Therefore, the following code may not be documented/written in a way that is optimal... if you have any questions regarding this project, please do not hesitate to contact any of the group members listed above.
For many businesses, only a small fraction of customers produce the majority of the revenue. Therefore, identifying these potentially revenue-generating customers is critical for developing effective marketing strategies. Our project used visitor data from the online Google Merchandise Store to predict future customer revenue. Given that the vast majority of visitors never purchase anything in the future, we used a two-model approach: first, a logistic regression was used to quantify the probability that a given customer would make a purchase in the future, and second, a random forest was used to estimate the amount of money that a given customer was going to spend under the assumption that they did make a purchase in the future. By multiplying these two values together, we were able to estimate the expected value of any given customer with an accuracy that approximates the best-performing models to date.

./data/
- this is a directory added to the
.gitignore
, given that the files insde are too large to upload to GitHub in the traditional way. - the directory should contain the following files, all downloaded directly from the Kaggle competition website:
sample_submission_v2.csv
test_v2.csv
train_v2.csv
- the directory also contains other large data files that are generated in the notebooks described below
- this is a directory added to the
-
single-model-approach.ipynb
- contains the code for a single model approach that predicts fututre revenue using only a random forrest regressor for a subset of all visitors
- contains the code that performs the data exploration, feature engineering and the regression model
-
regression-model-feature-engineering.ipynb
- contains the code that performs the data exploration and feature engineering for the regression model
-
exploratory-regression-models.ipynb
- contains the code that tests various machine learning algorithms for the regression model
train_df_X.csv
- feature engineered training datasets for input into the regression machine learning algorithms
