in. A fter swiping endlessly through hundreds of dating profiles and not matching with a single one, one might start to wonder how these profiles are even showing up on their phone. All of these profiles are not the type they are looking for. They have been swiping for hours or even days and have not found any success.
They might start asking:. Dating site data analytics dating algorithms used to show dati n g profiles might seem broken to plenty of people who are tired of swiping left when they should be matching. Every dating site and app probably utilize their own secret dating algorithm meant to optimize matches among their users. But sometimes it feels like it is just showing random users to one another with no explanation. How can we learn more about and also combat this issue?
By using a little something called Machine Learning. We could use machine learning to expedite the matchmaking process among users within dating apps. With machine learning, profiles can potentially be clustered together with other similar profiles. This will reduce the of profiles that are not compatible with one another. From these clusters, users can find other users more like them. The machine learning clustering process has been covered in the article below:. Take a moment to read it if you want to know how we were able to achieve clustered groups of dating profiles.
Using the data from the article above, we were able to successfully obtain the clustered dating profiles in a convenient Pandas DataFrame. In this DataFrame we have one profile for each row and at the end, we can see the clustered group they belong to after applying Hierarchical Agglomerative Clustering to the dataset. Each profile belongs to a specific cluster or group. However, these groups could use some refinement.
With the clustered profile data, we can further refine the by sorting each profile based on how similar they are to one another. This process might be quicker and easier than you may think. This is done so that our Dating site data analytics can be applicable to any Dating site data analytics from the dataset.
Once we have our randomly selected cluster, we can narrow Dating site data analytics the entire dataset to just include those rows with the selected cluster. With our selected clustered group narrowed down, the next step involves vectorizing the bios in that group. The vectorizer we are using for this is the same one we used to create our initial clustered Dating site data analytics — CountVectorizer. The vectorizer variable was instantiated ly when we vectorized the first dataset, which can be observed in the article above.
By vectorizing the Bios, we are creating a binary matrix that includes the words in each bio. After ing the two DataFrame together, we are left with vectorized bios and the categorical columns:. From here we can begin to find users that are most similar with one another. Once we have created a DataFrame filled binary values and s, we can begin to find the correlations among the dating profiles. Every dating profile has a unique index from which we can use for reference. In the beginning, we had a total of dating profiles. After clustering and narrowing down the DataFrame to the selected cluster, the of dating profiles can range from to Throughout the entire process, the index for the dating profiles remained the same.
Now, we can use each index for reference to every dating profile. With each index representing a unique dating profile, we can find similar or correlated users to each profile. This is achieved by running one line of code to create a correlation matrix. The first thing we needed to do was to transpose the DataFrame in order to have the columns and indices switch. This is done so that the correlation method we use applied to the indices and not the columns.
Once we have transposed the DF we can apply the. This correlation matrix contains numerical values which were calculated using the Pearson Correlation method. Values closer to 1 are positively Dating site data analytics with each other which is why you will see 1. From here you can see where we are going when it comes to finding similar users when using this correlation matrix. The first line in the code block above selects a random dating profile or user from the correlation matrix.
From there, we can select the column with the selected user and sort the users within the column so that it will only return the top 10 most correlated users excluding the selected index itself. We can see the top 10 most similar users to our randomly selected user. This can be run again with another cluster group and another profile or user. If this were a dating app, the user would be able to see the top 10 most similar users to themselves. This would hopefully reduce swiping time, frustration, and increase matches among the users of our hypothetical dating app.
Within those groups, the algorithm would sort the profiles based on their correlation score. Finally, it would be able to present users with dating profiles most similar to themselves. A potential next step would be trying to incorporate new data to our machine learning matchmaker.
Maybe have a new user input their own custom data and see how they would match with these fake dating profiles. Connect with me: linkedin. Your home for data science.
