Like a mat. analysis used in machine learning in practice?

Question

Machine learning

Hello! In the process of studying math analysis, I came across the question: how exactly is this area of ​​​​mathematics (for example, the first wonderful limit / second wonderful limit / etc) used in machine learning? I would be grateful for a good example or explanation

Answer 1

It makes no sense to tie a theory/algorithms/formulas to a fictitious problem.
It is done - on the contrary: a specific problem is solved using the most optimal algorithm, and if there are such incomprehensible things as wonderful limits, then you need to study the necessary sections (with an understanding of everything that happens when solving this particular problem).
