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, 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.

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.

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.

***** 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.

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.

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...
