What is convex function?
A mathematical function where the line segment connecting any two points on the function's graph lies above or on the graph
convex function explained in plain English
Analogy
Imagine a bowl-shaped curve, where a marble rolled between any two points on the curve would always follow a path that is above or on the curve, never below it. This is similar to how a convex function behaves.
Example
A simple example of a convex function is the cost of producing a certain number of units of a product. As the number of units increases, the cost may increase at an increasing rate, resulting in a convex curve.
How is convex function used?
Convex functions are used in optimization problems, where the goal is to find the minimum or maximum of a function. They are also used in machine learning and artificial intelligence to model complex relationships between variables.
Common misconceptions about convex function
History
The concept of convex functions has been around for centuries, but it wasn't until the 20th century that they became a fundamental tool in optimization and machine learning.
