There’s this branch in computer science and statistics for vision research. Normally, if you ever hear about it in the news it’s in the context of spotting terrorists in security tapes or facial recognition checkpoints (you know, like what they have in movies in front of giant steel doors). That is of course not the only application.

Google (and many others) has been playing around with this stuff for a while. Most recently, they released Google Image Swirl in their labs section, which utilizes computer vision to find similar images.

Above is my search for happy cat. The initial search result is what you’re used to. It’s a matrix of thumbnails. Click on one of them, and you’ll get similar images clustered as a network graph.

Google Image Swirl: the new way to find if someone is plagiarizing your work.

I’m no doubt still under massive food coma at this time, but in case you’ve regained consciousness or don’t live in the US, check out this collection of maps from The Morning News. Can you guess what each is supposed to show? If you can guess even one of them correctly, I’ll be impressed.

[Thanks, William]

What is FlowingPrints?

For those new to FlowingData, FlowingPrints is a pet project of mine to put data, well, in print. For this first series, I collaborated with two designers to create three original views of education in America – through data. Check ’em out now. They’ll make your walls ridiculously smart.

Food-wise, Thanksgiving is different across the country. In some places you’re going to get a lot of chitterlings and collard greens, while in others, turkey and mashed potatoes. Personally, I’m a big fan of the 10-course Chinese feast, but to each his own.

The New York Times (Matthew Ericson and Amanda Cox), map what’s cooking in your neck of the woods based on searches on Allrecipes. The top search, concentrated in the southeast, was sweet potato casserole. I have no idea what that is, but it must be delicious.

What? I don’t see anything wrong with it.

Verizon has been running these ads lately that compare their 3G coverage to that of AT&T’s. In the ads a Verizon customer walks along on a speedy phone, and a US map pops up that’s covered in red. Later, an AT&T customer looks frustrated with a sparsely-covered AT&T coverage map. You’ve probably seen them by now, but if not, here are the Verizon ones.

GE and Ben Fry (now the director of SEED visualization), show the cost of getting sick, from the individual’s and insurer’s perspective. The data: 500k records from the Medical Expenditure Panel Survey from GE’s proprietary database. The visualization: a polar area pie chart.

This comic was really amusing, although it might be because I’m a big nerd entertained by all things from PHD Comics…

It’s my blog, and I can laugh if I want to.

Have a nice weekend, everyone.

[Thanks, Stephen]

Thank you to the FlowingData sponsors for keeping the servers alive. Without them, this blog would not be possible, and I wouldn’t be able to do what I do.

Check out what they have to offer. They make your data useful:

Xcelsius Present — Transform spreadsheets into professional, interactive presentations.

NetCharts — Build business dashboards that turn data into actionable information with dynamic charts and graphs.

InstantAtlas — Enables information analysts to create interactive maps to improve data visualization and enhance communication.

Tableau Software — Data exploration and visual analytics for understanding databases and spreadsheets that makes data analysis easy and fun.

Email me at nathan [at] flowingdata [dot] com if you’d like to sponsor FlowingData, and I’ll get back to you with the details.

Interaction designer Christian Swinehart takes a careful look at the popular Choose Your Own Adventure books from the 1980s. We saw something like this before, but Swinehart takes it a step further.

Imagine a world where data becomes the everyday, simply embedded in what you normally do. It’s really not far off if you think about it. We use charts, graphs, and viz to make important decisions with investments, businesses, and to stay informed on the news, so why not use it in our own lives?

Last week I posted some parallel coordinate plots that related SAT scores and class size. Now it’s your turn to take a crack.

You can find the data that I used (and more) from the National Center of Education Statistics. There’s a link to download the data as an Excel file. You can find pupil/teacher ratios here.

The two best entries each win a copy of David McCandless’ The Visual Miscellaneum: A Colorful Guide to the World’s Most Consequential Trivia as well as eternal glory on FlowingData. Yes. Eternal.

David McCandless’ The Visual Miscellaneum: A Colorful Guide to the World’s Most Consequential Trivia hit the shelves last week (in the US). As I flipped through 320 pages of original graphics during my flight from New York to California, I thought to myself, “FlowingData readers are going to love this.”

Ever since my hometown Fresno, California was ranked the dumbest city in America (albeit, with a flawed ranking system), the first FlowingPrints series, on the state of education, has taken on new meaning. It became personal, and then it occurred to me that it should be personal for everyone. I think most of us know how important a good education is.

Needless to say, my old high school and middle school now each have a copy of the series. My mom hand-delivered them (thanks, Mom). I’ve also been sending prints to schools, libraries, and education departments across the country near those who have already bought prints for themselves (thanks, all).

But I need more help.

From here on out, until all the prints are gone out of my garage, for every print you buy, I’ll send one to local education. If you simply don’t have any wall space, how about sending the series to a high school near you or your local library? I’ll send another to your local education board.

Get the warm fuzzies, and spread awareness today. For the cost of a few lattes, you’ll be supporting education, your community, and data. Plus, you’ll be getting some beautifully designed prints.

Sunlight Labs, one of my new favorite data groups, has partnered with Google, RedHat, Mozilla, and several others to get the open source community involved in open government projects. They’re calling it the Great American Hackathon and it’s happening December 12-13.

For those unfamiliar with Sunlight, it’s an organization that promotes open government data and transparency, and they fund technology projects (mainly online apps) that move this idea forward.

Organize an Event

If you’re a developer or designer and want to help out, organize an event in your local area for December 12-13, and get as many people involved as you can. The more we make use of open government data, the more people that will see its usefulness, and the more people that care, the more the government will put into data. Get involved now.

The New York Yankees just won the World Series. I don’t know much about baseball, but I do know that Mariano Rivera, the Yankee closer, has a lot to do with the success of his team. Whether you like it or not, Rivera dominates batters with just a 0.74 ERA over 88 post-season games.

The New York Times provides a batter-by-batter look at Rivera’s pitching since 1995. He’s pitched to 501 batters in the post-season. Only 14 runs have been scored off of him.

Are there any differences in student performance between schools with small classes (as in students per teacher) and those with large classes?

The natural response is yeah, of course, because if there are less students per teacher, each student gets more individual attention from the teacher. Then again, I went to pretty big elementary and high schools where some classes were in the high thirties. It didn’t seem all that bad.
