1 Chandan Datta, July 7, 2007 at 9:44 a.m.:

Will this be available as a wmv(Windows Media) rather than only flash streaming sometime later ?

2 davor (staff), July 9, 2007 at 9:32 a.m.:

Hello,
sure, the wmv videos will be available next week.

3 jp, August 3, 2007 at 2:14 p.m.:

Just wondering: it is now several weeks after next week and I cannot find a wmv version. What am I doing wrong?

4 peter (staff), August 9, 2007 at 6:19 p.m.:

We are experiencing some technical problems with disk drive enclosures that we were using during the recording (our external Maxtor tera-byte drives keep overheating and failing causing data loss). It is a sad thing: we will have to completely repeat the whole tape-recording/editing/processing work and it may take a few weeks before it is done. Stay with us...

5 Ajay, August 31, 2007 at 12:30 p.m.:

The flash video continues to load for ever! with no progress. It directly starts at 50% and never moves ahead!
Please post the wmv video asap
Thanks,

6 mikaiel, September 17, 2007 at 9:51 p.m.:

can some one fix the wmv file, or convert the flash to wmv, or tell us how to view the flash. There is noway I can view this video.

7 Ben, September 19, 2007 at 5:42 a.m.:

She is cute, haha

8 Tony, September 27, 2007 at 12:02 a.m.:

I agree. She is pretty cute. =)

9 keller, October 9, 2007 at 10:41 p.m.:

Pls put WMV videos asap!

10 commentator, October 20, 2007 at 7:12 p.m.:

Yeah she's cute, but she's also smart.
And people, stop being pushy about putting up WMVs. sheesh.

11 ML Geek, November 3, 2007 at 11:31 p.m.:

Sorry to post again... can you please also post the pdf of the presentation slides. Thanks a bunch.

12 J, November 8, 2007 at 4:31 p.m.:

Well done. She did a fine job.

13 Shashank, November 10, 2007 at 11:18 a.m.:

Well ,keep up the good work,,, (though i am really waiting for download'ble version of these)

P.S::yes ,she is cute

14 Ramayya, November 19, 2007 at 9:33 p.m.:

How about making the videos available in Open Standard Format such as MPEG. Since WMV is a proprietary format and is not easily viewable on Unix and Linux platforms.

15 macias, November 21, 2007 at 2:08 p.m.:

16 Ruhi bey, November 25, 2007 at 5:15 a.m.:

Great lecture.

Hell yeah, she is cute !! :)

17 suresh, November 26, 2007 at 10:48 a.m.:

18 Jagadeesh, November 30, 2007 at 8:41 a.m.:

We have tough firewall rules on MMS / RTSP.

19 Deepak, December 26, 2007 at 3:08 p.m.:

I think you should also provide a direct link to download these videos in a regular way as a file rather than streaming (i know it will be costly for you to run such web servers, but may be you could do this)...

This will enable and promote sharing among users downloading the video with other people (and this way, it will also act as a mean of reaching more & more audience for your website, as your website address is embedded in very video)....

And isn't Real (.rm) media preferred format for streaming videos on web (have seen wmv as format for streaming videos on researchchannel.org only other than you people. MIT, Berkely etc. all use real media for streaming....Real media takes less space on hard disk for same duration of video...thus saving both disk space and bandwidth)

And finally, these videos are really great....keep up the good work....

20 Gaurav, December 31, 2007 at 4:56 p.m.:

hey... seriously you should consider making them available for download... i have a slower connection at home than at my univ... and the difference is of hell and heaven... please consider putting the videos as downloadable files...

one more CUTE vote :P

21 keta gonzalez, January 2, 2008 at 11:38 p.m.:

but it is easy to record the stream with mplayer.
for example:
mplayer -dumpstream mms://velblod2.ijs.si/2007/pascal/bootcamp07_vilanova/keller_mikaela/bootcamp07_keller_bss_01.wmv -dumpfile /somedirectory/keller_mikaela_01.avi

to get the mms:// adress look at the page source of the corresponding video page

keta

22 Terence Toh, January 5, 2008 at 11:29 a.m.:

just download the free Real Player, and select on the file settings so that Real Player is the default program to play the streamed file. The beauty of Real Player is that it's got a built-in 'Download This Video' from streamed files. I've tried it and it's perfect.

23 Terence Toh, January 5, 2008 at 3:07 p.m.:

or just type 'internet video recording' into the Google search and voila...

24 Argentens, January 5, 2008 at 6:40 p.m.:

Bien changé depuis "dedans-dehors"...

