# What are support values in a support vector machine?

I started reading up on SVM and very little is defined of what are support values. I reckon it's they are denoted as $$\alpha$$ in most formulations.

In the least-squares SVM (LS-SVM) the non-zero Lagrange multipliers ($$\alpha$$) are the support values. The corresponding data points are the support vectors. Johan Suykens explains this in Least Squares Support Vector Machines.
