						| Abstract [eng] | In order to make informed marketing decisions on customers' acquisition, retention strategies and amount worth to spend on them, business aim to know Gross Merchandise Value customer will create in a given future. In this thesis, besides already researched methods, the application of two- stage model using gradient boosted decision tree and two-stage feed forward neural network, where first stage is classification model to predict if customer will churn in a given future period and second stage is predicting GMV for those whom churn prediction is negative. Further, we propose a multi-output feed forward neural network for combined results: classification for churn and regression for GMV. Finally, models were created on real life customer-to-customer marketplace dataset and evaluated in between using the mean absolute error (MAE) and root-mean-squared-error (RMSE) metrics. |
