Facebook's Face Identification Project Is Accurate 97.25% of the Time
kc123 tips news that 'DeepFace,' the software research project created by Facebook engineers to identify people in pictures, is now accurate 97.25% of the time. In other words, it's almost as good at recognizing faces as humans, who are able to determine whether two photos show the same person 97.53% of the time. The article says DeepFace reaches that level of accuracy "regardless of variations in lighting or whether the person in the picture is directly facing the camera." It continues,
"DeepFace processes images of faces in two steps. First it corrects the angle of a face so that the person in the picture faces forward, using a 3-D model of an 'average' forward-looking face. Then the deep learning comes in as a simulated neural network works out a numerical description of the reoriented face. If DeepFace comes up with similar enough descriptions from two different images, it decides they must show the same face. ... The deep-learning part of DeepFace consists of nine layers of simple simulated neurons, with more than 120 million connections between them. To train that network, Facebook’s researchers tapped a tiny slice of data from their company’s hoard of user images—four million photos of faces belonging to almost 4,000 people."
To more of your privacy in the commercial world.
"You've just been DeepFaced" But at least its all for a good cause, marketing and profits at the cost of our private lives!......
It sounds like the next capital hill scandal. Fortunately for teenaged girls, their faces are always scrunched up and lips pursed, when they turn 25 and take a normal picture Facebook won't be able to recognize them.
Remember, Charlie Chaplin once lost at a Charlie Chaplin look alike contest.
So did Harpo Marx.
(He didn't look a thing like Charlie Chaplin.)
Please notice that this feature can be disabled in you Facebook account options. I'm at work and can't access it right now but I know the option is there, which takes care of both auto tagging (i.e. DeepFace) and manual tagging (i.e. your friends tag you on photos).
And It's not like your Facebook ID was issued when you were born, like your SSN or birth certificate. You willingly signed up for the service, so quit complaining about privacy bullshit, or quit using Facebook.
All it takes is to be identified once. Just one friend snapping a picture of you & pals at a wedding,who then posts the picture on FB, and dutifully identifies each person in the photo. After that, every image of you available on the web will be linked to you. That picture of you puking your guts out at some drunken frathouse blowout that you hoped everyone had forgotten about will now be on the first page of a Google search on your name.
If construction was anything like programming, an incorrectly fitted lock would bring down the entire building...
Fuck Facebook
So, you're saying that "Deep Face" is a euphemism?
...because they all look alike? I heard they were all really smart and know martial arts, too.
4 million photos of 4 thousand people. That is an average of 1000 images of each person. Wow. It's really hard to imagine people have that many photos of themselves on Facebook (okay, the teenagers do take selfies daily, but that would still be 3 years of daily selfies). I also see a lot of occurrences of people being "tagged" in a photo just so that person will be alerted to the existence of the photo - for example, photos of their kids doing something cute. That's gotta fuck with the algorithm a bit.
I logged into Facebook for the first time in about 6 months, and it required me to authenticate myself by answering a series of questions about who was in each picture. It would display 3 pictures, each showing a square around a particular person, and it would ask who the person is. It was multiple choice.
I wonder if this is how they confirm that the data is correct, to eliminate intentional errors. You can ask a person who doesn't own the picture and didn't tag it to confirm the person in there. By masking it as an authorization request you convince people who otherwise would not be involved in tagging to participate.
Recently, FB decided that it needed to verify that I was really me when logging in. To do this, it presented me with a bunch of photos from my "friends" that had been tagged and insisted that I choose a name of someone in the photo. If I got enough of them wrong, it would "lock" my account. (Not quite "lock" but I had to try it again). Not only did it pull up obscure photos from "friends" I rarely interact with so I had little chance of knowing who was in the photo. But get this: It pulled up photos of people facing away from the camera and expected me to know who the person was from behind. Da fuq, FB? Seriously?!?
