How Machine Learning Can Transform Online Dating
First time accepted submitter hrb1979 writes "Thought I'd share an interview with Kang Zhao — the professor behind the machine learning algorithm which could transform online dating. His algorithm takes into account both a user's tastes (in an approach similar to the Netflix recommendation engine) and their attractiveness (by analyzing how many responses they get) — enabling the machine to 'learn' and hence propose higher potential matches. His research was recently covered in both a Forbes' article and the MIT Technology Review, though this interview provides more depth and color."
gnu online dating failed decades ago? who can forget the embarrassing AD campaigns like we were all ADDing in
All the algorithms in the world aren't going to help when the intersection of "people you'd care to date" and "people who'd care to date you" is empty. What we need is an algorithm to convince people to lower their expectations when they're unattractive, boring, unmannerly, old, poor and/or cheap, have baggage, etc.
His research was recently covered in both a Forbes' article and the MIT Technology Review
It was also recently covered on Slasdot.
This doesn't take into account chemistry, which is where feeling love comes from. If you want the logical mate, then sure you can probably create something like this. If you want a real match, you'll also need to send in hormones and blood samples for testing. It would probably also help if people didn't lie so much online.
Garbage In Garbage Out.
Who writes honest truth in the online dating profile? It is all about posturing and posing.
remember; submit the script that embeds a virtually invisible (or not) camera/mic. combo into the rendered web page of the suspected hobbyist whiner. prizes are that we are all our own reward free as in good spirits. free the innocent stem cells is not avoidable. never a better time to consider ourselves in relation to momkind our spiritual centerpeace & new clear option provider at healthcare.love. like spirit bugs we do not always see them......
Somehow I get the feeling that I won't have any success with this. I'm a typical Slashdot user.
If the algorhythm is based on "attractiveness" won't that lead to the beautiful only being paired with their like? Will uglies only be paired together? Could he have chosen a worse metric to use? I think not. Bad idea on so many levels.
I bet "loves to travel" and "loves having fun" have zero predictive power.
This is where evolution backfired. It used to be the case that physical characteristics highly correlated with reproductive success, so we are hard-wired to look for them. Sometimes this takes strange detours into fetishes-obsessions, but most of the time we just looking for "good looking".

Males: Enter income.
Females: Enter attractiveness.
Match up most attractive to highest earners.

Tired of getting messaged exclusively by single moms and financially/emotionally unstable ladies on OKStupid.
Kind of like job interviews. It's not that hard, really: if they don't like you after you're in the door, you've still gotten out of your mom's basement for a day and had a chance to steal some pens. It also gets you a chance to talk to the people who actually *work* at the company, who know what department actually needs your real job skills. Same with "si8ngles" dating. Even if the "single" is a real brown bagger, she may have friends who are interesting to meet and will "rescue" their friend by distracting you.
Nothing gets them wanting to go out like seeing that their friend is out with you. Think I'm kidding? Just watch them at a good party.
This is true even though a homely spouse makes for a much more attentive husband/wife.
Do they? Ugly people are just as capable of obnoxious behaviour as attractive ones.

Being recently divorced (last year), I started poking around at the various dating sites. Let's see, I don't smoke, I effectively don't drink alcohol (one beer a year doesn't make me a "drinker"), I'm a gamer (you'd be amazed at the number of women who think gamers are "childish"), and I'm not into sports (lots of women who go to football/baseball/hockey games). I do like going hiking in the mountains, snowshoes, skiing, I like bicycling. But I'm not a fitness fanatic which also eliminated quite a few women. I'm not religious which eliminated a few more.
After eliminating the mis-matches, I started paring down the other issues. Based on profiles, I got down to about 60 women in the area who might be an match based on shared interests. I received no replies to my e-mails but I did receive three unrelated emails. One from a women in Australia. One from a woman in Texas who had pictures of her daughter leaning on a car (which was a bit creepy). And one from a woman who plays guitars who appeared to be looking for a man in every city.
Amusingly on my birthday (hit 56), my match list dropped to zero. Every one of the women were looking for guys 55 or younger. So I expanded my search until I got to a couple of women in a 250 mile radius.
For some of us (a small percentage I suppose), the dating sites really aren't helping. And since women receive all the emails, they have the choice of who to go out with.
Humorously I was chosen to moderate pictures on okcupid for a bit. The guys do send some very suggestive emails (and some not so suggestive!).

