1) Do these courses help in understanding or have applications in:
- Machine Learning
- Quantitative Finance, eg. Stochastic Calculus
- Numerical Analysis/Optimization
2) If I could only pick one course, which one would be more useful?
To reiterate my question, I'm asking whether linear algebra at a high level, or functional analysis has more applications to the three aforementioned subjects and what those applications are.
PS. I'm a first time poster; I read the criteria for asking questions and they say not to ask course selection questions. However, I tried to get around that by asking about the applications of the subjects. If these sorts of questions are not welcome, I will modify the question or take it down. Thanks for your help.
