Not sure if this was already asked but I have phone interview coming up. How can i best prepare for the interview?
Hi! These interviews tend to have two parts, a conceptual ML learning part and a coding part. For the first part, some concepts they recently asked about include:
-what’s overfitting? what causes it? how to deal with overfitting?
- closed form solution to linear and ridge regression? what about lasso?
- how to improve overfitting with decision trees?
- multiple decision trees
- difference between random forest and gradient boosting tree?
Coding part:
-average value for each layer in a binary tree
