Optimization through first-order derivatives
WebDec 21, 2024 · Gradient Descent is the most common optimization algorithm in machine learning and deep learning. It is a first-order optimization algorithm. This means it only takes into account the first derivative when performing the updates on the parameters. WebJan 22, 2015 · 4 Answers Sorted by: 28 Suppose you have a differentiable function f ( x), which you want to optimize by choosing x. If f ( x) is utility or profit, then you want to choose x (i.e. consumption bundle or quantity produced) to make the value of f as large as possible.
