"Giant intuitive diagram showing how an artificial neural network works; by allowing error signals (aka changes in costs) to “trickle” backwards from the output layer.

For example: “Trickling” backwards simply means a value (aka cost) computed at some neuron \(j\) in layer \(L\) is input to values generated by computations of some prior neuron \(k\) in layer \(L-1\). Some cost computed from neuron \(k\) then becomes input to values generated by computations of some prior neuron \(m\), in layer \(L-2\)."
