Dear all,
How to express the following objective function with CVX?
\begin{equation}
\min_{z>0} z*ln(\frac{1}{N}\sum_{k=1}^{N} \exp{(\frac{k}{z})}-\alpha)
\end{equation}
It should be convex.
I also tried smooth_logsumexp in TFOCS and It always reports error in the “-” before \alpha.
Here \alpha is a negative constant.
Thank you in advance.
