W2 transcript errata

I noticed some mistranscriptions in the transcript (subtitles, captions) for the course videos. Below is the errata for the 2nd week. I’ll post the errata for the other weeks in those groups.

The format for the errata is as follows. The approximate time is in braces, then the mistranscribed word or phrase follows, followed by a hyphen, then followed by the correct word or phrase. So like this:
[time] mistranscribed word or phrase - correct word or phrase

Video 3 - vectorization part 2

[3:33] Encodes - in code
[3:37] Encodes - in code
[4:14] Factorization - vectorization
[5:41] Encodes - in code

Video 5 - feature scaling part 1

[0:05] Great inter sense - gradient descent
[3:27] Grading descent - gradient descent

Video 6 - feature scaling part 2

[0:09] Skill - scale

Much appreciated.
