The present disclosure relates to a method a system and an aggregation engine for providing a structural representation of a physical entity. Processing units provide representation of elements composing the physical entity. Processing units comprise a label, which represent the elements, and a state. Links are established between the processing units. By iteration in the aggregation engine, the states and labels of the processing units are updated based on states and labels of linked processing units. A graphical representation of the physical entity is obtained based on the labels, on the states, and on the links.

Method, system and aggregation engine for providing structural representations of physical entities

A spiking neural network has a layer of connected neurons exchanging signals. Each neuron is connected to at least one other neuron. A neuron is active if it spikes at least once during a time interval. Time-varying synaptic weights are computed between each neuron and at least one other neuron connected thereto. These weights are computed according to a number of active neurons that are connected to the neuron. The weights are also computed according to an activity of the spiking neural network during the time interval. Spiking of each neuron is synchronized according to a number of active neurons connected to the neuron and according to the weights. A pattern is submitted to the spiking neural network for generating sequences of spikes, which are modulated over time by the spiking synchronization. The pattern is characterized according to the sequences of spikes generated in the spiking neural network.
