In this post, the classification technique of logistic regression is introduced, alongside a discussion of revealed preferences. This is done using a dataset on speed dating, generated experimentally as part of a paper by two professors at Columbia University. A topic near and dear to all single hearts and some coupled the world over: what does the opposite sex desire? In this post, we make an attempt to disentangle the deceit, duplicity and downright dishonesty that so fills the romantic realm, while also learning about the concept of revealed preferences and the logistic regression model. In recent years, classification models have become perhaps the most exciting application of modern statistical learning techniques. It is classification that underpins the most familiar of machine learning technologies eg. In these contexts, classification goes by the name of supervised learning , though the fundamental problem remains exactly the same: given input data, we want to use some kind of model to predict an output.
Exploring Speed Dating
Data was gathered from participants who were mostly students in speed dating events from During the events, the participants have a four minute first date with every other participant of the opposite sex. At the end of their four minutes, participants were asked if they would like to see their date again. They were also asked to rate their date on six attributes: Attractiveness, Sincerity, Intelligence, Fun, Ambition, and Shared Interests.
There are 21 speed dating events in the data set.

The dataset used for this paper was gathered by an American Business School, during Speed Dating events from to The dates lasted.
Data was collected through a speed dating experiment conducted by Columbia professors, Ray Fisman and Sheena Iyengar. The data was collected from at various speed dating events. Every date was four minutes long and every participant was asked if they would like to see that person again. We had information on demographics, dating habits, self-perception, beliefs on what others find valuable in a mate and lifestyle information.
The majority of the population was white. Participants were asked how important race was on a scale of , 1 being not important at all and 10 being very important, most said it was not important to them. So I decided to run the analysis for different groups. So who was the pickiest?

During a series of experiments conducted by the Columbia Business School professors Ray Fisman and Sheena Iyengar from to , over participants were asked to have a four-minute first date with other participants of the opposite sex, rate their attractiveness, sincerity, intelligence, fun, ambition, and shared Interests, and answer the question whether they would go on another date with their partners again.
The dataset was found on Kaggle and it contains questionnaire answers including demographics, dating habits, self-perception and ratings across key attributes, as well as dating decisions. Various data analyses have been performed with this dataset and insights range from gender differences in mate selection to racial preferences in dating.

The trial is set up to walk users through all the cool features this software offers while tapping into the power of machine learning to discover if love at first sight is authentic or absurd. Initial visualizations of speed dating data. Here you can quickly see that even people who are super social and go out frequently tend to prefer group activities to individual dates. Another thing that jumps out at me is that we can already see one of the most important attributes to finding THE ONE: how fun a person is.
Automated analysis of attributes that influence a match. This visualization reveals that out of approximately 4, speed dates, ended in a match The biggest influencers are how fun the male was, if the male shared interests with the female, how attractive the male was and how fun the female was. We also see the probability of a match. For example, the first group listed on the left shows Want to see which are the best predictors? Sign up for the free trial!

Today, finding a date is not a challenge — finding a match is probably the issue. In —, Columbia University ran a speed-dating experiment where they tracked 21 speed dating sessions for mostly young adults meeting people of the opposite sex. I was interested in finding out what it was about someone during that short interaction that determined whether or not someone viewed them as a match.
The dataset at the link above is quite substantial — over 8, observations with almost datapoints for each. However, I was only interested in the speed dates themselves, and so I simplified the data and uploaded a smaller version of the dataset to my Github account here. We can work out from the key that:. We can leave the first four columns out of any analysis we do. Our outcome variable here is dec. I’m interested in the rest as potential explanatory variables.
Before I start to do any analysis, I want to check if any of these variables are highly collinear – ie, have very high correlations. If two variables are measuring pretty much the same thing, I should probably remove one of them. But none of these get up really high eg past 0.
Applying Machine Learning Techniques to Speed Dating Dataset
Women put greater weight on the intelligence and the race of partner, while men respond more to physical attractiveness. Finally, male selectivity is invariant to group size, while female selectivity is strongly increasing in group size. The dataset is substantial with over 8, observations for answers to twenty something survey questions. With questions like How do you measure up?
