When Profiling Goes Wrong 626
huskymo writes "This morning's Wall Street Journal is carrying a funny story on TiVo and Amazon's automatic customer profiling. As most Slashdot readers probably know, TiVo keeps track of which programs you record and--if you haven't told it not to--records other programs it thinks you'd like. The article describes users that TiVo's mistaken for Korean, for gay, even for "a pregnant gay man.""

Define "does not work." I think profiling often does work, not with 100% accuracy, but it does work. The more data you give it, the better the output you get. Profiling with a very low n is bound to be silly, but as you increase it the results get better.
Profiling is just a statistical correlation (or probably a more complicated type of factor analysis) that says people who like X,Y,Z also tend to like A,B,C. Yes, aberrant data (buying a needlepoint kit for my aunt) can skew the results, but again as the amount of info goes up, the ability of such outlying points to skew decreases. I am more and more impressed with both tivo and amazon's picks as the amount of data it uses increases (even more by tivo, as it is getting a rather split personality input between my picks & my gf's).
point out what people really want is contextual information at the moment
Sometimes. Somtimes people want a list related only to the current action, such as when buying presents. On other occasions, they want a recommendation based on previous likes as well.
Profiling could be used to predict what you want when you ask for it. For example if you are making a query for children's books then the top 10 could be presented. Or a couple of questions could be asked and then a top 10 is presented. But in either case the background of the user is not taken into account.
But why not use the background? Why should I have to repeatedly answer questions to give it information that could be obtained passively?
For different situations, different methods will work better. For things that tend to be more personal (tivo), profiling is great. For things that aren't (gifts from amazon), context would be better. But to say 'profiling doesnt work.' is just wrong. [evidence, look at the ultimate profiling: car insurance...]

A bitmap is a data structure where a collection of bits is stored. This allows for more compact storing of information. For example a 32 bit word can be used to store 32 true-false values. This is more efficient than storing an array of 32 bytes with TRUE or FALSE in them. Bitmaps are not limited to storing true-false data. A 32 bit word can store 8 four bit values as well.
In the pregnant gay man example, the bitmap likley had bits for male/female, gay/straight and pregnant. Set them all to 1's and you get a pregnant homosexual male.
Uninitialized variables are caused when a function accesses a variable before explicitly setting it. This is a common problem in C/C++ and can result in some odd behavior. An uninitialized variable could result in the bits being set even though the program never explicitly set them.

You're not getting my point, Zathrus. I'm talking from a marketing standpoint here, not a personal one. I know perfectly well how to exclude stuff from Amazon (don't have a TiVO), though I haven't been able to figure out how to exclude a whole category that mistakenly includes a handful of books I am interested in - but that's another story.
There are certain topics which any marketing type will tell you are hot-button issues: political party, religious affiliation, sexuality, vi versus emacs. Unlike the last one, you are more likely to offend potential customers if you misidentify their political party, religious affiliation, or sexuality than you are to entice them if you identify them properly (significantly more; you'll maybe offend 3% of the population if you give them a copy of Business at the Speed of Light for Christmas, but you'll offend 60% if you give them a copy of al Quran for Christmas (those whose religious sensibilities are stronger than their curiosity, and those whose religious sensibilities cannot accept the idea of a Christmas gift in the first place)). And given the fact that there are more than two possible political viewpoints (a whole spectrum from Genghisid legalist to utopian anarchist), more than two possible religious affiliations, and more than two possible sexualities (straight/gay/bisexual + male/female), your odds of getting it wrong are greater than 50%. So a sensible marketer would stay clear of those topics.

The suggestion system works by allowing the viewer to press the "Thumbs Up" or "Thumbs Down" button. Strangely enough you can give a show up to three thumbs up or down (most people I know only have two thumbs;). The algorithm uses these ratings to find shows that have been catagorized the same way as shows that the user has rated highly. One thing that most people don't realize is that any show selected for recording automatically gets one thumb up. Naturally, for this system to work, show catagorizations have to be accurate, which isn't always the case.
The users in the article who recorded lots of shows to counter the ratings were doing things the hard way. A much easier way is simply to go to the suggestions screen where TiVo supplies a list of recommended shows that it thinks the viewer might want to see. From there, it's easy to just give three thumbs down to each of the shows that the viewer doesn't like. On a lucky day the show that caused the problem in the first place will appear as a re-run, so the problem can be fixed quickly. This can be repeated until the suggestions screen only shows stuff that the viewer likes.

If your Tivo isn't doing anything else during that time, it will tune itself to Discovery Channel and download all that information.
If you were watching during that time period, you would also see all of the promotional clips, commercials, etc that your Tivo has on its main menu.

