Free Bayesian Statistics Textbook

Think Bayes by Allen B. Downey is another free book available from Green Tree Press. Allen B. Downey is a computer science professor at Olin College. The book is currently available in PDF or HTML. The book is not yet complete, so it may contain some errors.

What is a Data Scientist?

A nice short and sweet video about what a data scientist is. Josh Wills of Cloudera defines a data scientist as follows:

Person who is better at statistics than any software engineer and better at software engineering than any statistician.

I would say that definition is pretty good.

Real-Time Machine Learning for Industry

Michael Cutler, cofounder of TUMRA, gave a nice talk to the University of Oxford Computer Science Department. The following quote from his talk sums up his idea.

Given a choice between a “best guess” now, and a “marginally better” answer later, I’d take the best guess every time.

Many times, academic people focus a lot of attention on improving the accuracy of an algorithm, when the resulting solution is too slow for industrial purposes.

How Good Is Your Medicine?

This is a great talk about how much clinical trial data is never published. It is a bit scary but definitely something people should be knowledgeable about.

Alasdair Allan Strata 2012 London

Alasdair Allan gives a very entertaining talk. I love what he did with his hotel room lock, or rather what he “absolutely not under any circumstances …” did with his hotel room lock.

Strata London 2012 Videos

If you were not able to attend the Strata 2012 London conference, have no fear because the Strata 2012 London videos are available online. I believe all of the keynotes and some additional interviews are all available. Engineering Practices in Data Science

This is a great post by Chris Clark of Kaggle. It explains some of the primary differences among engineers and statisticians.
Both groups have something to learn from each other. Engineering Practices in Data Science.

Mind Reading And Data Science

I am not a huge fan of mind reading, but this video is good. Watch the whole thing now. It is only about 2 minutes long.

If you watched the whole video, you will get the connection to data science.
Thanks to Mark Nickel for sharing a link to where the video was originally posted.
