He discusses the design processidentifying a problem and exploring the inputs and data sets that could be leveraged to address the problem. Neuronal firing rate ranges from 1 to hertz and there are on average 7000 synapses in a human neuron so the total number of action potentials being transmitted in your brain per second is of the. As the thickeness of the lines change, you can see the neural network learning. Finally, well apply this knowledge by designing a neural network based off what weve explored in this course, putting pen to paper and challenging you to design your own.
