That was incredible. I watch every video posted on this channel and this one really struck me. Can we get more of this guy? Very interested in what he has to say.
One asks what is the value of one divided by three, then multiplied by three. A mathematician answers "1". A physicist answers "0.999999..." (alternatively "0.99 ± 1%"). A statistician answers "¿ How much would you like it to be ?".
Son-Tchor I Great joke. Though I think programmer would make more sense than physicist. Because physicists often use exact math. While rounding errors are very computer specific fault.
Data mining is just applied statistics... just without a hypothesis to start with. This is why it is much more prone to mistaking random patterns for causal ones.
A great example of a real problem still seen with a lot of scientific studies today. Researchers feel they must have a trend and so draw in a trend line with no real support from the data. Objectivity, integrity and honesty are essential to science.
Once you figure this out, even more complex forms of those Capta's will be needed (the annoying things you have to type when attempting to register for things)
***** A lot of data analysis and mining is done under NDA also if you are working with things like medical records or other personal information you have to worry about the data protection act. He probably forgot to turn off his screen before they did the interview. A place i used to work doing something thing similar although less complex you had to lock you pc even if you were getting up for just a few seconds.
A common problem that analysts encounter is where managers ask for this and that mean or average. They come to us with their solution, not their problem. Thus, they often get what they asked for and not what they wanted;
This guy has a very odd idea of what "statistics" is. No way of dealing with missing or unclean data? No way of uncovering nonlinear relationships? Absolutely not true. He's clearly knowledgeable about statistics but still seems to think these things, which makes me think he just has a weird definition for the term, which is nonetheless very misleading. Interestingly, the causality discussion at the end of the video is currently where machine learning is weakest relative to standard statistical (and especially econometric) methods, so it's a very odd inclusion in a video with a subtitle about being better than pure statistics. Causality isn't completely unadressed in machine learning (see the work of Judea Pearl on causality in ML coming from the computer science side, or Susan Athey from the econometric side) but it's much less well established, and many of the engineering and CS people applying these methods in industry are largely clueless about these advances, or even the concept of causality outside an experimental setting.
He might have been referring to classical statistical methods. It is well established that the field of machine learning is based on and have contributed to statistical learning theory.
Google and facebook do big data mining in much larger scale than professor here actually indicates. To get that data is easy, to piece it up is hard. That's one reason Facebooks aquisition of whatsapp is already profitable for facebook. They got the one piece they didn't have. Phone numbers. Billions of them.
Tim Okolowski it did sound typical german to me though, the way he said "dat" instead of "that". Im from the netherlands though so i might be a bit biased.
It could be that salt has no significant effect on blood pressure and other contributors, such as stress (more stress in industrialized nations), dominate. Finland has the highest rate of heart attacks and 40% of the Finnish diet is derived from fat. But Greece has the lowest heart attack rate and 40% of the Grecian diet is derived from fat...
Skux it's funny how the maximum recommended daily salt douse here is 1g but then you go buy food somewhere where they give you those salt sachets and they come in 2g. Not to mention some foods have more salt than that alone. ....it really is all because of water.
So the main take away from this is that a higher salt diet is a healthy part of a western lifestyle. I didn't expect medical advice on this channel, but I'm altering my eating behaviour right now based on this clear advice :-)
Jacob Parsons Yeah. He had quite an interesting definition of what statistics is. Ignoring perhaps his misnomer, that linear regression near the end horrified me the instant I saw it. I just took the AP Statistics Exam, so all those rules are going through my head.
This guy just called Google a lookup table, that takes balls.

Great joke, but any good scientist would still use the exact values (if the values were exact to begin with) and therefore arrive at 1. :)
Son-Tchor I Great joke. Though I think programmer would make more sense than physicist. Because physicists often use exact math. While rounding errors are very computer specific fault.
Son-Tchor I the last thing you say is part of what a computer algebra system like mathematica does

Hi
Data mining is just applied statistics... just without a hypothesis to start with. This is why it is much more prone to mistaking random patterns for causal ones.
This professors is one of the first germans whose english doesn't make me cringe. I even thought he was british for a few seconds.
Is there anymore info regarding the benefits of higher BP?
This guy should teach statistics. I want more of these videos!
More from him and more data mining please!

