Abstract: A graph includes nodes connected with one or more edges. Each node in the graph may be encoded in a neuron in a neural network. The neural network may include neurons arranged in a spiking neuromorphic architecture. To find the shortest path between a first node and a second node in the graph, a spike may propagate from a first neuron encoding the first node to a second neuron encoding the second node. Another spike may propagate from the second neuron to the first neuron. Each neuron spiking in a propagation may store a value that indicates the depth of the neuron in a propagation path. A spiking neuron may generate two values in the two propagations, respectively. A spiking neuron having two equal values may be identified. The shortest path includes one or more edges that connect the nodes encoded in the identified spiking neurons.

Abstract: A neural network, which can solve conic optimization problems may include a first layer, a second layer, and a third layer. The first layer includes first neurons encoding constraint coefficients of the conic optimization problem. The second layer includes second neurons encoding decision variables of the conic optimization problem. The third layer includes an integrator neuron. Data may be sent from a first neuron to a second neuron or from the second neuron to the first neuron. A neuron, after receiving data from another neuron, may update its internal state parameter based on the data and the weight of the connection between the two neurons. The communication may be triggered by the internal state parameter of the neuron sending the data meets a criterion. After the internal state parameter of the integrator neuron meets a criterion, the integrator neuron may output a solution to the conic optimization problem.

Abstract: Various systems and methods for implementing unsupervised or reinforcement learning operations for a neuron weight used in a neural network are described. In an example, the learning operations include processing a spike train input at a neuron of a spiking neural network, applying a synaptic weight, and observing spike events occurring before and after the neuron processing based on respective spike traces. A synaptic weight update process operates to generate a new value of the synaptic weight based upon the spike traces, configuration values, and a reference weight value. A reference weight update process also operates to generate a new value of the reference value for significant changes to the synaptic weight. Reinforcement may be provided in some examples to implement changes to the reference weight in reduced time. In some examples, the techniques may be implemented in a neuromorphic hardware implementation of the spiking neural network.

Abstract: Techniques and mechanisms to update a synaptic weight of a spiking neural network which is trained to provide a decision of a decision-making sequence. In an embodiment, a synapse of the spiking neural network is associated with a weight which is to be given to communications via that given synapse. The spiking neural network generates output signaling, indicating a decision to the decision-making process, which is evaluated to determine whether, according to predefined test criteria, the decision-making process is successful or unsuccessful. One or more nodes of the spiking neural network receive a reward/penalty signal which is based on the evaluation. In response to the reward/penalty signal indicating a reward event or a penalty event, a synaptic weight value is updated. In another embodiment, input signaling provided to the spiking neural network represents a sub-sequence of two or more most recent states in a sequence of states.