Ask them *all* out. Last I checked, Richard M. Stallman was still using the "try them all, and any that work, whoopee" method. My trans-sexual friend considered it her trial by fire when Richard Stallman hit on her. And brother, if it works for *Richard*, it can work for anybody!!!!
Mind you, I observed him doing this from 1981-2001. He may have shifted tactics in the last decade.....
The problem with online dating from a woman's perspective doesn't seem to be in finding matches, it is in trying to develop a relationship in the face of all the other potential matches that are one-click away for the man. A better matching algorithm will not help with this.
The perfect formula for matchmaking: Men just have to say, "I want to have kids" to be flooded with responses.
I think there is some truth to this. I seldom see drop-dead gorgeous female engineers or scientists. On the other hand, female cheerleaders make me cringe and despair. You don't think there is a strong correlation between attractiveness and personal qualities/careers/etc.?
Women: Are you attractive?
Men: Are you rich?
"I don't believe that a computer matched you up..."
While I think you are saying some truth, I don't think it's the whole story. Being interesting, attractive or hot are always subjective measurements. If your high school's cheerleaders don't find you attractive does not mean you are not attractive. Why does their opinion worth more than what the rest of girls may think?
Most of the time it just turns out that we are trying to intersect with sets of people who are unlikely to find us interesting. If I hate sport, it just doesn't make sense to go to a website which links sports fans. If I hate fashion, I should not try to hit on girls spending 6 hours a day reading the latest trends. But that doesn't make me unattractive or boring. To me, those sports fans or fashion girls are boring and unattractive too, but there certainly are people who will find them exciting and interesting. It's all a matter of perspective.
In the end, I think all boils down to two things: attitude and luck. Be positive, and sooner or later, you'll be in the right place at the right moment.

Let us say that intelligence and attractiveness are uncorrelated.
The probability of being both at once is very low, since you're multiplying the two small independent probabilities associated with attractiveness and intelligence.
If, of course you chose any segment of the population not selected specifically for attractiveness, then the probability of any given member being attractive is low.
Drop-dead gorgeous female scientists and engineers are particularly rare because (a) female scientists and enigneers are rare and (b) drop-dead gorgeousness is rare. Even uncorrelated if you multiply those tow probabilities, a small number results.
If you have something where members are chosen for attractiveness then yes, the average member will be more attractive than the average.
Would I say that my fellow scientists and engineers are on average less attractive than a random sampling of the population? That's a hard call. There are whole segments of the population that I rarely mix with which makes such things hard to judge. I never have cause to visit grim, deprived, crime ridden former mining towns of the North for example. But I haven't noticed any particular difference. There's one guy in my office you could easily tell from the outside (long hair, overweight and wearing anime t-shirts is kind of a give away). The rest not so much.

So, in other words, the machine will tell you, "Hey dude, you might as well talk to this homely girl, because we've analyzed your interests and your apparent attractiveness and you're not going to do any better than this".

I seldom see drop-dead gorgeous female engineers or scientists.
That's because smart and gorgeous women know that those professions are underpaid and undervalued in Western (particularly American) society, so they avoid them (they also want to avoid all the sexual harassment). Instead, these women go into the medical field. I've met several nearly drop-dead gorgeous female physicians. And they certainly get better pay and better job security than I do as an engineer, while not being surrounded by creepy men or brogrammers.

Ugly people are just as capable of obnoxious behaviour as attractive ones
True statement. But attractive people (especially women with large breasts) tend to be conditioned by society to think that they are more desirable and hence that they are entitled to be more demanding. Same with guys who are good athletes or have lots of money.

