Artificial neurons

Now, let's get into the guts of a neural network. What is a neuron? And how do we make a network out of them?

An artificial neuron is a software construction that approximates the workings of the neurons in your brain. If you can remember what you learned in biology, a biological or natural neuron has inputs, or dendrites, that connect it to other neurons or to sensor inputs. All of the inputs come to a central body, and then leave via the axion, or connection, to other neurons via other dendrites. The connection between neurons is called a synapse, which is a tiny gap that the signal from the nerve has to jump. A neuron takes inputs, processes them, and activates, or sends an output, after some level or threshold is reached: ...
