How does a single neuron, utilizing a non-linear activation, function conceptually within the network's approximation process?
Answer
It operates like a soft switch or a localized 'probe' in the input space.
A neuron with a non-linear activation acts locally, serving as a 'probe' or 'switch' that contributes one small, localized segment to the overall piecewise approximation built by the network.
