Will Gaussian Mixture models still work if the number of components is greater than the number of datapoints?

I have a question about Gaussian Mixture Models

(for minimizing / maximizing a function subject to constraints)

Can anyone tell me the difference between interior point methods and gradient descent?

Why does differentiating a vector give a diagonal matrix?

Hi

Can anyone help me with this question: math.stackexchange.com/questions/542907/minimization-of-norms

but any hint on how to do this?

I understand how to compute the dual in a setting where there are constraints

It's also here: math.stackexchange.com/questions/541905/…

Can anyone help me find the dual of this optimization problem? $min_x 1/2 ||y-x||_2^2 + \lambda||x||_1 $

HOw is the double dual the original norm?

but I'm stuck

I've actually been trying to do this for sometime now

Can someone help me prove how the dual of the dual norm is the original norm?
