Using R iml Package to Improve Zillow’s House Price Estimates

In this Kaggle project, we attempted to improve Zestimate, Zillow’s estimates of house price, by predicting the log error between Zestimate and the sale price. Jason worked on this using Python. I used R, in particular the iml package. This package provides very handy functions to perform necessary operations such as cross-validation and parameter tuning. We ended up in top 10%, ranked 345th out of 3779. See my Kaggle kernel Kaggle kernel for more details.
