Stochastic Optimization Techniques Neural networks are often trained stochastically, i.e. using a method where the objective function changes at each iteration. This stochastic variation is due to the model being trained on different data during each…

Stochastic Optimization 转载请注明作者:梦里风林 Github工程地址:https://github.com/ahangchen/GDLnotes 欢迎star,有问题可以到Issue区讨论 官方教程地址 视频/字幕下载 实践中大量机器学习都是通过梯度算子来求优化的 但有一些问题,最大的问题就是,梯度很难计算 我们要计算train loss,这需要基于整个数据集的数据做一个计算 而计算使 train loss 下降最快的调整方向需要的时间是计算train loss本身的三…
