Nuggets of Data Gold - Computerphile

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

WTF ? you upload this just when i am writing a paper about data mining ! thanks !

Y YU NO USE THA BROWN PAPER!??????!!!!!!!!!

he is so excited

Loved this video, thanks :)

professor Uwe has the most awesome accent ever........ im wondering where hes from.... anyone?

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...

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

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

I generally like your videos, but this one felt a little... Boring? I am not sure, but I expected something more on the content. Nevertheless I expect a follow up video as usual, which might contain more of what I expected :)

This guy should teach statistics. I want more of these videos!

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.

There are some free MIT lectures on algorithms and AI worth watching.

Statistics != linear regression

So it's just a different flavour of statistics?

Uwe Aickelin sound like just the man for James Harris "Jim" Simons company.

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.

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)

you can always manipulate a statistic to support an argument
politicians make a living doing it and it appears doctors do as well !!

I can't understand him every other sentace. He talks too quickly and quietly at times.

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.

That last bit is pure gold. I couldn't see that correlation is negative. But it was clear from the start that the conclusion they draw was bullshit. It's clear form the outset that it's two groups. How researchers who done the study couldnt see it through or even stop a second and say "hold on, something's not right" is beyond me...

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.

Amusing that a big data video appears a few days after some big data operations in the US are ruled illegal. Or alarming.

Wow, that thing with blood pressure is quite a cool example!

"I drank water and therefore..." :D

Wow, excellent talk about data mining/big data/machine learning. Good job guys!

Is there anymore info regarding the benefits of higher BP?

Please stop using markers on paper.

Google: it's just a lookup table.

I WANT TO BE SMART

This guy just called Google a lookup table, that takes balls.

DRINKING GAME:
Drink every time he says Data
Drink every time he says Artificial Intelligence

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 :-)

This video was quite interesting. Would love some more videos on this kind of topic and videos with Professor Uwe Aickelin.

I like this guy.

Dude, Paper doesn't grow on trees, you know?

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.

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.

very, very interesting.

More from him and more data mining please!

More like this, please.

Google is just a look up table .... ThugLife baby

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;

Data

This video make remind me of tv series person of interest

In data mining how does one ensure that you aren't a victim of p-hacking, if you gave a sufficiently large data set?

Oh, another example of insufficient popular big data explanation.

The salt example blew my mind

Thatssss my professor!!!!!!!!!!!!!!!!!!!!!!!!!!!!
