Least Square Method(Least Mean Square)
Least Square Method(Least Mean Square) The way how to obtain parameters to minimize the sum of data and residual(error). In other words, to obtain parameters(a, b) with minimum E. - y = f(x) : Linear - ei : Residual(Error) - (xi, yi) : Data - a, b : Parameters y = f(x) : Linear Regression It can be expressed as below. Error Distance between the point and y. Sum of the square errors Matrix Equati..
