What is the relationship between PCA and LDA/QDA?
I was asked to explain one of my machine learning projects from a big data point of view as in the speed variations in spark vs hadoop etc
What is the difference between L1 and L2 regularization?
Had an HR round and then a technical round where we talked about projects and then a case study. The issue is that the case study is a tough problem that they are dealing with; that is, something they have a whole team dedicated to and have been thinking about for months to years. Yet you are supposed to solve it in just a few minutes! So it really is not a fair assessment but that's how all tech interviews are today. One thing was the interviewer kept interrupting and didn't let me finish so I just figured he was trying to drive me toward to a set of exploratory questions on the case study. I did answer every question but got turned down.