I'm guessing that Search Engine Optimization (SEO) techniques would come into play whereby geeks could artificially inflate their relevance/attractiveness to game the system. Once again the nerds get the supermodels... right?
Does input data to this so-called transformational algorithm come from online dating sites? If so, it's self-selecting from a questionable population, since these are people who have trouble with regular dating in the first place. Would there be much statistical difference between this transformational algorithm and matching up pairs from this population totally at random? What's the control group that determines that this algorithm is better (or worse)?
I don't care about dating, but I care about the bogus statistics.
I'm in my 40's and married, but back when I tried seriously using a few of the dating sites (never was willing to pay for the commercial ones, but gave sites like PoF and OKCupid a shot) -- I ran across a general theme for the individual who'd find the most success there. Basically, the formula seemed to be:
1. Into sports
2. Posted at least one sexy/arousing type photo instead of only head-shots
3. Somewhere in the "under 35" age range
4. Liked to "go out for a few beers/drinks" (but not "drink heavily", of course)
5. Claimed to have some type of job people perceived as "successful"
6. Those under 25 who bragged about "420 friendliness" (marijuana) seemed to do well with others in that age range.
Older people definitely tend to be the "outliers" on these sites -- with relatively few peers using them for dating. Worse yet, I think some of the 50 and 60 somethings use them to troll for much younger dates, sometimes even lying about their age to get the first in-person meetup.
I tried to be pretty honest about exactly what my interests were (and weren't), but found that didn't get me many initial contacts. I think just as in "real life", there's still sort of an expectation that the man is supposed to make the first move. Women will put a profile out there and just let the emails rolls in. Men put one out there and it gets viewed a number of times, but winds up only serving the purpose of getting reviewed closely if he contacts a woman first and she's trying to decide if she wants to write him back or not.
I'll tell you another thing that might be worth doing, if you want a "reality check" about your level of physical attractiveness to the opposite sex. Find a couple of photos of yourself you feel represent you well/accurately and post them on one of those "Hot or Not?" sites. Come back a few weeks later and see what your average rating was. I did this once, and frankly, it was pretty brutal. I wound up ranked about a 3 out of 10 -- despite being a guy I'm somewhat regularly told is "fairly attractive". I tried to analyze it, and discovered a few things -- like much younger women rating me really low, simply because I was "too old for them". But at the end of the day, I think it's important to realize that a lot of people using these dating sites will be clicking through guys' photos and profiles with this same mindset. "Ick... he's wearing an ugly shirt! Next!" "Looks like he could be my dad or something. Ugly! Next!" So without letting it shred your ego, I think it does provide some perspective at least -- when you get mad that "There are 1,000 women on this site right now and not ONE wants to write me back!?!"
And if they can't accurately predict you what movies you will like or dislike, there's no way they'd be able to predict you who you'd date or not.

I'm always surprised when I run into the contrary examples of women dating men who are by most measures less attractive than they are.
The two examples that come to the top of my head are both good friends of my wife and I.
One woman is in top physical shape (runs like 25 miles a week), high end corporate job (director of a hospital) and her husband is an easy 75 pounds overweight and some kind of rank-and-file finance guy. In three major respects, looks, earnings, and "job status" he's at a lower level than she is, yet they get along great.
The other one is less of a mismatch in terms of jobs (he's a realtor, she works as an assistant to him on real estate), but she is very, very attractive -- very pretty. Without being too crude, a really amazing figure in all respects, even more so amazing in terms of the fact she's 40+ with two kids. Her husband is paunchy and not nearly as good looking as she is.
This happens often enough that I figure that simple "looks" is far less important to women than it is to men, and that many women are either willing to overlook some aspects of appearance or simply don't care.

