about article "Meet the man behind Badoo, the world’s biggest dating app"






https://www.thetimes.co.uk/article/meet-andrey-andreev-the-man-behind-badoo-the-worlds-biggest-dating-app-f3qql99zs

‘the most mysterious businessman in the West’

Badoo, is available in 190 countries and has seven times more users than Tinder.

"The next big thing in dating, he says, is going to be lookalikes"

That is only for fun, not serious dating.
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/09/bumble-serves-catfish-in-new-york-to.html

Be alerted, be informed Bumble is backed by Badoo (80%, majority-owned by Badoo)
It is said Badoo is related to Russian mafia of white hat hackers in the spyware business.
Badoo is in big war with Tinder (Match Group)


When Match Group (fka IAC Personals) bought OKCupid (6+ years ago) for an astronomical amount of money, the OKCupid team had the task to copycat Badoo, but they failed in that mission.
IAC / Match Group "acquired" HatchLabs to "develop" Tinder copycat of Badoo.
Then Badoo backed Bumble to fight back and destroy Tinder (last December 2014).

A marriage can be stable, but miserable.



Gale-Shapley marriage problem does not take into account marital satisfaction.
https://www.ft.com/content/2a0c3f9a-b240-11e7-a398-73d59db9e399
Please remember: Gale-Shapley marriage problem is a HOAX. 
It does not take into account personality similarity between prospective mates.

FAILED and BIASED article "Mathematician reveals formula to find a perfect mate"
http://onlinedatingsoundbarrier.blogspot.com.ar/2015/03/failed-and-biased-article-mathematician.html


--------------
Compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment, and not meet other people with similar interests or political views.

At the paper  "Perceptions of Ideal and Former Partners' Personality and Similarity
The authors had written
".... mismatches in personality are a frequently mentioned cause for relationship break-up. If former partners indeed have dissimilar personalities, our findings underline how difficult it is for many people to select a mate with a similar personality, or, alternatively, how little value individuals put on finding a similar partner in terms of personality.
The present study's results, as well as the results found in previous studies (e.g., Eastwick & Finkel, 2008), may be used to educate people, especially singles, about what really matters in long-term relationships, for instance, similarity in personality, instead of complementarity."


The Online Dating Industry does not need a 10% improvement, a 50% improvement or a 100% improvement. It does need "a 100 times better improvement"
 
Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the Big Five model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 test instead and another method to calculate similarity.

High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
Without offering the NORMATIVE 16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.

"Blockchain Matching Platforms: An Innovative Way to Connect with Peers"


https://www.cryptocoinsnews.com/blockchain-matching-platforms-an-innovative-way-to-connect-with-peers/

Innovative? Where is exactly the innovation? Because
The 3 milestone discoveries of the 2001 - 2010 decade for Theories of Romantic Relationships Development are:

I) Several studies showing contraceptive pills users make different mate choices, on average, compared to non-users.
"Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"

II) People often report partner preferences that are not compatible with their choices in real life. (Behavioural recommender systems or other system that learns your preferences are useless)

III) What is important in attracting people to one another may not be important in making couples happy.
Compatibility is all about a high level on personality similarity between prospective mates for long term mating with commitment, and not meet other people with similar interests or political views.

At the paper  "Perceptions of Ideal and Former Partners' Personality and Similarity

about article and paper: Evidence That Online Dating Is Changing the Nature of Society

https://www.sciencealert.com/this-is-how-online-dating-has-changed-the-very-fabric-of-society

The Strength of Absent Ties: Social Integration via Online Dating
https://arxiv.org/abs/1709.10478

Please remember: Gale-Shapley marriage problem is a HOAX. It does not take into account personality similarity between prospective mates.
Also a marriage can be stable, but miserable.  Gale-Shapley marriage problem  does not take into account marital satisfaction.
Gale-Shapley marriage problem proposes stable marriage as an economic function (as a complex mental process).
They propose: a stable marriage can be predicted using mainly Gale_Shapley algorithm, General Equilibrium Theory and Non_cooperative Game Theory.
The Gale-Shapley algorithm is not good enough to solve the stable marriage problem because is based on initial preferences (attraction, fantasies, infatuation) and does not take into account temporal patterns of relationship variables.

