In this chapter, we will deal with the question of how a series of data points (e.g., from physical measurements, experimental observations, stock market data, etc.) can be approximated by a simple function p(x) (e.g., polynomials). On the other hand, we want to clarify how complex functions can be approximated by simpler functions.

摘要

In this chapter, we will deal with the question of how a series of data points (e.g., from physical measurements, experimental observations, stock market data, etc.) can be approximated by a simple function p(x) (e.g., polynomials). On the other hand, we want to clarify how complex functions can be approximated by simpler functions.
