比如 UC Berkeley的一篇论文就在Conclusion中写道: Despite the fact that our experimental evidence demonstrates that adaptive methods are not advantageous for machine learning, the Adam algorithm remains incredibly popular. We are not sure exactly as to why …… 无奈与酸楚之情溢于言表。 这是为什么呢?
在《机器学习 线性回归(Machine Learning Linear Regression)》一文中,我们主要介绍了最小二乘线性回归算法以及简单地介绍了梯度下降法。现在,让我们来实践一下吧。 先来回顾一下用最小二乘法求解参数的公式:。 (其中:,,) 再来看一下随机梯度下降法(Stochastic
Despite the fact that our experimental evidence demonstrates that adaptive methods are not advantageous for machine learning, the Adam algorithm remains incredibly popular. We are not sure exactly as to why …… 无奈与酸楚之情溢于言表。 这是为什么呢?难道平平淡淡才是真?
Stochastic Gradient Descent (SGD, or 1-SGD in our notation) is probably the most popular family of optimisation algorithms used in machine learning on large data sets due to its ability to optimise efficiently with respect to the number of complete training set data touches (epochs) used. ...

Stochastic Gradient Descent (SGD), which is an optimization to use a random data in learning to reduce the computation load drastically. Stochastic Average Gradient (SAG), which is a SGD-based algorithm to minimize stochastic step to average. Momentum Gradient Descent (MGD), which is an ...
What, When, Where, Why (but not How or Who)– Community tips, tricks, etc. for when to use which algorithm in what situations, what to watch out for in terms of errors. That is, practical advice on using Mahout for your problems. ...