To shed a little more light on this, TiVo's suggestions are collaborative; that is, other users' choices figure in to what it records as suggestions for you. That can help explain some of the "inappropriateness" that happens sometimes.

Sorry, but "counter-programming" doesn't work (Score:3, Interesting)
These systems (generically, recommendation systems or collaborative filtering) don't use pre-defined genres or categories. They use correlations between actions to predict future actions. So your recommendations are essentially based on the sum of your past actions. In other words, you can't make it ignore "gay" stuff by selecting "macho" stuff-- it will just sum those together and you'll get both "gay" and "macho" stuff.
Worse, if enough people try to outsmart the system, it pollutes the correlations. "Gay" and "macho" items become linked together, and requesting one makes it recommend the other. This can work both ways. If most of the people who record "The Rise and Fall of the Third Reich" are doing so to counter their watching "Queer as Folk", then someone who watches "Third Reich" will get "Queer" as their first recommendation!
In case it's not clear how this works, let me describe one generic type of recommendation system. The system forms rules like "People who like A also like B, C, and D" based on analyzing its database, with some definition of "like." This being e-commerce, it's usually "like=buy". It might be more complicated, e.g. "35% of people who buy A also buy B."
These rules can be shown raw, as Amazon does, or they can be personalized. I've bought A, C, and D, so it combines the rules for A, C and D (using set intersections, sums, averages, etc. depending on how the rules are stored.) It decides, in essence "People who like A like B; people who like C like B; you like A and C, so you probably would like B."
So if you wanted to counter your watching "Queer as Folk", what you would want to do is not train it with "anti-gay" input, rather you would want to flood it with "everything but gay" input-- BUT you would probably have to do it IN EQUAL PROPORTION to the viewing habits of the average person in their database.

Re:Thumbs Up/Down Buttons (Score:5, Informative)
It is not a good idea to give three thumbs-down on a lot of shows, this will tend to deterioriate the suggestions algorithm. One thumb is usually sufficient, but keep in mind that TiVo doesn't know, for an individual show rating, WHY you thumbed it, so it adds or subtracts weighting from entries for genre, actors, directors, etc.
As an example - my wife has season passes for various home improvement shows, such as Changing Rooms. So we get lots of suggestions for other home and garden shows, including various Martha Stewart shows. My wife hates Martha, so we give her shows one thumb down, but the TiVo doesn't know it's because of Martha. It's the collective weight of other ratings that tune the suggestions.
For a while, there was a hidden feature called TeachTiVo, that allowed you to rate individual actors, directors, titles and genres. The UI wasn't complete (and was buggy), and you had to "enable backdoors" to get at it at all. The whole feature was removed in recent versions, unfortunately. I'd like to see something like it return in the future.

On Amazon.com, Too; Why the Cartoons?

