g'(x) is the derivative of g(x)

If g(x) is choosen to be the sigmoid, then g'(x) would be:

g'(x)=g(x)*(1-g(x))

excellent work!

[Miles Smith]

the bias value plus the sum of all the neuron's inputs multiplied by their weights

[Tùng Trịnh]

so what is the "in" inside the g'()?

[Jonathan Stiansen]

America does do this. Go to coursera, udacity, edx.org. All of these have artificial intelligence courses I believe.

Ahhhhhhrgh his x for multiplication freaked me out :) But nice lecture!

[tj1990]

why does the USA not do this(money probably((of course))? MIT has Open Course Ware, but its not as well documented....can we get these videos with subtitles? the accents are rather thick..
