Scientists develop laser-based artificial neuron for rapid data processing

Scientists have created a new laser-based artificial neuron that mimics human brain cells. This neuron processes data much faster than existing artificial neurons, transmitting information up to 100,000 times quicker than traditional spiking neurons. The new system uses graded signals, allowing it to avoid the reset period that limits speed in spiking neurons. In tests, it processed 700 heartbeat samples for arrhythmia at 100 million heartbeats per second, achieving over 98% accuracy. Additionally, the system classified handwritten numbers at nearly 35 million digits per second with 92% accuracy. Researchers believe connecting multiple graded neurons could enhance computing power further.