Basil Iwanyk is not a neo-Nazi. Lukas Karlsson isn't a shadowy stalker. David S. Cohen is not Korean.
But all of them live with a machine that seems intent on giving them such labels. It's their TiVo, the digital videorecorder that records some programs it just assumes its owner will like, based on shows the viewer has chosen to record. A phone call the machine makes to TiVo, Inc., in San Jose, Calif., once a day provides key information. As these men learned, when TiVo thinks it has you pegged, there's just one way to change its "mind": outfox it.
Mr. Iwanyk, 32 years old, first suspected that his TiVo thought he was gay, since it inexplicably kept recording programs with gay themes. A film studio executive in Los Angeles and the self-described "straightest guy on earth," he tried to tame TiVo's gay fixation by recording war movies and other "guy stuff."
"The problem was, I overcompensated," he says. "It started giving me documentaries on Joseph Goebbels and Adolf Eichmann. It stopped thinking I was gay and decided I was a crazy guy reminiscing about the Third Reich."
He mentioned his TiVo tussle to a friend, who told an executive at CBS's "The King of Queens," who then wrote an episode with a My-TiVo-thinks-I'm-gay subplot.
A lot of gadgets and Web sites now feature "personalization technologies" that profile consumers by tracking what they watch, listen to or buy. The software, embedded in sites such as Amazon.com and CDNOW.com, then recommends other books, videos and music based on a customer's tastes.
The Willies
Many consumers appreciate having computers delve into their hearts and heads. But some say it gives them the willies, because the machines either know them too well or make cocksure assumptions about them that are way off base. That's why even TiVo lovers are tempted to hoodwink it -- a phenomenon that was also spoofed this year on another TV show, HBO's "The Mind of the Married Man."
Mike Binder, creator and star of that show, had set his home TiVo to record his 1999 movie, "The Sex Monster," about a man whose wife becomes bisexual. After that, Mr. Binder's TiVo assumed he would enjoy a steady stream of gay programming. Unnerved, he counteracted the onslaught by recording the Playboy Channel and MTV's spring break bikini coverage. It worked, he says. "My TiVo doesn't look at me funny anymore."
His wife, however, was taken aback when she saw all the half-naked women he was ordering through TiVo. He told her those women meant nothing to him: "I'm just counterprogramming because TiVo thinks I'm gay." She was unamused. The incident inspired an episode of his show.
Though some users contend TiVo has sex on the brain, TiVo's general manager, Brodie Keast, explains that the box is merely "reacting to feedback you give it." Still, the machine employs algorithms -- searching several thousand key details (favorite actors, movie and TV genres) -- that leave some people wondering whether it is judging their predilections.
Mr. Karlsson, 26, says he "pre-emptively" found all the religious shows in his TV listings and used the "thumbs down" button on his remote control to tell TiVo he has no interest in them. (Giving three thumbs down is the best way to block a program.) After that, his TiVo recorded movies about creepy homicides. "They all have titles like 'Murder on Skeleton Isle,' " says the computer system administrator in Cambridge, Mass.
He uses the "thumbs" button to tell TiVo he hates such films. He also orders cooking shows, which softens TiVo's view of him. "I don't want it thinking I'm an ax murderer," he says.
Mr. Cohen, 30, has a TiVo that mysteriously assumed he wanted Korean news programs. The Philadelphia lawyer gave thumbs down to anything Korean, and his TiVo got the message. Sort of. "The next day, it recorded the Chinese news," he says.
TiVo's 500,000 subscribers use the box primarily to record programs they specifically request, and many laud its ability to pause live broadcasts and record a show's entire season. Still, in TiVo-focused online chat-rooms and in secretive admissions to one another, some say they resent being pigeonholed by TiVo's suggestions.
'A Pregnant Gay Man'
Like TiVo, other techno-profilers run hard with limited information. Ray Everett-Church of Fremont, Calif., who is gay, ordered "Queer as Folk" videos from Amazon.com. Understandably, the site began suggesting gay-related calendars and books. Then he bought a baby book for a pregnant friend. So for weeks, the site also recommended parenting books. He says it was as if Amazon.com decided he was "a pregnant gay man."
He fought back, he says, "by inundating it with additional data. I searched for other stuff -- on politics, computers -- so it would stop throwing baby books at me. Now it thinks I've abandoned the baby and I'm preparing for a career in politics."
Mr. Everett-Church, a privacy consultant for businesses, predicts that as techno-profiling increases, more people will purposely muck up their profiles. They'll fear ordering books on mental illnesses or sexual preferences because they'll wonder if they'll somehow be publicly identified.
All techno-profiling companies contacted for this article said that information gleaned is for the customer's personal use only. Still, even Amazon.com founder Jeff Bezos knows the potential mortification factor.
For a live demonstration before an audience of 500 people, Mr. Bezos once logged onto Amazon.com (amazon.com) to show how it caters to his interests. The top recommendation it gave him? The DVD for "Slave Girls From Beyond Infinity." That popped up because he had previously ordered "Barbarella," starring Jane Fonda, a spokesman explains.
Dawn Freeman, 23, a tax analyst in Lexington, Ky., has bought lowbrow videos, such as "American Pie," from Amazon.com. But she was aghast when the site suggested Tom Green's gross-out performance in "Road Trip."
"I thought, 'I know I don't like high cinema, but have I really reached the point where I'd like to watch Tom Green lick a mouse?" To even out her Amazon profile, she went through the site finding "witty independent films."
Her TiVo also thinks she's a sophomoric-humor-loving 12-year-old, she says. It keeps giving her cartoons. "I know it's dumb to take it personally, but it's in your face. These are supposedly objective computers saying, 'This is what we think of you.' "
Dissing Ice Cube
A.J. Meyer, a 35-year-old Web site developer in Minneapolis, ordered the DVD for "Scarface," the Al Pacino gangster movie, from Netflix.com (netflix.com). After that, the site kept recommending movies about gangster rappers. He stopped the assault by giving negative ratings to all movies starring Ice Cube. (Netflix allows members to rate any of its 12,000-plus titles with one to five stars -- whether they have rented a film or not. That helps the site calculate future recommendations.)
After Mr. Meyer ordered a documentary about New York from Amazon.com, it pitched him countless documentaries -- even one on the history of the thimble. He stopped the Ken Burnsification of his profile by searching the site for plasma TVs. "That way, I identified myself as a high-tech guy," he says. "The thimble is more low tech."
Virginia Heffernan, TV columnist for Slate.com, doesn't understand why some people are resistant to techno-profiling, or find it creepy. She didn't look for any deep meaning when her TiVo kept giving her TV shows in Polish. And after buying self-help books on Amazon.com, she accepted that every time she logged on, the site pitched products to make her a more self-fulfilled human being.
"I like the idea that someone cares," she says. "Even a machine."
TiVo users can program the machine to skip certain channels entirely. But many users don't bother to figure out how to do it, or are too intrigued by TiVo's recommendation process, says a spokesman. TiVo is paid to promote programs and products it calls "advertainment" on a special screen. But the company says none of these are given to users as suggestions.
Some people have given up trying to manipulate personalization technologies. Dino Leon, a hair-salon owner in Birmingham, Mich., says his TiVo quickly figured out that he and his partner were gay. They were OK with that, but just for fun, they tried to confuse the software by punching in "redneck" programs, like Jerry Springer's talk show.
TiVo wasn't fooled, and kept recording gay shows. Mr. Leon believes the box was giving them a message: "You're definitely gay. And you're watching too much TV."