Well, there is some truth to what you say - lots of women go into medicine. My wife is a Nurse, she works in the operating room with a bunch of different surgeons. Most of the surgeons are male - there is certainly no lack of sexual harassment or frat style attitudes (whatever the medical version of brogrammer is).
Really? I know plenty. I also know approximately zero who were not in a committed relationship (i.e. married or dating the person they later married) by about age 20 or earlier.
If its going to be anything like the Netflix recommendation engine then I feel like online dating will probably take a step backwards.
Everyone will get recommended the same stupid people they don't want to see over and over again.
I've never put a real picture of myself on Ok Cupid. Not just because I'm fat, though there is something to that theory. Many reasons. 1. I used to not have a digital camera. 2. I don't want people in my real life to know that I'm desperate enough for online dating. 3. The Web never forgets. I want to be annoymous. 4. I honestly think that there should be a difference to online dating than real dating. If you want to be preoccupied with looks, then the club scene is where you need to be. Can't the internet be a meeting of minds where what you have to say is more important than what you look like?
I'm not a hypocrite. I'm willing to meet a morbidly obese woman for coffee if she sends me an interesting email. If there's no attraction then thanks for having coffee, Goodbye. I thought the whole point of online dating was to set up meetings. Not yack back and forth through email for weeks on end for no outings.
So I used to have a blank picture profile for a while. Never had any kind of substantive results. I figured out that I'm deviating from the norm too much. So I put up a picture of someone else. Then I got a couple of emails and whatnot. Then my life changed. Then I made a new profile with a new picture. Here's the thing. I try to pick a photo of someone who I guess is about the same level of attractiveness as me. And now I'm worried that I picked a picture that's WAY more attractive than me because I get replies all the time.
I don't know if this is what it's always been like for attractive persons, or is now that I'm finally coming out of my shell and showing confidence (in what I write I guess) and that people are more receptive to me because I'm actually engaging? I think I'm having more success in real life too. It's hard to tell, because honestly before I was just kind of dead inside.
To everyone else out there that thinks they're not attractive or whatever. Just do what I do. Lie. People don't wanna date you because you tuned 56? Make a new profile that says you're 52. Fuck, make a new profile that says you're 27 with a picture to match. Email smoking hot twenty somethings. Just get in the habit of talking to beautiful girls. It's fun. Dating is a waste of time anyway right? You're lucky if you get one date. So why play by the rules? Maybe you'll learn something trying to butter up those attractive air head girls that you can apply to someone with whom you have real potential.
I dunno. What do you guys think? What's she gonna think when the guy in the picture doesn't show up and I'm there instead?
There are probably more people in the unusual circumstances who rely on online dating, whereas the typical cases can meet people the old fashioned way. Most dating sites don't even presume to support polygamous seekers, for instance... but what more honest way to approach that than to have a profile that explains it? Or in other cases, many men refuse to date single parents, or women over a certain age (doesn't matter if they are over that age themselves.) Those are the situations that would benefit most from online dating, as the bar scene doesn't cater to them.
1. Can not be bat shit crazy.
2. Not a midget. (How the hell did I end up on a blind date with a midget? It was like going out with a child, I think my 7 year old niece is taller. Before anybody asks it's true, I've actually been on a blind date with a little person, I'm not being sarcastic about that.)
Apparently it's going to be difficult to find both of those in 1 girl.

As it stands, I only get replies from bots and eharmony has scientifically proven that nobody on the face of the planet is compatible with me. Yes, I am serious.

Actually there is likely to be a positive correlation between attractiveness & intelligence, because we have evolved to look for healthy mates who are like to reproduce well. For example lack of symmetry tends (so there are plenty of counter examples, but they do not undermine the argument) to be associated with an underlying health problem. Also around the world men tend to consider women with a particular hip to waist ratio as being the most attractive - research found that more that women deviated from that ratio then the less likely they would be able to conceive, carry a baby successfully to term, or have a safe vaginal birth.
In the second world war the British found that the most effective way of determining if a young woman would be good at the job of evaluating reconnaissance taken by RAF planes was by looking at the girls's ankles - the work involved intense concentration for long hours. At the time they did not know why. I suspect now, it was because a shapely ankle correlate well with health and stamina - but feminists would be predisposed to jump to the wrong conclusions.
Certainly, when I was working at at with lots of PhD students, the girls seemed to be generally of above average beauty! (No I didn't attempt to date any of them, as I'm married and old enough to be their grandfather!)
I pretty much came in here to say this. People already game the system in so many intricate ways, but those ways at least are social engineering techniques that mean you at least have to have a clue about how people tick (and thus in a social situation, like a date, you can reasonably hold your own/not suck at being a conversationalist). But if you're optimizing against a machine algorithm the sky's the limit. Make a few fake profiles and hit yourself up to increase your attractiveness score, or convince your friends to do the same in kind. Figure out what keywords get you more attractive girls/guys, and build your profile around that. Then you finally end up on a date and...*pfft* now your out of your element. Then the dating site loses credibility and gets washed back into the primordial ooze from which it crawled.
