"the following is a conversation with Christos Kudrow vice president of engineering at Google and head of search and discovery at YouTube also known as the YouTube algorithm YouTube has approximately 1..."

"most popular search engine behind Google of course we watch more than 1 billion hours of YouTube videos a day more than Netflix and facebook video combined YouTube creators upload over 500 thousand ho..."

"continue to enrich people's lives then you know then it has to grow with them and and people's interests change over time and so I think we've we've been working on this problem and I'll just say it b..."

"talk about the machine learning of that but I have to linger on things that neither you or anyone have an answer to there's gray areas of truth which is for example now I can't believe I'm going there..."

"settle that choose a side or anything like that what we're trying to do is make sure that the the people who are expressing those point of view and and offering those positions are authoritative and c..."

"comments based on whatever based on how much they contribute to the healthy conversation let's put it that way then the other is almost an interface question of how do you how does the Creator filter ..."

"people here YouTube in a room sitting and thinking about what is the nature of truth what is what are the ideals that we should be promoting that kind of thing so algorithm versus human input what's y..."

"you have a sense that these human beings have a bias in some kind of direction sort of I mean that's the interesting question we do sort of in autonomous vehicles and computer vision in general a lot ..."

"protected class for instance thank you for exploring with me some of the more challenging things I'm sure there's a few more that we'll jump back to but let me jump into the fun part which is maybe th..."

"but there are much more sophisticated things where we're mostly trying to do some syntactic match or or maybe a semantic match based on words that we can add to the document itself for instance you kn..."

"well I'm a researcher in in the US and and when I'm looking for academic topics I want to look I want to see them in English and so she searched for one found a video and then looked at the watch next..."

"on YouTube then you can start to say okay well you know which videos which which other vectors are close to me and to my vector and and that's one of the ways that we generate some diverse recommendat..."

"something else well you mentioned commenting also sharing the video if you if you think it's worthy to be shared with someone else you know within YouTube or outside of YouTube as well either let's se..."

"then I like this person I really want to support them that that's how I click Subscribe right even though I may never actually want to click on their videos when they're releasing it I just love what ..."

"the content analyzing the content while video right and what I can tell you is that our ability to do it well is still somewhat crude we can we can tell if it's a music video we can tell if it's a spo..."

"away from wit and humor so you have to play with both right so but you're saying that for now sort of the content of the title the content of the description the actual text is is one of the best ways..."

"stuff discoverable I think is what you're really working on and hoping so yeah so from your perspective to put stuff in the description and remember the collaborative filtering part of the system it s..."

"life will be better and that's that kind of reasoning I'm not sure what that is and I'm not sure how many people share that feeling it could be just a machine learning feeling but at that point how mu..."

"what a success look like in terms of the algorithm creating a great long-term experience for a user or put another way if you look at the videos I've watched this month how do you know the algorithm s..."

"so on well so that's that's that's a heck of uh the thought that's one of the most beautiful and ambitious I think machine learning tasks so when you look at a society as opposed to any individual use..."

"society already there's a lot of what do you mean by openness well the fact that unlike other mediums there's not someone sitting at YouTube who decides before you can upload your video whether it's w..."

"changing society so I've worked at YouTube for eight almost nine years now and it's fun because I meet people and you know you tell them where they where you work you say you work on YouTube and they ..."

"realize that YouTube is really about the video and connecting the people with the videos and then everything else kind of gets out of the way so beyond the video it's an interesting because you kind o..."

"creative ideas that someone has okay I think it's a really important thing to sort of to dispel I think it applies to all of social media like literally I've taken a break for a day every once in a wh..."

"things in in sort of more fine-grained situations and I and I think that this is the way that the recommendation system and the search system and and probably many machine learning systems evolve is y..."

"over time and so I think that just like with diversity you know I think the first diversity measure we took was okay not more than three videos in a row from the same Channel right it's a pretty simpl..."

"thing well you mentioned that a B experiments and so just about every single change we make to YouTube we do it only after we've run a a B experiment and so in those experiments which run from one wee..."

"it's improving the situation for viewers but we can also look at other things like we might do user studies where we invite some people in and ask them like what do you think about this what do you th..."

"oftentimes we look at where the traffic was coming from you know if it's if it's a lot of the viewership is coming from something like Twitter then then maybe it has a higher chance of becoming viral ..."

"like like I mentioned I hung out with Derek Muller a while ago a couple of months back he's actually the person who suggested I talk to you on this podcast all right well thank you Derek at that time ..."

"like it I mean we can surely see where it was recommended where it was found who watched it and those sorts of things so it's actually sorry to interrupt it is the video which helped me discover who D..."

"happened now you asked me about how to make a video go viral or make a viral video I don't think that if you or I decided to make a video about 96 million balls that it would also go viral it's possib..."

"the the podcasts are doing yeah do you see as opposed to like I also add time stamps for the topics no people want the clip do you see YouTube somehow helping creators with that process or helping con..."

"this a few times so I've uploaded myself it's a horrible idea some people enjoyed it but whatever the video of me giving a lecture in 360 over 360 camera it's cool because YouTube allows you to then w..."

"how you get that from people just watching except they tuned out at this point like it's hard to measure this moment was super exciting for people I don't know how you get that signal maybe comment is..."

"people to just label it yeah you mentioned that we're quite far away in terms of doing video analysis deep video analysis ago of course Google YouTube you know we're quite far away from solving autono..."

"often pretty small right like you know you need to see this person's number in order to know which player it is and and there's a lot of players or you need to see you know the logo on their chest in ..."

"this is the way to go so see you from the perspective of just working with this video how do you think an algorithm that just watches all of YouTube stays up all day and night watching YouTube will be..."

"compression so the idea is tradition when you think of video image compression you're trying to maintain the same visual quality while reducing the size but if you think of deep learning from a bigger..."

"quarter of the way so on that topic what does YouTube look like ten twenty thirty years from now I mean I think that YouTube is evolving to take the place of TV you know I grew up as a kid in the 70s ..."

"you see creators creating visual experiences and virtual worlds so if I'm talking crazy now but sort of virtual reality and entering that space there's that at least for now totally outside of what Yo..."
