My practice codes for MAIF challenge, which is open-competition of machine learning and data science. This practice was managed by Machine Learning course in 2016 HEIG-VD & SNU Summer University, Switzerland.

Infer the annual insuarance fee from other given variables(known or unknown).

• data/ech_apprentisage.csv Training Data
• data/ech_test.csv Test Data

Using all given variables, train several models and merge the results using simple regressor. String variables are converted to binary strings.
