Probablity distribution on X
I was looking over lecture #2. The following statement was made:
"You use probablity to assume points x(1) up to x(n)" From slide 9 (lecture 2), this seems to infer that the training samples are generated from the probability distribution. Am I correct in my understanding? Before proability was introduced, it seemed that we were discussing training samples as representing actual customer data such as (salary, years in residence, Years at job,etc). I am having some trouble understanding how the probability assumes points on x and what this really means. Is this sort of like a random generator? Any thoughts would be earnestly appreciated.

The assumption is benign since no restrictions are made about what kind of distribution it is, and we don't even need to know what the distribution is. It is just a mechanism that allows us to invoke probabilistic analysis, which is needed to establish the feasibility of learning as discussed in the lecture.

Re: Probablity distribution on X
This clears things up!! Thanks for the quick response. I guess I was stuck in the mode of thinking in terms of real data based on actual applicants. Many Thanks!!