http://onlinedatingsoundbarrier.blogspot.com.ar/2017/04/coffeemeetsbagel-dating-apps-and-gale.html

There's no evidence that (actual) matching algorithms work, Dr. Finkel says.
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/09/theres-no-evidence-that-actual-matching.html

 

Lack Of Innovation and Decadence can summarize the Online Dating Industry.
C-Level executives are more worried about their golf scores than their company’s long term strategy and innovations.
C-level executives are cooking barbecues under the water (selling smoke) and not paying attention to latest research from Academics which could be beneficial for the Online Dating Industry.

The 3 milestone discoveries of the 2001 - 2010 decade for Theories of Romantic Relationships Development are:

I) Several studies showing contraceptive pills users make different mate choices, on average, compared to non-users.
"Only short-term but not long-term partner preferences tend to vary with the menstrual cycle"

Kaspersky August 2017 research: Dangerous Liaisons: is everyone doing it online?









https://www.kaspersky.com/blog/online-dating-report/

Main Findings

  •     As many as one-in-three people are dating online.
  •     People turn to online dating for a variety of reasons – 48% do it for fun, while some look for more meaningful relationships.
  •     People share information with others too easily when they are dating online, with a quarter (25%) admitting they share their full name publicly on their dating profile. 
  •     Even though lying is one of the most hated aspects of online dating, 57% of online daters lie to each other, faking a range of attributes such as their names, marital status, location and appearance.
  •     People are concerned for their safety when they date online, with some of the main concerns involving worries about IT security – for example, 63% are concerned about the device they use for online dating becoming infected and 61% are concerned about their data being stolen or leaked from the dating app or service itself.
  •     These concerns are well-founded – 55% have experienced some form of threat or problem while dating online. And, people that use online dating are twice as likely to experience an IT security incident than people that don’t (41% vs 20%), primarily due to their increased level of online activity in general.
  •     Protection is also an issue for people that indulge in online dating. Just 27% of online daters use a security solution to protect their device and 16% do nothing at all to protect themselves as they see no risk.

His / Her face may be swollen due to subclinical hypothyroidism


https://www.nytimes.com/2017/10/09/science/stanford-sexual-orientation-study.html
https://ww2.kqed.org/futureofyou/2017/09/13/can-facial-recognition-detect-sexual-orientation-controversial-stanford-study-now-under-ethical-review/



Images/photos used in the samples do not take into account:
* Normally cycling women versus women using hormonal contraceptive methods.
"Ovulatory cycle and changes in face width: How women can tell when other females are ovulating using clues in their face - and how they may then try to hide their partners from the 'threat' of these fertile ladies (Women's attractiveness changes with estradiol and progesterone across the ovulatory cycle)"
* Her face may be swollen by a pregnancy.
* His / Her face may be swollen due to subclinical hypothyroidism.
* Persons with facial surgery or even worse Photoshopped / altered / retouched images (nose, lips, eyebrows) can introduce bias in the algorithm.

Also from the original research:
(208) Facial images. We obtained facial images from public profiles posted on a U.S. dating
(209) website. We recorded 130,741 images of 36,630 men and 170,360 images of 38,593 women
(210) between the ages of 18 and 40, who reported their location as the U.S. Gay and heterosexual
(211) people were represented in equal numbers. Their sexual orientation was established based on the
(212) gender of the partners that they were looking for (according to their profiles).


"Gay and heterosexual people were represented in equal numbers. "


Perhaps it is a flaw. Gay people are OVERrepresented in the sample.
Perhaps Gay people should be less than 10% in the sample.

If in real world heterosexual people are 90% of any REAL / REPRESENTATIVE sample of any real population, and 10% are only Gay and Bisexual, it will be easy to any algorithm to achieve 90% precision detecting heterosexual people!
It only needs to say all of them are heterosexual people and it will fail for a 10%,  i.e. 90% precision !

