Original Motivation - Software that mimics the Human brain, how it learns and think.
<aside> 💡 So as you go deeper into neural networks and into deep learning, even though the origins were biologically motivated, don't take the biological motivation too seriously. In fact, those of us that do research in deep learning have shifted away from looking to biological motivation that much. But instead, they're just using engineering principles to figure out how to build algorithms that are more effective., marked from 0 hours 6 minutes 57 seconds until 0 hours 7 minutes 21 secondsSo as you go deeper into neural networks and into deep learning, even though the origins were biologically motivated, don't take the biological motivation too seriously.

I'm going to switch the terminology a little bit and use the alphabet a to denote the output of this logistic regression algorithm. The term a stands for activation.
Activation → it's actually a term from neuroscience, and it refers to how much a neuron is sending a high output to other neurons downstream from it.
A logistic regression algorithm is much simpler than what any biological neuron in your brain or mine does. Which is why the artificial neural network is such a vastly oversimplified model of the human brain.
