You should do whatever you like, but remember that domain knowledge and math skills are not mutually exclusive. If the problem you need to solve for a major customer or project happens to be in that 30%, it may come in handy.
Linear algebra and calculus (to a lesser degree) are foundational for a great many things. Got missing data? K-NN or nuclear norm matrix completion (or marginalizing over the rest) can help. Systems of differential equations? Use a matrix exponential.
You are free to do whatever you like. A bus driver doesn't need to know how to rebuild an engine. But if you want to race cars you'll get a lot further if you do know how.
- blahi 10y agoIf I have missing values, I can use multiple imputation or even simple averaging and the hit I will take will be negligible. I simply do not work in the remaining 30%. I can tell if the work is going to be above my head and refuse the project in those cases. So after all this back and forth, I still don't know if there is a book similar to RMS in scope, for Bayesian Nets.
