Q1 default scoring for Linear Regression and Decision Tree Regressor

Module 5. Decision tree models Wrap-up quiz
#1

Looks like R2 score is the default scoring for both Linear Regression and Decision Tree Regressor. It’s not obvious to me from the reference page on cross_validate which scoring is used by default for different models?

#2

yes r2 score is the default for regressor and accuracy score is the default for classifier.

You are using a regression score with a classifier. This is wrong indeed.
