At the risk of not sounding very clever, I have to admit it's way too fast for me

That's the thing with these "tutorials". I remember watching one video that was "Calculus in 5 mins". It made a lot of sense, but that was after learning it, but to someone who's never been taught the topic, these might not make any sense

It's not a binary difference between learned and untaught. Many people have taken calculus classes and probably not enjoyed any lasting insight, either because the teaching was bad, or there were too many other subjects swimming around their mind at time. Or never taken a class but developed a surface familiarity with the main ideas. These types of tutorial could be useful for them.

I am very interested in this subject but I was unable to finish watching these videos. The background music is incredibly distracting. I have a name for that kind of music, I call it Silicon Valley Music because it is the kind of music used in a lot of startup product videos. The narrator voice style is also pretty much the same that is used in those. I wanted to like these videos but I did not feel that they had any…

yes music needs to part ways from otherwise interesting video

To demystify NNs further we need to stop graphically representing spurious interactions. If you can perturb or remove a link win between any two neurons i & j, then that interaction is spurious and shouldn't be represented by in the graphical network representation. Doing this iteratively you can start to better appreciate that neural networks are computational circuits that use thereshold functions instead of logic…

To me 'demystifying' really means making simpler to understand. Yours sounds like technical pedantry, that while true (idk?) is meaningless to anyone who actual needs a neural net demystified.

I'm confused by your comment. You seem to be saying two different things:

1) The music and choice of narrator is getting in the way of the (presumably valuable) content.

2) The content itself, regardless of the choice of narrator or whether or not there's music behind it, is not useful.

If it's the latter then why complain about the former?

Hey, everyone! I'm the founder of lumiverse.io, it's pretty incredible to see our website on the front page of HN! I want lumiverse to become an awesome community where people can discover and discuss great educational videos. We've launched only recently, the site is still in active development, I'm improving it every day. If you have any feedback - please let me know =) (Also feel free to contact me at raymestalez@…

nice work, i am interested in this kind of information, but i am no big fan of the edutainment video format, i prefer text or a university lecture. some feedback about the first video: - why the music? should this be information or an awfully mixed guitar rap song with the worst flow ever? i can't stand the use of elevator music in these kind of videos and also regard this kind of video production as an act of disres…

Personally, I liked the music. Maybe the music could be optional. Might be a cool feature to add, if there's time.

These are great videos, and the content itself is, in my opinion, pretty good.

It seems to me these have been narrated by a professional. The narrator's voice is pleasant and pronunciation clear, but it seems he doesn't really know what he's talking about.

I would prefer the voice of an actual subject matter expert; they would be able to better convey which parts are actually key concepts, and which parts are just intermediary math. Now it feels like everything is equally important, when it's clearly just some intermediary math to get you to the actually interesting part that follows.

I agree that the continuous music is distracting. The quick fix is to fade the music away for the content. It would be fine to leave in for the beginning, end, and transitions.

These are also available on Stephen Welch's youtube channel[1]. He uploaded the last one in this series Janaury 2015. [1]: https://www.youtube.com/playlist?list=PLiaHhY2iBX9hdHaRr6b7X...

Per guidelines : https://news.ycombinator.com/newsguidelines.html Please submit the original source. If a post reports on something found on another site, submit the latter. The youtube URL you cited would probably be a better source link.

Yes, it was misleading I thought all these videos were original content of that site; in fact, they are original content produced by Welch Labs: http://www.welchlabs.com/
