Compute the minimum square error for f(x) = |x|/pi (-pi<x<pi) and trigonometric polynomials if degree 1,2,3,4,5
Homework Answers
Summary
:Since the given function is an odd function,we first find the
Fourier coefficients and then we find the Fourier series of f(x)
with summation going up to N instead of infinity.Here N is the
degree of polynomial.

PLEASE USE PYTHON training error should strictly decrease as the degree of the hypothesis polynomials increases. That is because any high degree polynomial can "simulate" a lower degree polynomial by making it's high order coefficients zero. Thus nothing is lost and something might be gained by increasing the degree. But the code below shows that in-sample error actually starts to increase on our dataset for polynomials of very high degree. Why do you think this happens? CODE BELOW: ## Numerical...
