Brief
yenta is a professional networking app launched by Japanese startup Atrae that uses artificial intelligence (AI) to optimize profile matching for its users. In hosting this competition, Atrae strives to improve the AI it uses on its platform to enable yenta users to make new, valuable connections and expand their networks.
The goal of this competition is to optimize yenta’s matching algorithm by predicting the compatibility of two app users. This ensures that the app recommends the most relevant profiles to each user, and winning algorithms submitted for this competition may be used to optimize yenta’s profile recommendation algorithm. With your support, we aim to help people around the world make beneficial connections that last.
ABOUT YENTA
The goal of this contest is to improve the matching algorithm on Atrae’s professional networking app called yenta. Go to https://yenta.page.link/install_fbg to download and learn more about the yenta app.
*The yenta app is only available in Japan and India.
yenta is a matching app for building professional connections. Once you create a profile on the app, its native AI algorithm searches other users' profiles to find who you might be interested in and like to meet with. You swipe right on profiles you're interested in, and if the other person is also interested and swipes right on your profile, you can message, meet up, and submit a review for each other.
We encourage you to download the app to expand your network, get insider tips on new job opportunities, and gain insights that could give you an edge in this competition!

Data Breakdown
The goal of this competition is to predict the level of compatibility of two given users to improve the profile recommendation algorithm for yenta (link to download: https://yenta.page.link/install_fbg). For this purpose, we classify the level of compatibility between user A and user B into 4 categories:
• No Match = 0: At least one of either user A or user B swiped left on the other, meaning there is no possibility of a match.
• Match = 1: Both user A and user B swiped right on each other and matched.
• Matched and met but unfavorable review = 2: Both user A and user B swiped right on each other and matched, then met. After the meeting, user A gave user B a review of 1-3 out of 5 (an “unfavorable” review).
• Matched and met and favorable review = 3: Both user A and user B swiped right on each other and matched, then met. After the meeting, user A gave user B a review of 4-5 out of 5 (a “favorable” review).
To build this model, we provide 2 different types of data subsets: user data and interaction data.
Note that all of the data is anonymized through the use of alias IDs and multi-step vectorization models to ensure that user privacy is protected. IDs with low frequency are grouped into a category labelled “other” with an ID of 999999.
I. User data: These files are connected through the user_id column (e.g. 41245)
・ user_ages.csv:
# user_id: user ID
# age: user age (in years)
・ user_educations.csv:
# user_id: user ID
# school_id: school ID
# degree_id: degree ID (just for some users)
・ user_works.csv:
# user_id: user ID
# company_id: company ID
# industry_id: company's industry ID
(please note: one company can have multiple values; also, this column is user-selected, so values are not
necessarily tied to company ID, which means that the same company ID can have different values for different
users)
# over_1000_employees: variable indicating if the company has over 1000 employees or not
(please note: this column is user-selected, so values are not tied to company ID, which means the same company
ID can have different values for different users)
・ user_skills.csv:
# user_id: user ID
# skilld_id: skill ID
・ user_strengths.csv:
# user_id: user ID
# strength_id_x: the number of votes that the user has received as review from other users
・ user_purposes.csv:
# user_id: user ID
# purpose_id_x: whether the user marked "x" as a reason for using the app or not
・ user_self_intro_vectors_300dims.csv:
# user_id: user ID
# num_char: number of characters in the user's self-introduction text
# num_url: number of URLs in the user's self-introduction text
# num_emoji: number of emojis used in the user's self-introduction text
# self_intro_x: value for dimension "x" of the user's vectorized self-introduction text (out of 300 dimensions)
・ user_sessions.csv:
# user_id: user ID
# timestamp: session timestamp
II. Interaction data: These files are indexed by from-to user_id pairs (e.g. 12345-52462)
・ interaction_review_comments_300dims.csv:
# from-to: user ID of reviewer-user ID of reviewed
# review_comment_x: value for dimension "x" of the review comment (out of 300 dimensions)
・ interaction_swipes.csv:
# from-to: user ID of swiper-user ID of target
# timestamp: timestamp of the swipe event
# swipe_status: result of the swipe (-1 = not interested, 1 = interested)
・ interaction_review_strengths.csv:
# from-to: user ID of reviewer-user ID of reviewed
# strength_id: ID of the strength evaluated by the reviewer
III. Train and test files: In order to train the model, we provide a train.csv file with pairs of user IDs and their corresponding scores
・ train.csv:
# from-to: user ID of scorer-user ID of target
# score: compatibility score ID (0-3)
・ test.csv:
# from-to: user ID of scorer-user ID of target (to be predicted)
The solution file to be provided should follow this format: the from-to IDs should be the same IDs contained in the test.csv file, and they must be in the same order.
IMPORTANT NOTE: Score values on the submission file should be formatted with at least one decimal (e.g. 0.0 instead of 0, 1.0 instead of 1) or the system will not be able to score it properly.
• Submission.csv
from-to, score
6280229-6293525, 1.0
670384-50085, 2.0
2271906-4685859, 1.0
...
NOTE: The maximum number of submissions that can be made per day are 3 submission.csv files.
A few minutes after submitting your solution, you will be able to see the accuracy of your solution on the submission page over a subset of the test data.
Final competition results will be based on the Private Leaderboard results, and the winner will be the user at the top of the Private Leaderboard.
