An artificial neural circuit was able to recognise the images of three letters of the alphabet. This elementary artificial brain capable of succeeding in this typical human task was designed by an international team of researchers from the University of California Santa Barbara (USA).
Created by engineer Dmitri B. Strukov and his colleague, the elementary neural circuit has 100 artificial synapses, a very simple structure compared to the human brain which has 1015 synaptic connections. To note that the neuronal synapses are areas for transmitting electrical or chemical signals between neurones, or between other cells.
The neural circuit thus created was able to recognise three letters of the alphabet ( “z”, “v” and “n”) through their images, stylized differently.
To create this artificial system capable of accomplishing this task as a typical human, the researchers used a technology based on memristor (for ‘memory’ and ‘resistor’). The latter is an electrical device which resistance changes according to the flow of electric charge.
