SUMMARY

The discussion centers on the concept of convexity in optimization, particularly its significance in problems such as image segmentation. Convexity is crucial as it ensures that any local minimum is also a global minimum, simplifying the optimization process. The term "convexify" refers to transforming a non-convex problem into a convex one, which is often necessary for effective solution finding. Understanding the geometric definition of convexity and its implications for feasible solution sets in linear programming is essential for grasping its advantages.

PREREQUISITES
  • Understanding of convex and non-convex functions
  • Familiarity with optimization techniques
  • Knowledge of linear programming concepts

My supervisor always talks about how a problem is convex or its nonconvex and we want to convexify it.

I understand that convexity gives a lot of advantages for optimization, and I understand the geometric definition of convexity.

How does my supervisor know something is convex? Like a segmentation of an image for instance. And what advantages does convexity give you.

Your supervisor is using non-standard terminology so no one but he/she can tell for certain what is meant. I suspect that there is some set of points inherent in the problem (the set of "feasible solutions" to a linear programming problem, for example) and he/she is referring to the convexity of that set.
