It's easy for humans to identify faces in pictures on Facebook, but the method isn't as simple for computers. Sure, Facebook has a suggested prompt that predicts who you're trying to tag, but now the company is working on a technology that promises "near-human accuracy" so you won't have to do it yourself in the future.

Facebook's API Group is developing software called DeepFace, which maps 3D facial features and creates a colorless model to narrow in on specific characterizations. The accuracy of the method is 97.25%, which is just under the 97.5% accuracy that a human can identify, according to the group.

 Facebook:-  "We present a system (DeepFace) that has closed the majority of the remaining gap in the most popular benchmark in unconstrained face recognition, and is now at the brink of human level accuracy," researchers said in a report released by Facebook API Group. "It is trained on a large dataset of faces acquired from a population vastly different than the one used to construct the evaluation benchmarks, and it is able to outperform existing systems with only very minimal adaption."

To develop the technology, Facebook looked at 4.4 million tagged faces from 4,030 of its users to help the system learn how to better identify features specific to each person. The report also reveals that Facebook looks at modern face recognition in four phases: detect, align, represent and classify.

"We revisit both the alignment step and the representation step by employing explicit 3D face modeling in order to apply a piecewise affine transformation, and derive a face representation from a nine-layer deep neural network," the company notes on its DeepFace page.

This deep network involves more than 120 million parameters using several locally connected layers without weight sharing, rather than the standard convolutional layers. Thus we trained it on the largest facial dataset to-date, an identity labeled dataset of four million facial images belonging to more than 4,000 identities, where each identity has an average of over a thousand samples.

Although we might not see the updated approach on Facebook just yet, the site is expected to present it at the IEEE Conference on Computer Vision and Pattern Recognition in June, according to MIT Technology Review.

Secret behind success of mashable

Mashable has been a remarkable success story in blogging. Pete Cashmore started it when he was 19. He started it in his bedroom in Scotland where he is from. By now it gets more page hits then the top tech blog TechCrunch. That has been true for months. Mashable has a more well defined niche than TechCrunch, and it is more focused on the user.

Switching from being a one person blog to a team blog must have been a major milestone for Mashable. The fact that Mashable has no plans to be sold - "Everyone has a price, but ours is a really high" - should tell you the blog has serious plans to keep digging in its niche. Getting sold to a bigger name company might only blunt that one edge the blog has, that it is your ultimate social media guide. Why not just keep building the traffic, and keep adding to the content, and keep charging more for the ads, right?

The Facebook founder was also 19 when he launched Facebook.

Facebook And Mashable: Social Media And Social Media Blog
2010 Trends: Pete Cashmore's Take

TechCrunch Vs. Mashable: There's No Competition Mashable is more about internet culture than pure tech news these days..... if there's a hot celebrity story trending on Twitter they'll find a way of covering it to reap the search engine traffic, if there's a viral video doing well they'll embed it to get the retweets.
AOL In Talks To Acquire Mashable -- Reports AOL is trying to transition from an ISP to a next-generation media company. .... It already has 80 or so independently branded blogs and is planning to grow to more than 100.
The Man Behind Mashable He's been crowned the king of Twitter and is one of the most influential figures in the technology industry. ..... Since setting up Mashable in 2005, while working as a web technology consultant, Cashmore has divided his time between his home town of Aberdeen and the bright lights of Silicon Valley. He's been in Scotland since October, and won't return to the US until January, relying on his team of 15 full-time bloggers and 50 regular contributors to help him keep on top of the key stories.
Mashable’s Identity Crisis They’ve reached that point of critical mass that most bloggers only dream of. The last I heard they had suprassed 20 million page views a month ...... a few months ago Mashable made BIG NEWS by announcing they were going to be hiring real, actual journalists .... some kind of direction shift for Mashable and that they were now interested in serious reportage and investigative journalism ....... s sensationalist and often pedantic blogging ..... Right now it is on track to be the People Magazine of social media. ..... they are interested more in acting like a tabloid.
So What Do You Do, Pete Cashmore, Mashable Founder and CEO? not yet 25. ..... Founding the site was pretty much his first job, as he worked as a Web consultant for a short time beforehand. The site's mission is to be "the social media guide" and cover all things social media. ...... starting Mashable in 2006 from his bedroom in Scotland. He was 19 at the time. ....... I just was really passionate about the space, and wanted to get involved, and I felt like social networking wasn't being covered to the degree it could be. ....... It was personal interest. I didn't necessarily know there was an audience for it. ...... In 2006, we did our first ad deal. It was only a few thousand per month, but it kind of legitimized blogging as a business. Selling a first ad legitimized that this may go somewhere -- this may actually work. ....... When you compare [Mashable] to old school tech magazines, we certainly say we're more focused on the user and the utility for users. For example, we don't cover things like funding announcements. We focus on the user. ...... there is value in both original reporting and curation ...... They're going to cover what they're going to cover. It's up to them. ...... There is no point in writing like the pyramid anymore. You have to write the story in three paragraphs. ..... They need to become both sources of news and curators of community-sourced news. ..... Content is not a scarce resource; attention is a scarce resource. If you put [up] barriers, they will go elsewhere. In the vast majority of cases, a pay wall is a hindrance. We should be focusing on how we [can] make ad models that are more engaging rather than push readers to other sites. ....... We're in a niche where we feel we're leading.
