Introduction to Financial Prediction using Artificial Intelligent Method
... The dendrites are extensions of a neuron which connect to other neurons to form a neural network, while synapses are a gateway which connects to dendrites that come from other neurons. A biological neuron may thus be connected to other neurons as well as accepting connections from other neurons, and ...
