Russian scientists from ITMO University have discovered that crystals similar to the mineral tenorite, when irradiated with a laser, mimic the operation of human brain synapses. This opens up prospects for their use as building blocks for artificial neural networks.
Researchers have successfully tested artificial synapses created on the basis of crystals. These crystals served as the basis for training a neural network, which was learning to recognize handwritten digits in images. In just three training stages, artificial intelligence achieved an impressive accuracy of 95%, which is one of the best results for modern neuromorphic materials.
The human brain works differently than computers: neurons simultaneously store and process information, perceive analog signals, and are able to flexibly change sensitivity. This complicates the creation of AI and requires significant computing resources. To solve the problem, scientists are developing artificial analogs of neurons and synapses that mimic natural neural networks.
