Question: How to recognize users that will potentially bring profit to provider?

Input data: Logs of searches and clicks on site, logs from partner sites. The data will be merged and split on parts: 60% training, 20% test, 20% validation.

Features: The variables for model training that we’ll use as defining the output are: region, city, user actions and searches on site.

Algorithms: Deep Learning algorithm from H2O package.

Evaluation: The model will be evaluated based on number of predicted clicks + N * number of predicted conversions.

Model Usage: After being trained the Model will receive data on user and his actions on site and will provide probability that this user will click on ad.
