This project reproduces the price optimization work done in "Optimization Beyond Prediction: Prescriptive Price Optimization". Instead of generalised additive models, I have used prophet time series model to predict the sales as a function of product's price and other features of importance.
The open source data set can be found at https://www.dunnhumby.com/careers/engineering/sourcefiles under "Breakfast at the Frat: A Time Series Analysis".
