He seems to be a really great professional, but it is
clearly that he is talking to himself while he teaches, he
makes the question he answers them. I have not listen any of
the students say anything, he just keep writing, talking. He
is just speaking to himself aloud, that is why mathematics
feels as it is so difficult, but in reality it is that very
few are able to transmit their knowledge.

Truly excellent video course by the master. Lecture 14 does
not cover the SVD even though the title says it does.

Truly excellent video lectures from the master. Lecture 14
though only mentions SVD in the title not in the content.
