Sgd with minibatch
Weba benefit over Minibatch-SGD, and that upon using uniform weights SLowcal-SGD per-forms worse compared to Minibatch SGD! We elaborate on this in Appendix J. 4 Proof Sketch for Theorem 3.2 Proof Sketch for Theorem 3.2. As a starting point for the analysis, for every iteration t ∈ [T] we will define the averages of (wi t,x i t,g i WebSGD全名 stochastic gradient descent， 即随机梯度下降。 不过这里的SGD其实跟MBGD (minibatch gradient descent)是一个意思,即随机抽取一批样本,以此为根据来更新参数. 具体实现: 需要:学习速率 ϵ, 初始参数 θ 每步迭代过程: 1. 从训练集中的随机抽取一批容量为m的样本 {x1,…,xm},以及相关的输出yi 2. 计算梯度和误差并更新参数: 优点: 训练速度快,对于很大的 …
