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 - vector space models
[0:04] base - Bayes
video - euclidean distance
[0:27] corporate - corpora
video- visualization and pca
[0:48] higher than to - higher than two
[0:52] sitting in town - city and town
[2:40] any lower - in a lower
[2:51] one correlated - uncorrelated
video - pca algorithm
[0:30] vectra - vector
[0:49] that’s NPCA - that in PCA
[0:57] You give - They give
[1:21] then medical variance - then get the covariance
[2:04] dust products - dot products
