Data Science at eHarmony — A Generalized Framework For Personalizationby Jonathan Morra
Director, Data Science
Data Science has always been a focus at eHarmony but recently many more business units have needed data driven models. In order to serve our modeling needs eHarmony has developed and open sourced a data transformation and model representation framework called Aloha. Aloha allows eHarmony to decouple engineering, model evaluation, from data science side, model creation. We have also embraced Apache Spark as an efficient way to create Aloha models for multiple business needs. This has allowed rapid modeling in areas such as personalized match making, models for our “What-If” product, fraud detection models, and email timing models.
