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.
Facebook is, among many other things, the top photo sharing service on the web. And face recognition plays a very important role in this aspect. They must invest a lot in this kind of technologies, so it's no surprise skynet will be born from them.
This news was showing in a lot of sites lately, couldn't wait to see what discussions it would spark here! Let me grab my popcorn!

Fuck Facebook
Humans, despite having a lot of specialized hardware for it, suck at it under many conditions.
Remember, Charlie Chaplin once lost at a Charlie Chaplin look alike contest.
Let us not forget how good Reddit was at identifying the Boston Bombers.
Which is why there is not a single photo of me online that is linked to my name. So even though I may well be in a few tourist shots they can't find out who the ugly looking guy in the background is.
Yet.
However I suppose its only a matter of time before [select government here] matches up driving licence/passport photos using this tech against any street scene photos it can find on the internet and give a rundown of places you've been and possibly when. If they haven't done so already.
Or at least I hope so. I've been falsely tagging myself in Facebook, reversing and randomizing the tags, for years. I wish more people would poison the well instead of trying to go "invisible", we just need about 1/3 errors to discredit positive ID as a method.

Our privacy has been gone for a long, long time.
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.

I haven't had a Facebook account in three years. Wonder if any of my photos lingering around will have any effect on me.

Etc.
Facebook are now effectively doing an even greater amount of significant surveillance work for the U.S gov, seeing as how they are required by "law" to hand over all data. There will be a Facebook Protection Act, just like there was for Monsanto, because they are both essential to the expansion of U.S politics and control. Luckily you can still opt out.
I read the paper and while the approach of learning a representation for faces, and then classifying in that new space whether the face is the same as model is sound, the representation is trained on a closed dataset (the 4m faces from facebook).
So it means that there is no way for the scientific community to check whether the results are correct or not. The results in the paper lack a comparison to a reproducible result, like using the youtube or faces in the wild datasets to train the representation, and then report results given that representation. This way researchers could validate the approach.
I would never have accepted such paper if I were to review it.
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.
Seems quite a technical achievement, but more importantly is the false positive rate.
Start wearing masks and disguises when out in public.
Plus if you use a gas mask that will cut down on the pollution and allergens.

A better approach is for everyone to wear Groucho Marx masks, that makes everybody look the same.

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.
The large corps are doing just fine, but I probably won't be able to use tech to recognize people because GLASSHOLE.
This is a sad world.

How can they recognize you by your FB picture, when half the people use pics of their children or cats?
Slow down, cowboy! It has been 4 hours since you last posted. You must wait another few hours.
Excellent. When can I use this technology to identify and recruit my evil twin for nefariously comedic purposes?

Why anyone trusts this corrupt company with the details of their life is a complete mystery.
How could it possibly be more obvious what they really are?
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?!?
So if there are 1.3 billion Facebook users with an average of 1000 photos each, thats 1.3 trillion photos, of which Facebook will incorrectly identify over 35 billion.
That doesn't sound so good does it?
Well I don't know about everyone else but the state already has my picture and address on my drivers license. Add the information on my tax returns and the state really doesn't need to do anything else if they want to find me. Both of these sources of information were available well before the Internet ever existed.
"four million photos of faces belonging to almost 4,000 people" - So they need 1000 pictures per person to be able to get to 97.25%?
so you've never had a passport or driver's license?
Thank you Dave Raggett
I think it's to hit the 97.53% number they have for humans...basically its PR...internal & external PR
Internally, that DeepFace team has to justify their existence
Externally, f/b uses these headlines to drive their ad revenue
It's all a shell game, from a researchers perspective. It's essentially psuedo-science....it's engineering demonstrating a capability not data proving/disproving a hypothesis that is being actively tested.
Thank you Dave Raggett
Yeah, but what if the State wanted to know where you were a week from last Tuesday, or wanted to look for leverage over you based on your purchasing habits or travel habits? Now it's a bit less innocent.
Today's Sesame Street was brought to you by the number e.
That way when I'm sitting across from some asshole on a train, I can know his name, age, marital status, whether or not he has children, what his daughter's political views are, what his political views are, etc. instantly rather than having to guess. I hate having to guess.
Course I need to get Glass too. Does it have games? I think my favorite game would be one called “NSA says”. NSA says, “Look for this guy [face pictured].”
Yay, I found him. 5 points!
Later:
What was that popping noise? Hey, he fell down. That must have been it. Bubble wrap probably.
privacy is a human right and if you don't believe that, just wait.
Is that that new feature that allows me to stick my cock down facebook's throat?
Slashdot users already promote their privacy via face and neck beards and have been for years.

"Up Your Face" Or something like that...
Exactly why would the government need leverage over me? That assumes the government wants force me to do something against my will but I cannot think of a single thing that would make this happen. My purchasing and travel habits get logged every time I use a credit or debit card. Just like all my phone calls get logged so the phone company can bill me. My cars are registered with the state and county along with my insurance details. Property that I own is registered in county records for tax assessments and if I was married my marriage license would be logged. My freaking dogs have county rabies inoculation licenses stored in the county database. These are all ordinary pieces of information that have been collected and stored way before the computer age. It just took longer to obtain process this type of information without computers. I think people are having a hard time understanding the difference between privacy and anonymity. All of the domestic data supposedly collected by the NSA was already being captured and stored by others. The question is whether it is legal for the phone companies or web sites to hand over call logs and other information without first obtaining a warrant. Google and other mainstream sites capture every click you make and packages up the results to sell to 3rd parties to generate revenue while also utilizing your browsing habits to "customize" the ads you see on your screen.
Gosh, what if your face is recognized in public? And people find out you shop at Walmart. OMG.
So much for leading a life of crime.
