Least Square Approximation<br />
• Higher dimensional data are projected into<br />
lower dimensional space to suppress irrelevant<br />
details<br />
• Such projection is most conveniently<br />
accomplished by least square method<br />
Linear projection from 2D to 1D space:<br />
Original data distributed in a 2D space<br />
They can be approximated as a 1D line<br />
