This quiz says to type in a number, but both times I type in a number, it’s subtracted one from the number I typed when I submitted. So it is wrong regardless of whether I index feature four starting from 0 or 1, because it subtracts one from the value of that feature that I have typed, when I submit the solution.
Could someone please help?
I already went ahead and implemented vectorized linear regression, just while having fun, on one of the week 1 labs. I really don’t need to go through this unit. I have also taught it, as part of a freshman physics lab, at LSU, while a grad student there, in 2014-2015.
I have used linear regression with multiple features in my research as a physicist.
However, the next section right after this quiz has things I would like to learn.
Well that was fixed when I retried (and hopefully will stay fixed) but then it edited what I entered for the third question. I also know why it does/does not find minimums better with larger alpha and did not find that answer ambiguous, though I was nervous that the form would expect a different answer than my own opinion. But I entered my own opinion, and the form seems to agree-- it just changed my answer this time!
