## Build and improve a series of consumer propensity models (who is likely to make the repeat purchase next week) using the dataset in the lecture</p>
### *You can use the following data or the combination to train and validate the model*
> (T)    X20210731\_Y20210807\_0827\_mp\_clean.csv
> (T-1) X20210724\_Y20210731\_0827\_mp\_clean.csv
> (T-2) X20210717\_Y20210724\_0827\_mp\_clean.csv
> Use (T+1) X20210807\_Y20210814\_0827\_mp\_clean\_wolabel.csv as the final prediction data, and submit the prediction 


### Based on your learning in question 1 to question 3, propose and build the best model based on T, T-1 and T-2 data, make the prediction for T+1 data, and submit the prediction!</p>
