This data was gathered from participants in experimental speed dating events from During the events, the attendees would 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:.

At the end of the evening, they each rated their romantic attraction to their potential long-term partner. As shown in Fig. This finding does not imply that men are especially concerned about the mates attractiveness.

How We Do It: We analyze the Speed Dating Experiment dataset from Kaggle.​com to find out what makes two people a match for each other.

The dataset is provided with its key, which is a Word document you will need to quickly go through to understand my work properly. This is optional, but if we decide to change the color of the ggplot afterwards, it could be useful. In this part of the analysis, we will clean the dataset and work on variables to have a better exploration of the dataset. This procedure includes various checks, imputations, type changes…. Which feature has the most missing values? How many unique values are present for this or this feature?

It is a very good help to understand and clean the data. If we take a closer look at the data, we notice that there are a lot of features which have exactly 79 missing values. It appears that nothing very interesting can be deducted from this. Indeed, most of the missing values are preferences of the people considered. Impossible to impute that! According to our DQR, there is one missing id in our dataset.

In this post, survey data collected from several speed dating events is analyzed. The events were conducted between and by two professors from Columbia University: Ray Fisman and Sheena Iyengar. In addition to questions about personal interests, the survey includes academic and occupational questions as well.

Before applying machine learning techniques to our dataset, we needed to prepare our dataset. In order to do that, we made changes on some features provided in the dataset. These changes were made since these features had numeric values. Additionally, we applied labeling to categorical features of dataset. Thus, this action was performed to avoid labeling numerical values wrong manner.

We removed other string valued features from our dataset.

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:.

Ideal Match Using Speed Dating Data. Word Count: I hereby certify that the information contained in this (my submission) is information.

Speed dating is a relative new concept that allows researchers to study various theories related to mate selection. A problem with current research is that it focuses on finding general trends and relationships between the attributes. This report explores the use of machine learning techniques to predict whether an individual will want to meet his partner again after the 4-minute meeting based on their attributes that were known before they met. It is shown that Random Forests perform better than Support Vector Machines and that extended attributes give better result for both classifiers.

Furthermore, it is observed that the more information is known about the individuals, the better a classifier performs. Clubbing preferences of the partner stands out as an important attribute, followed by the same preference for the individual.

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?

The dataset has 3, observations — two-way interactions between a participant and a partner. The data has been cleaned to ensure that only.

Abstract In this paper we perform a variety of analytical techniques on a speed dating dataset collected from — There have previously been papers published analyzing this dataset however we have focused on a previously unexplored area of the data; that of self-image and self-perception. We have evaluated whether the decision to meet again or not following a date can be predicted to any degree of certainty when focusing only on the self-ratings and partner ratings from the event.

Speed dating and self-image: Revisiting old data with New Eyes

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.

In short, we want to make it easy for non profit organisations to speak to volunteer data scientists so they can help them think through data problems as early as possible. Share the problem. So, rather than waiting until we have all the data, and a really well defined brief, each non-profit organisation had a chance to present their problem for 5 minutes, to a room of volunteer data scientists. Think through it together.

Next, each non-profit organisation was paired with a table of data scientists, and had 10 minutes to explore the problem together, completing a worksheet with prompts, to talk about:. The speed dating part. After 10 minutes was up, we introduced the speed dating part — we rotated the groups, matching the data scientist volunteers to a new non-profit, and repeated the process, until all the volunteers had spoke to all the non-profits.

By the end of the night, people from the non profits had a chance to think through their problem with nearly 25—30 skilled data professionals, leaving the event with a load of useful, structured feedback about the next steps they should take. If any volunteers or nonprofits get on particularly well together, the worksheets allowed a chance for data scientists to opt-in for a single follow up coffee to discuss in more detail. So, before data scientists can do any actual analysis, it ends up taking a lot of volunteer time to help collate data, clean it up, and work out how to explain the problem to others, before its possible to have an event like a hackday or similar where you might try solving the problem.

This limits how many non-profits we can help.
