WebJul 31, 2024 · We discussed one very useful property of the gradient flow corresponding to the evolution of the Fokker-Planck equation, namely “displacement convexity”. This is a generalization of the classical notion of convexity, due to McCann, to the case of a dynamics on a metric space which asserts that there is convexity along geodesics. This ... Web随机梯度下降虽然提高了计算效率，降低了计算开销，但是由于每次迭代只随机选择一个样本， 因此随机性比较大，所以下降过程中非常曲折 (图片来自《动手学深度学习》)，. 所以，样本的随机性会带来很多噪声，我们可以选取一定数目的样本组成一个小批量 ...