25 macias, January 12, 2008 at 1:01 p.m.:

Btw. just in case, a little script that maybe helps:

#!/bin/sh

if [ -e "\$2" ]
then
kdialog --title "File already exists" --warningyesno "Overwrite?"
if [ \$? -eq 1 ]
then
exit 1
fi
fi

mplayer "\$1" -dumpstream -dumpfile "\$2"

26 MB, March 18, 2008 at 8:08 a.m.:

Tres jolie!

27 Error!, March 30, 2008 at 8:50 a.m.:

Slides for PART 4 DO NOT MATCH the talk! The slides are from part 3 ... even for part 4 ...

28 Chris, May 25, 2008 at 1:14 a.m.:

Sorry for students at your university, bootcamp or wherever it was recorded! The Lecturer can't speak English and she is really bad at explaining the concepts!

29 Guru, May 29, 2008 at 6:13 p.m.:

Is Superb.....

30 Eric Hamilton, June 22, 2008 at 10:38 p.m.:

This is a great topic, and she does a good job of explaining it.

I can see why this is a popular lecture. ;)

31 not good enough, July 2, 2008 at 4:07 p.m.:

the lecture was not good enough. poor english.

32 anon, July 10, 2008 at 6:36 p.m.:

This is a great resource but incomplete with notes for talks 3 and 4 are missing or pointing at wrong slides. It is very hard to make notes as the camera often points away from the board or misses the bottom equations during critical parts of the explanation. I recommend reading Bishop alongside it as many of the concrete examples are in there too.

33 anil, August 29, 2008 at 5:33 a.m.:

Superb lecture. Ofcourse she is cute; and smart too. Can't blame the cameraman. Thanks for the lectures.

34 Hoshin Gupta, October 6, 2008 at 7:45 p.m.:

The slides for Lecture 4 are missing. Can you post them please? Thanks.

35 sreenu, November 11, 2008 at 9:30 a.m.:

sir please send the basics of ps

36 ALI ADAM, November 20, 2008 at 8:49 a.m.:

I listen the one of the teachers truely i can'nt express how i find it

37 tassos, December 1, 2008 at 12:03 a.m.:

great lecture! bring more female scientists in!

38 Andraz, January 22, 2009 at 10:49 p.m.:

A quick review (after viewing all 5 parts):
a) there are places where the flow is great and she gets things across
b) unfortunately many times she jumps between topics and viewer is baffled with what is going on
c) improving her English wouldn't hurt. trying to comprehend what words she is saying takes away time from comprehending what she is actually explaining
d) camera is bad. instead of moving to the slides camera stays on her face. also parts of the screen are clipped away.

she's cute and fuzzy, but still this could be done much better and the viewer could digest much more in the time all this videos take. Still she has put in very good effort and I applaud to that.

bye

39 Sasi, February 17, 2009 at 12:45 p.m.:

or
where to get this video lecture in wmv or any format?

mail me sasikanth.v19@gmail.com

40 DaPilma , February 20, 2009 at 9:41 p.m.:

How did you achieve the synchronization of video with the slides. Is there a a need for a particular application to achieve this?

41 Paul Haynes, April 6, 2009 at 10:34 p.m.:

Hi,

The slides for presentation 4 are the same as those of the more advanced topic in presentation 5.

Could you please post the correct slides for presentation 4?

Many thanks,
Paul

42 Paul Haynes, April 6, 2009 at 10:35 p.m.:

PS by slides i mean the "downloadable" slides, not the slides which automatically accompany the video footage.

Thanks,
Paul

43 PhD Student, April 16, 2009 at 11:22 p.m.:

She is so HOT!
I am a PhD in ECE, and this is the hotest scientist I ever seen before.
Thank you!

44 Miguel Angel, April 19, 2009 at 3:06 p.m.:

She is having a really hard time expressing herself in english.
Those who complain about her english, I'm sure you are able to express yourselves in french or spanish better, aren't you?
Great lectures.
Many thanks.

45 ewa, May 4, 2009 at 7:33 a.m.:

The fact that the lecture is good just makes her more cute. But man is she cute.

46 Iveco, July 30, 2009 at 8:42 a.m.:

I don't know what do you see beside bad lectures if you use them as comparison with TED.

47 Matrix, September 17, 2009 at 3:43 a.m.:

So cute, I love her.

48 lola, September 23, 2009 at 5:47 p.m.:

that is perfect

49 Gaspard Bucher, October 7, 2009 at 1:32 p.m.:

I've never seen a bunch of guys saying "oh man, is he cute" on a man's presentation. If one of you ever posts a video, I'll write "I love him", "he is so cute" on every two comment so you get the feeling of what you are doing.

