Projects

Infinite Agency -- Using Machine Learning to Improve Ad Impressions -- https://github.com/erdos2n/Capstone

Demonstrated the efficiency of multi-arm bandit in impression modeling vs A/B testing and also applied machine learning to attribution models. After showing the benefits of multi-arm bandit, I began using weighted attribution models that highlight each ad’s contribution on the path to conversion. These insights helped campaign efficiency, effectiveness and brought the ROI up for the client.

MDP Hackathon -- Patient/Doctor Recommender -- github.com/erdos2n/Hackerthon-Athena2017

Used a K-Means cluster and recommender system to rate doctors to clients so that they may receive the best care possible.
