Inc.Inventor: Eugene M.
