Neural Nets: Back propagation intuition

As I was preparing for a discussion with a group of friends on back propagation, I came across this video by professor Patrick Winston and I could not be happier. In only about 40 min, Prof Winston gives the most impressive intuition ever about what backpropagation is. Prof Winston starts from the definition of the problem and then follows through with the representation of the inputs. he uses a not normal

Discrete Probability Distributions

8 Discrete Probability Distributions¶ 8.2 Binomial Distribution¶ The following code plots the probability mass function (PMF) of $B_{p,n}$, the binomial distribution with parameters $p$ and $n$. It contains interactive sliders that you can use to vary $n$ over the interval $[0,30]$ and $p$ over the interval $[0, 1]$.
