How to understand the condition number during SVD decomposition?

[Yang Li]

It shows if the problem is ill-posed. We basically ignore results of the SVD if the problem is ill-posed (i.e. with large condition number). This stablize the early training phase.

Yes, thanks for your reply, and I know that the condition number is set to check whether the results of the SVD are valid, but may I ask what is the actual meaning of the computed condition number? Could you give some hints about it?

Thanks very much for your help.