Fair use considers how much of the text is used, and using the whole thing all at once is almost certainly to be found a violation by the judge.
Additionally, fair use considers "monetary damages" caused by the use. Since the Post has a subscription system and not just the standard advertisements, "monetary damages" could be very significant; people who might have subscribed instead just read it here.
IANAL either but most people extremely seriously overestimate the power of fair use. Posting the article was a copyright violation, to a high enough degree of certainty I don't feel the need to qualify that with any variation of "probably".
Remember... the law is not what you think it is, it is what the the law says and how a judge interprets it. The Slashdot community as a whole is very incorrect in its interpretation of "fair use".

Find the 700 Club in the listings and give it 3 thumbs-down, or if TiVo is suggesting it, give the suggestion 3 thumbs-down before deleting it.
Alternatively, drop the entire channel it airs on from the list of channels you receive. The whole channel's run by Pat Robertson anyway.

That's not quite how it works, and you can turn it off anyway.
Suggestions are only recorded if there is space not currently used by things you asked for. They will never overwrite something you explicitly recorded; only free space or other suggestions.
There is also a switch to turn suggestion recording off.
(Leaving it on is actually useful, because there's no other way to tell how much space you have available; that way, when your suggestion list starts to shrink, you know you're running out of space and it soon will be deleting stuff you asked for.

There aren't hundreds of posts bashing TiVo for profiling. Oh wait, that's because people can't even pretend to read the article because it requires a SUBSCRIPTION! heh.
Thing is, we're dealing with two separate issues here.. The "profiling" Tivo does is periodically it phones in stats on everything you recorded and/or watched, which Tivo (the company) compiles and sells as anonymous viewer data to the networks (i.e. 5,000 of our subscribers recorded Dawson's creek this week, of those 4,000 watched it within 48 hours, and 1,000 deleted it after watching the first 10 minutes").
The second issue is Tivo's suggestions.. *As far as I know* (and I could totally be wrong here), your Tivo computes suggestions on the box itself, not by consulting with some master Tivo database somewhere. It's really quite braindead... All shows are assigned categories, so Tivo computes a "probability" of whether you may or may not like a given category based on your thumb-data. For example, if you thumb up the Simpsons (category Animation, Comedy), you're likely to see stuff like Futurama, and lots of stuff on the cartoon network which fit those categories. Some lines are a little blurry, I thumbed-up Politically Incorrect (when it was on the air) which was categorized as News, Talk, and got crap like the O'Reilley factor, CNN's crossfire, etc. Some things are a lot easier, I thumbed up a couple of motorcycle races, and from then on it would catch motorcycle races I didn't even realize were being broadcast.
Contrary to the anecdotal evidence in the article, in my experience approving one category will NOT lower your "approval" of another. I think only thumbs-down will do that (i.e. thumbing up Emeril Live - Howto, Cooking - shouldn't dimish its afinity for Movies, Horror if you have thumbed up Texas Chainsaw Massacre).
My theory I have after owning a couple of Tivos is at first when you haven't rated much it tries to throw a wide variety of EVERYTHING at you to get you to rate stuff and get it pointed in the right direction. During the first three months I got some strange suggestions (my Tivo thought I was a kid for a while, and recorded just about everything on HBO Family, presumably because of my favorable ratings for simpsons, futurama, king of the hill, and family guy. But I have to say after three months it got REALLY good and finding stuff I'd want to see.
There has been talk that in future releases some of the suggestion tweaking will be done on the in-house Tivo servers and pushed out to the boxes (i.e. people who record MST3K on commedy central also record Monty Python on BBCA most of the time). But to my knowledge right now all of your suggestions happen in the Tivo box itself based on input from you, and are not neccessarily shared back to Tivo corporate or influenced from the suggestions of other subscribers.
