Challenge 20.1 – Using machine learning to predict Active vs Inactive customers
TracFone’s customers draw from diverse and vibrant backgrounds. For example, they may be proudly pragmatic who appreciate good value mobile service plans. Alternatively, they may be travelers that are temporarily visiting friends or family or forming new memories on their vacation to take home with them. They may even belong to financially fragile communities that have traditionally been underserved by the large wireless providers that required credit and long-term contracts. Ever since our inception in 1996, our focus has always been on providing Coverage And Access For All.
In the prepaid cellular service market that we pioneered in the USA, customers pay for service in advance of the month with no contracts or obligations to continue their service the following month. This gives our customers tremendous flexibility to manage their monthly spending and adapt to their shifting circumstances. They may continue to prepay the same amount for next month’s service, change to a different service plan, or let their service become Inactive.
A service going inactive may be expected for a customer temporarily visiting the USA. Meanwhile, financially fragile members of our community may become inactive for the month and later return with necessary funds to activate their service. An economically secure customer may choose to move to another one of TracFone’s other ten brands, or leave TracFone all together.
One of the challenges data scientists in TracFone contend with is predicting if a customer is likely to become inactive. Accurately predicting a customer’s future Active vs Inactive status allows us to recommend appropriate ways for them to continue their service. After all, cellular service is a necessary part of our modern lifestyle, and we want to do our best to keep our customers connected.
Can you build a model to predict if a service will continue to remain Active or become Inactive in two weeks?
Who can join in?
TracHack 20.1 participants will be students enrolled in the Master of Science in Business Analytics (MSBA) in A/Prof Daniel McGibney’s class. We hope to expand the participation in subsequent challenges (i.e. 20.2, 20.3, etc ). Drop us an email if you couldn’t participate this time and would want to participate in the next event.
When, where and how long?
TracHack 20.1 starts on April 8, 2020 and ends May 3, 2020. The teams will make three submissions of their solutions. Each submission will be scored and teams will be ranked by the AUC metric for leaderboard positions.
The winners of the challenge will be announced based on the ranking from the final submission. The top three teams with the highest AUC score will win cash prizes, fame and glory.
Even though the final ranking is based on the final submission, it is a good idea to validate the approach and solution along the way using each of the submission deadlines as checkpoints.
What happens when my team wins?
You win fame, glory and bragging rights. There are also cash prizes for the teams to go with trophies:
1st place team: $3,000
2nd place team: $2,000
3rd place team: $1,000
The winning teams will be required to make a 10-minute presentation at the award ceremony that describes their solution and how they tackled this problem.
