Gbm vs logistic regression.
Isn't gbm just trees? Been using it in spark for close to an year and never bothered to learn the difference. I just run both and choose the best algorithm.
I have been working on ML for close to two years and I can't answer most of these questions. Guess I am not cut out for Google
- vimarshk 9y agoThis is just a sample of the questions they ask. I think Google interviews are dense and go back to first principles which is what I have learned as well.
- Eridrus 9y agoThis seems like a set of questions for Analysts, rather then Engineers. If you apply for a ML SWE role, these are unlikely to be the questions you get, though with a company as large as Google, who knows what your interviewer will bust out. GBM is trees, and I think the question is to explain why you would want trees, but I think the trick for fitting arbitrary differentiable loss functions in a GBM is pretty nifty.
- ganeshkrishnan 9y agoIt's up to the interviewer to ask the questions I assume. I was the technical recruiter for IBM and I always asked abstract technical questions rather than something that can be googled
