Statistical algorithms | Filter theory
Least mean squares (LMS) algorithms are a class of adaptive filter used to mimic a desired filter by finding the filter coefficients that relate to producing the least mean square of the error signal (difference between the desired and the actual signal). It is a stochastic gradient descent method in that the filter is only adapted based on the error at the current time. It was invented in 1960 by Stanford University professor Bernard Widrow and his first Ph.D. student, Ted Hoff. (Wikipedia).

Least squares method for simple linear regression
In this video I show you how to derive the equations for the coefficients of the simple linear regression line. The least squares method for the simple linear regression line, requires the calculation of the intercept and the slope, commonly written as beta-sub-zero and beta-sub-one. Deriv

Finding the MMSE Filter Optimum Weights
The math of solving the MMSE problem to find the optimal weights. A linear algebra formulation is used to rewrite the mean-squared error as a perfect square, which allows the MMSE weights to be identified by inspection without defining gradients and. This is the matrix equivalent of the
