Deep Learning and Its Evolution
Deep learning evolved from artificial neural networks , which have existed since the 1940s. Neural networks are interconnected networks of processing units called artificial neurons that loosely mimic the axons found in a biological brain. In a biological neuron, dendrites receive input signals from various neighboring neurons, typically more than one thousand of them. These modified signals are then passed on to the cell body or soma of the neuron, where these signals are summed together ...
