4), let us take a careful look at it. Do you see a problem with this formulation? Suppose Least-Squares Solutions 35 the point sets are given with respect to another coordinate system. 4 (right). Thus, in the current form, our solution depends on the choice of coordinate system. This should not be the case. The best-fitting line should only depend on the arrangement of the points, and remain unchanged with respect to the point set as long as its arrangement remains fixed. We will come back to this problem later on.

However, often there are some isolated points in the given data set called outliers. An outlier is a data point that lies outside the overall pattern of the underlying distribution or data model. Suppose we are looking for a straight line best fitting a set of data points. Here we implicitly assume that the points do indeed come from a straight line, but allow for corruption due to noise. However, there can be isolated samples or points in the data that are actually not from the underlying model, a straight line in this case, that lie quite far away from it.

This is 36 Least-Squares Solutions indeed a good estimate of the underlying model if the points are samples arising from a line segment. 5)? As we will shortly see, this approach is not all that different from what we have learned for the linear case. 5: LS polynomial fit to a given set of points. The LS solution gives the best curve fit to a set of given points by optimizing over all curves from a family specified by a polynomial of the form y = f (x). Given a point set P := {pi }, say we want to find the bestfitting m-th order polynomial function represented by y = f (x) = m k k=0 ak x .