What is hidden behind that square over the computer's screen?

GabrielHawkPot Why not just turn off the monitor or minimize the window or something though.

His rarerest rare pepes...
This video was quite interesting. Would love some more videos on this kind of topic and videos with Professor Uwe Aickelin.
The true mystery is: What’s behind the gray rectangle mask over the computer display? We may never know . . .
There are some free MIT lectures on algorithms and AI worth watching.
DJTripleThreat78 Just search for MIT Open Course Ware
This is exactly the guy that came to Unicamp in Brazil to talk about Nottingham's CS research in big data and DIDN'T mention Computerphile! hahaha

Wow, excellent talk about data mining/big data/machine learning. Good job guys!
DRINKING GAME:
Drink every time he says Data
Drink every time he says Artificial Intelligence
In data mining how does one ensure that you aren't a victim of p-hacking, if you gave a sufficiently large data set?
Amusing that a big data video appears a few days after some big data operations in the US are ruled illegal. Or alarming.
Uwe Aickelin sound like just the man for James Harris "Jim" Simons company.

@@tratbagd4500 That's unlikely. Classical statistics does include missing data correction and non linear models, at the very least.
Wow, that thing with blood pressure is quite a cool example!
WTF ? you upload this just when i am writing a paper about data mining ! thanks !
The salt example blew my mind
This video make remind me of tv series person of interest

That's one reason Facebooks aquisition of whatsapp is already profitable for facebook. They got the one piece they didn't have. Phone numbers. Billions of them.
Loved this video, thanks :)
Right, looking up the data isn't that hard for Google, but finding a way to fit a website or image in their tables proooobably is
Not actually
professor Uwe has the most awesome accent ever........ im wondering where hes from.... anyone?
AwesomeVindicator He is from Germany, but in my opinion his accent doesn't sound stereotypically german.
Tim Okolowski it did sound typical german to me though, the way he said "dat" instead of "that". Im from the netherlands though so i might be a bit biased.
He sounds like a friend of mine who is Austrian.
AwesomeVindicator Sounds German to me because that is how I sound as well :p
Braminam haha yea its obvious :D the dutch have the same accent when speaking english as the germans
he is so excited
I like this guy.
Thatssss my professor!!!!!!!!!!!!!!!!!!!!!!!!!!!!
So it's just a different flavour of statistics?
TechyBen he uses the word statistics like "deterministic calculations"
very, very interesting.

Dude, Paper doesn't grow on trees, you know?
Google: it's just a lookup table.
More like this, please.
"I drank water and therefore..." :D
Skux it's funny how the maximum recommended daily salt douse here is 1g but then you go buy food somewhere where they give you those salt sachets and they come in 2g. Not to mention some foods have more salt than that alone.

Google is just a look up table .... ThugLife baby
At first I read dota mining xD

Richard Towers You heard it wrong! He said they measured urine in salt. So stop peeing on your salt!
you can always manipulate a statistic to support an argument
politicians make a living doing it and it appears doctors do as well !!
I WANT TO BE SMART
Data
Y YU NO USE THA BROWN PAPER!??????!!!!!!!!!
***** Haha I think it's an intentional move designed to be sort of complementary to the brown paper. It's the classic old-printer load paper.
***** Brown paper for numberphile this one for computerphile
Nnnnnoice
Statistics != linear regression
Jacob Parsons Yeah. He had quite an interesting definition of what statistics is. Ignoring perhaps his misnomer, that linear regression near the end horrified me the instant I saw it. I just took the AP Statistics Exam, so all those rules are going through my head.
Oh, another example of insufficient popular big data explanation.
Please stop using markers on paper.
I can't understand him every other sentace. He talks too quickly and quietly at times.
Joebro8bit learn to listen its only you it seems
Joebro8bit i had no problem and i'm not even native.
