Convexity
With KKT-conditions, we have already got some powerful tools to analysis the local minimizers, but when is a local minimizer also a global one? In a special category of optimization problems, the convex optimization, this is always true. In the f...

We are going to have a look at some advanced topics Optimality Conditions for Unconstrained Optimization Problems
on convexity, gradient descent and other related stuffs.
Fréchet Differentiatio...
In this post, we basically extend the discussions in Optimization Learning Notes 6 on Gradient Descent Method (GDM).
We have already seen that Descent Direction is a important concept of GDM. However, why do we choose the negative...
