Analytic applications are built by data scientists

Ventana Research analyst David Menninger was on the judging panel for the Applications of R in Business contest. In a post on the Ventana research blog, he offers his perspectives on the contest, noting that

R, as a statistical package, includes many algorithms for predictive analytics, including regression, clustering, classification, text mining and other techniques. The contest submissions supported a variety of business cases, including, among others, predicting order amounts to optimize manufacturing processes,  predicting marketing campaign effectiveness to optimize marketing spending, predicting liquid steel temperatures to optimize steel plant processes and performing sentiment analysis of Twitter data.

(Incidentally, David also has a great riff on the terminology of "predictive analytics" and "big data" out today.) He also notes that these applications are compelling precisely because of the close relationship between the contest entrants and the business problems they demonstrated how to solve:

The entries also demonstrated a best practice: close alignment between the analyst and the underlying business objectives. Predictive analytics is not magic. It requires an understanding of business processes and an understanding of statistical techniques. The judging criteria reflected this requirement as well. One of the three categories we were asked to score was applicability of the submission to business. I think it’s clear how the analyses in the winning entries could provide significant business value.

As David notes, however, the counterpoint to this is that the analyst must combine *both* the . "How many people in your organization could perform those types of analyses", he rightly asks. A combination of statistical tools along with domain expertise (plus the technical skills to implement the solution) is the hallmark of a good data scientist, which exactly why many organizations are looking to build effective data science teams.

By the way, while the concept of "data scientist" is relatively new, this idea of combining statistical analysts with domain expertise is not. Bill Cleveland (yes, that Bill Cleveland) made similar suggestions in a prescient paper back in 2001: "Data Science: An Action Plan for Expanding the Technical Areas of the Field of Statistics".

New R User Group in Cambridge, UK

Yet another new local R user group has launched this month, this time in Cambridge, UK. Cambridge RUG was created by data analyst Andrew Caines to promote the use of R in the Cambridge area. 

The group aims to encourage people try the R language, act as an advice centre to help people get where they want to with R and host an annual gathering for R-based talks and workshops. The group's just getting started, if you're interested you can join the group email list to be notified of upcoming events.

Pre-conference tutorials announced for useR! 2012

The worldwide R user conference, useR! 2012, will take place this year June 12-15 in Nashville, Tennessee. In addition to the regular program of invited and contributed talks, a highlight of every useR! is the pre-conference tutorials: hand-on, half-day in-depth expert-led sessions with a focused on a specific area of methodology with R. This year's roster of tutorials has been announced, with topics such as reproducible research, parallel programming, medical image analysis, Hadoop, predictive modeling, and many more. 

And as an extra-special bonus, Bill Venables (of Introduction to R fame) will present a one-day course on June 11. This session will be a "gentle survey of modern data analysis, graphics, and statistical modeling in the style of Modern Applied Statistics with S, Venables' classic textbook with co-author Brian D. Ripley, including developments both in R and statistics since the latest edition." Bill is one of the greatest tutors on statistics and R (he taught me most everything I know), so this is definitely not to be missed.

Tutorials often sell out, and early-bird registration for the conference is now open, so be sure to register early to secure your place.

Because it's Friday: Movie Poster Cliches

The principle of "small multiples" — displaying multiple charts of the same type to compare differences — was introduced by Bill Cleveland and popularized by Edward Tufte and the "lattice" package in R. Now, the same principle is applied to movie posters in this display of "Over-Used Movie Poster Clichés":



Apparently, a couple standing back-to-back on the poster is a good indicator of a tough-love relationship between the protagonists, and an all-yellow background indicates an adorable indie-flick. Follow the link below for more examples:

New R User Group in Cleveland

Another new local R user group has just started up, this time in Cleveland, OH. The Cleveland R User Group is the brainchild of R user Nicholas Hermez, and their first meeting on February 22 is a get-together to plan future topics, presenters and venues. If you're in the Cleveland area why not drop by and contribute your ideas?

By the way, don't forget that both existing R user groups and new R user groups like the Cleveland group are eligible for sponsor that sponsorships from Revolution Analytics.

Statistics: one of the cool kids

As I've mentioned before, I've always found it a little awkward to introduce myself as a Statistician -- it's not exactly the greatest conversation-generator at cocktail parties (or it just turns conversation to baseball, especially post-Moneyball). So it's nice to see that this is changing, as one of my heroes in Statistics relates:

“Most of my life I went to parties and heard a little groan when people heard what I did,” says Robert Tibshirani, a statistics professor at Stanford University. “Now they’re all excited to meet me.”

I've wholeheartedly embraced "data scientist" as a term because, frankly, it's had more sex appeal than "statistician". Good to see this is changing, and now maybe I can  be an out-and-proud Statistician.

Congratulations to both winners, who were selected by a judging panel of industry experts, analysts, and R users. (The competition was also very close: there was only a coupe of points in the judges' aggregate scores separating the top two entries.) 

In addition, the following applications were selected for $1,000 Honorable Mention prizes by Revolution Analytics:

• Hakan Koç and Bengt Maas, Salzgitter Mannesmann Forschung GmbH: Towards an ideal steel plant - Online liquid steel temperature prediction using R

Thanks to everyone who participated in the contest. A special mention is due to Shannon Terry and Ben Ogorek, both from Customer Analytics within Nationwide Insurance. They have been gracious enough to donate both their grand prize and honorable mention prizes to charity Mid-Ohio Foodbank, a 501(c)(3) organization based in Columbus, OH and a close community partner with Nationwide Insurance, will receive $11,000 to support their efforts in hunger relief. What a wonderful contribution!

BBBT Podcast with David Smith

Last Friday I was fortunate enough to have the opportunity to travel to Boulder, CO and present R and Revolution Analytics to about 20 analysts as part of the Boulder BI Brain Trust (BBBT). It was a great pleasure to describe the vision for Revolution R Enterprise and got some great feedback from the particpants.

During the event, I had a great 10-minute conversation with BBBT president and founder Claudia Imhoff about the R project, how Revolution R Enterprise is used, and the future of Revolution Analytics. The podcast is now live on the web, and you can listen to it at the link below.

New R User Group in Belgium

RBelgium is the latest local R user group to join the R community. Led by R user Jean-Baptiste Poullet, the group will host meetings on the first Friday of each month at the Alfot Hotel in Brussels, as well as weekly coffee get-togethers. The group also provides an on-line discussion forum on statistics and applications with R. 

You can find more information and join the group at MeetUp site linked below.

Because it's Friday: Movie stars sing 'Hello'

This is just wonderful:

From the description, I'd assumed that the movie clips would be autotuned to the song, but that appears not to be the case. Matthijs Vlot spent a lot of time finding lines of (approximately) the right pitch here. I predict many other songs will follow in this vein.

Have a great weekend!
