The idea of ANNs is based on the belief that working of human brain by making the right connections, can be imitated using silicon and wires as living neurons and dendrites. The neural network model input included aw, temperature, and time, whilst the fungal population level was the model output. The very first artificial neural network was created by Minsky as a graduate student in 1951 (see “Learning Machine, 1951”), but the approach was limited at first, and even Minsky himself soon turned his focus to other approaches for creating intelligent machines. Artificial neural networks are computers whose architecture is modeled after the brain. These inputs create electric impulses, which quickly t… Neurons are its fundamental units of computation.
