最さい急きゅう降こう下か法ほう

noun

steepest descent method; gradient descent method; saddle point method

Mathematical optimization algorithm that finds a local minimum by moving in the direction of the negative gradient. In Japanese, 最急降下法 is the standard term; 'saddle point method' is a less common English equivalent sometimes used in physics contexts.

• 最さい急きゅう降こう下か法ほうは、機き械かい学がく習しゅうでよく使つかわれる最さい適てき化かアルゴリズムです。

  The steepest descent method is an optimization algorithm often used in machine learning.

• この関かん数すうの最さい小しょう値ちを求もとめるために、最さい急きゅう降こう下か法ほうを適てき用ようした。

  We applied the steepest descent method to find the minimum of this function.
