We will be using K-Means Clustering or Hierarchical Agglomerative Clustering to cluster the dating profiles with one another. By doing so, we hope to provide these hypothetical users with more matches like themselves instead of profiles unlike their own. Now that we have an outline to begin creating this machine learning dating algorithm, we can begin coding it all out in Python!
Since publicly available dating profiles are rare or impossible to come by, which is understandable due to security and privacy risks, we will have to resort to fake dating profiles to test out our machine learning algorithm. The process of gathering these fake dating profiles is outlined in the article below:. Once we have our forged dating profiles, we can begin the practice of using Natural Language Processing NLP to explore and analyze our data, specifically the user bios. We have another article which details this entire procedure:.
With the data gathered and analyzed, we will be able to move on with the next exciting part of the project — Clustering! To begin, we must first import all the necessary libraries we will need in order for this clustering algorithm to run properly. We will also load in the Pandas DataFrame, which we created when we forged the fake dating profiles.
With our dataset good to go, we can begin the next step for our clustering algorithm. This will potentially decrease the time it takes to fit and transform our clustering algorithm to the dataset. Next, we will have to vectorize the bios we have from the fake profiles. With vectorization we will implementing two different approaches to see if they have significant effect on the clustering algorithm.
We will be experimenting with both approaches to find the optimum vectorization method. Here we have the option of either using CountVectorizer or TfidfVectorizer for vectorizing the dating profile bios. When the Bios have been vectorized and placed into their own DataFrame, we will concatenate them with the scaled dating categories to create a new DataFrame with all the features we need. Based on this final DF, we have more than features.
This technique will reduce the dimensionality of our dataset but still retain much of the variability or valuable statistical information. What we are doing here is fitting and transforming our last DF, then plotting the variance and the number of features. This plot will visually tell us how many features account for the variance.
These features will now be used instead of the original DF to fit to our clustering algorithm. In order to cluster our profiles together, we must first find the optimum number of clusters to create. The optimum number of clusters will be determined based on specific evaluation metrics which will quantify the performance of the clustering algorithms. Since there is no definite set number of clusters to create, we will be using a couple of different evaluation metrics to determine the optimum number of clusters.
These metrics each have their own advantages and disadvantages. The choice to use either one is purely subjective and you are free to use another metric if you choose. Below, we will be running some code that will run our clustering algorithm with differing amounts of clusters. By running this code, we will be going through several steps:. Also, there is an option to run both types of clustering algorithms in the loop: Hierarchical Agglomerative Clustering and KMeans Clustering.
There is an option to uncomment out the desired clustering algorithm. To evaluate the clustering algorithms, we will create an evaluation function to run on our list of scores. With this function we can evaluate the list of scores acquired and plot out the values to determine the optimum number of clusters.
Based on both of these charts and evaluation metrics, the optimum number of clusters seem to be For our final run of the algorithm, we will be using:. With these parameters or functions, we will be clustering our dating profiles and assigning each profile a number to determine which cluster they belong to.
With everything ready, we can finally discover the clustering assignments for each dating profile. Once we have run the code, we can create a new column containing the cluster assignments. This new DataFrame now shows the assignments for each dating profile. We have successfully clustered our dating profiles! We can now filter our selection in the DataFrame by selecting only specific Cluster numbers.
By utilizing an unsupervised machine learning technique such as Hierarchical Agglomerative Clustering , we were successfully able to cluster together over 5, different dating profiles. Feel free to change and experiment with the code to see if you could potentially improve the overall result. Hopefully, by the end of this article, you were able to learn more about NLP and unsupervised machine learning. There are other potential improvements to be made to this project such as implementing a way to include new user input data to see who they might potentially match or cluster with.
Perhaps create a dashboard to fully realize this clustering algorithm as a prototype dating app. Link to the Web Application. The pandemic has driven a lot of users to the apps, as the more traditional way of meeting someone the bars, the gyms, etc.
Hinge was launched in and has grown to be a popular app for the relationship-minded, particularly among the millennial and younger generation… Hinge is a mobile-only experience and employs a freemium model. Hinge focuses on users with a higher level of intent to enter into a relationship and its product is designed to reinforce that approach. From a user perspective, Hinge is kind of like Tinder, but less aggressive. You answer 3 questions of your choice that others see, and upload 6 pictures of yourself, like above.
It measures this based off your engagement and who engages with you, as well as matches you to people with similar preferences. The dating market is two-sided: one person seeks out another, with the platform serving to enable interaction. It broadly relies on network effects: the larger the pool the app the pulls from, the higher probability of finding a person that meets preferences. More specifically:.
Given n men and n women, where each person has ranked all members of the opposite sex in order of preference, marry the men and women together such that there are no two people of opposite sex who would both rather have each other than their current partners. When there are no such pairs of people, the set of marriages is deemed stable. Source: Wiki.
The Gale-Shapley algorithm solves this through a series of iterations in which element A proposes to their highest ranked element B. The matching is considered stable when there is no match A, B that prefer each other over their current partners. We need to match the bug to a tree, through stable pairings. So we have four bugs: a bumblebee, a ladybug, a caterpillar, and a butterfly. We also have four trees: a pinetree, a cactus, a tulip, and an oak tree. The bumblebee prefers the pinetree, the ladybug prefers the oak tree, caterpillar likes the cactus the most, and the butterfly likes the tulip.
The butterfly would be happier with the tulip, but because the tulip is with the caterpillar which it prefers over the butterfly the matching is stable. Thus, we have stable matches. Basically, everyone prefers each other. Hitsch et al wrote a comprehensive article applying the above algorithm to the online dating world in and their ultimate finding was:.
Our results suggest that the particular site that we study leads to approximately efficient matching outcomes within the set of stable matches , and that search frictions are mostly absent. Hence, the site appears to be efficiently designed…Based on the results obtained in this study, we conclude that online dating data provide valuable insights toward understanding the economic mechanisms underlying match formation and the formation of marriages.

This stable matching pairing is actually quite effective. So, I wanted to see what my data looked like. The data was super messy lots of nested lists , so I ended up converting into into a CSV and doing output through Excel. My profile is pretty dorky. Most of my pictures are me either wearing a pi shirt or doing yoga, but I do have a serious selfie in there.
Most people tend to comment about the breakfast food question, but most of the time, interactions are led by someone liking a picture. As you can see, there was a large pool initially, which was whittled down through interaction or lack thereof. There is a lot of analysis on the nuances of dating apps, including the weird science of attractiveness, in which. Women like men who rate themselves as five out of 10 as much as men who think they are 10 out of 10s, whereas men would ideally date someone who self-rates their physical appearance as eight out of Search costs are still relatively high on most apps, due to information asymmetry and the potential gaps in the matching process.
It does increase sample size of available partners, but can also work to depersonalize the entire exchange primarily through the gamification. However, online dating has become the most popular way that people meet their partners , as shown above.
People who have had a positive experience with the apps have cited the increased opportunity to meet people as the top upside, but dishonesty and misrepresentation as the biggest downside. Pictures and openness about intent seems to be the most important to users.
Overall, it seems that if someone was actively pursuing a relationship which I am not it seems the best thing to do is to optimize the algorithm: make a fun profile, be responsive, and engage actively.

This will potentially decrease the two different approaches to see apps and algorithms has been to dating match algorithm dataset. Odds of a single message vectorize the bios we have optimum vectorization method.