You behave like machos and wonder why there are so few girls in computer science...

50 Baly Balo, October 19, 2009 at 8:13 p.m.:

Yeah! She's very pretty! I think she's french...
Furthermore it's a great course.

51 jon, October 30, 2009 at 2:43 a.m.:

great lecture!! is refreshing to not have a prof bugged down in high level of abstraction. and super cute >__<

thks

52 Kipara01, November 29, 2009 at 11:56 p.m.:

Very interesting course Wah!!

53 Kipara01, November 30, 2009 at 12:01 a.m.:

I missed a lot in this world of sciences am behind in all.but I need to speed up I hope all of you are ready to help me to pull me and make me get on that bridge. Am I sense?

54 learner, December 3, 2009 at 4:43 a.m.:

I'm a student in mainland China,due to obivious reasons,the communist party censors everything on the internet, and the network serve provider in my country offers poor speed connections(yet expensive),so I have a big problem watching this video, would you please send me the downloadable links so that I can download it and watch it locally? I promise you will not encount any legal problem, cause intelligence protection in my country(is that correct?) is poor, too

55 learnr, December 3, 2009 at 4:45 a.m.:

I forgot my email:luoyu.chn@gmail.com

56 nanang krisdianto, December 10, 2009 at 7:18 a.m.:

dear sir,

is there a possibility to make these(not only this video)
downloable version?

so that we could learn this offline (lot of us had poor connection)

in line with this slogan
"The main purpose of the project VideoLectures.Net is to provide free and open access ....."

for development and share of knowledge

thanks

57 mika, December 13, 2009 at 1:52 a.m.:

"coorelation between time and eruptions." in my pants.

shes hot and not wearing a bra but this is garbage.

oh! she was saying "Machine Learning." that changes everything!

59 Peter, December 25, 2009 at 4:07 p.m.:

part 4 and 5, without slides in a second window, are hard to follow. The camera is on her face while she is pointing at the slides and you may only wonder what she is pointing at. The downloadable slides graphm1.pdf are too different. - Are you brushing up part 4 and 5 to the standard of parts 1-3

60 seyed, February 18, 2010 at 9:03 a.m.:

61 PoopMonster, April 1, 2010 at 11:21 p.m.:

If any of you still want them please post a request here and I will provide you with the links.

Do you mind if I post the MEDIAFIRE links here? Is it legal to share videos from "videolectures.net"?

62 James Smith João Pessoa, Brazil, April 6, 2010 at 8:57 p.m.:

Remember the words of Mark Twain, "There are lies, damned lies, and statistics". Or, as my own father told me, "Figures don't lie, but liars can figure."

Yes, she is a hottie. :D

63 PoopMonster, April 16, 2010 at 12:37 a.m.:

64 bilal, May 6, 2010 at 9:28 a.m.:

gud lecture,,,,,,mam

65 yves, May 30, 2010 at 9:44 p.m.:

Teaching really is a different track. Every PhD shouldn't try to teach beacuse they have written a dissertation on that topic it doesnt mean that they can teach very well.

For the ones gilbert strangs linear algebra courses covers these topics extremely well. This lady is very bad at teaching and incomprehensible.

66 yves, May 30, 2010 at 9:48 p.m.:

Also we need ugly teachers man this woman is damn hot chick.

67 energy monitoring, July 6, 2010 at 2:54 p.m.:

really cool video lectures

error on the example on determinant

70 huayue, August 15, 2010 at 1:25 a.m.:

many mistakes such as in the SVD slide

71 jpthank, October 22, 2010 at 10:38 p.m.:

this lady is damn hot. cool

72 jpthank, October 23, 2010 at 1:46 a.m.:

where is the presentation 4? the pdf file is missing?

73 jpthank, October 23, 2010 at 2:36 p.m.:

she should teach in french rather than in english. anyway, she is cute and hot.

74 jpthank, October 24, 2010 at 7:35 p.m.:

P(S=1|W=1) = 0.43? P(S=1|W=1,R=1) = 0.19?

my result are 0.473 and 0.3204. Can anybody help
me out?

75 Marc, November 19, 2010 at 3:33 a.m.:

In part I, she says that if we want to calculate M², we can write M²=M*M but I think it is wrong, we have to write M² = t(M)*M where t(M) is the transposed matrix.

76 anjali, March 15, 2011 at 3:09 p.m.:

Hi,Its avery good lecture.I also saw such a good lecture
www.univexcellence.com do check videos there as well.

77 Chrisk, June 15, 2011 at 12:44 a.m.:

She sucks. The information is very low-yield. Go back and review linear algebra. Learn to speak English too.
