I noticed some mistranscriptions in the transcript (subtitles, captions) for the course videos. Below is the errata for the 3rd 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. Like this:

[time] mistranscribed word or phrase - correct word or phrase

video 1 - regression with a perceptron

[0:12] creating dissent - gradient descent

[1:31] protect - predict

[3:52] when - what

video 7 - classification with a perceptron - calculating the derivatives

- the whole video transcribes “∂” as “dia”

video 9 - classification with a neural network - minimizing log-loss

[0:06] great in descent - gradient descent

[7:49] off - of

video 11 - Newton’s method

[0:06] grading descent - gradient descent

[0:45] grading descent - gradient descent

video 12 - Newton’s Method: An example

[0:08] reading descent - gradient descent

video 13 - second derivative

[3:29] the river - the derivative

[9:12] wave - derivative

video 16 - Newton’s method for two variables

[1:18] around variables - for n variables
