The driving force behind optimization in machine learning is the response from an internal function of the algorithm, called the cost function. ... Definition, Types, Nature ... Optimization problems can be divided into two categories, depending on whether the variables are continuous or discrete: • An optimization problem with discrete variables is known as a discrete optimization, in which an object such as an integer, permutation or graph must be found from a countable set. • A problem with continuous variables is known as a continuous optimization, in which an optimal value from a co…
WebOct 5, 2024 · Cost functions An optimization problem is described by a set of variables, each having a set, or range, of possible values. They describe the decisions that the optimization solver must make. A solution assigns a value to each of these variables. The variables describe the choice for each of the aforementioned decisions.