ABOUT Science of Love series presents Helen Fisher,


‘leading expert on love and attraction’
http://www.themaneater.com/stories/2017/10/9/science-love-series-presents-helen-fisher-leading-/

During December 2004, Dr. Helen Fisher was contacted by the people from Match to create Chemistry, the last innovation at Match, a compatibility matching method.

Please remember: the Chemistry personality test designed by Dr. Helen Fisher during 2004 is IPSATIVE, and not NORMATIVE.
It is only useful for entertainment purposes.
IPSATIVE TESTS ARE OBSOLETE SINCE YEARS.

I remember I had seen two draft papers from Chemistry:
The first clearly shows:
a) that Chemistry has a low successful "1.2.3 MEET in person step-by-step process", low successful first meeting rate for its members.
b) its matching method only reported early stage attraction between prospective mates and after the first meeting; in some persons attraction reduces its level OR worse even, morphs/metamorphoses to rejection. i.e. it is working only for short term mating!!!

The second shows:
a) the high serotonin type (Builder) who is attracted to people like themselves and the high dopamine type (Explorer) who also is attracted to people like themselves, could be looking for a LONG term romantic relationship.
and
b) the high estrogen Negotiator who is attracted to the high testosterone Director and vice versa, could be looking for a SHORT term romantic relationship.

The persons who used Chemistry, meet in person, and after that want to continue dating, is only a very small percentage of them. Less than 6% reach the first meeting in person stage. Of that 6% who reach the first meeting in person stage, not known exactly the percentage of persons who want to continue dating, but I suspect it is very low.

The key to long-lasting romance is STRICT PERSONALITY SIMILARITY and not "meet other people with similar interests".

"They're not the only ones using fake profiles," says Marc Lesnick, organizer of iDate, the industry's largest trade show. "It's definitely pervasive."

But Lesnick, the iDate organizer, says there’s no doubting who’s up to such tricks. “Everyone in the industry knows who the good players are and who bad players are,” he says. “Eventually the bad guys will get found out and get caught. This is fraud.” But when I ask him to name names, like many in the business, he declines. “I have to bite my lip,” he says. “Some of them come to my event.”

"you are more likely to find something in common and avoid the “body-shopping” culture of Tinder etc."

"something in common"?
If man A likes playing cards and woman B also likes playing cards, that does not mean man A likes woman B, or woman B can like man A with the same intensity or interest.

Personality, User Preferences and Behavior in Recommender systems
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/09/personality-user-preferences-and.html



Personality Based Recommender Systems are the next generation of recommender systems because they perform far better than Behavioural ones (past actions and pattern of personal preferences)
 

That is the only way to improve recommender systems, to include the personality traits of their users.
http://onlinedatingsoundbarrier.blogspot.com.ar/2017/01/paper-comparative-study-of-people-to_14.html  
 

They need to calculate personality similarity between users but there are different formulas to calculate similarity.

In case you did not notice, recommender systems are morphing to compatibility matching engines, as the same used in the Online Dating Industry for years, with low success rates until now because they mostly use the Big Five model to assess personality and the Pearson correlation coefficient to calculate similarity.
Please remember: Personality traits are highly stable in persons over 25 years old to 45 years old.
 


Which is the RIGHT approach to innovate in the Personality Based Recommender Systems Arena?
 
The same approach to innovate in the Online Dating Industry == 16PF5 test or similar to assess personality traits and a new method to calculate similarity between quantized patterns.
Online Dating sites have very big databases, in the range of 20,000,000 (twenty million) profiles, so the Big Five model or the HEXACO model are not enough for predictive purposes. That is why I suggest the 16PF5 test instead and another method to calculate similarity.

High precision in matching algorithms is precisely the key to open the door and leave the infancy of compatibility testing.
Without offering the NORMATIVE 16PF5 (or similar test measuring exactly the 16 personality factors) for serious dating, it will be impossible to innovate and revolutionize the Online Dating Industry.
