This blog introduces how to use `Putty` to transfer files from Windows OS to Linux OS and reverse.
A good way to reduce overfitting is to regularize the model, which means the fewer degrees of freedom it has, the harder it will be for it to overfit the data. For a linear model, regularization is achieved by constraining the weights of the model. In this blog, I will talk about how to constrain the weights of Ridge Regression, Lasso Regression...
In this blog, I resumed characteristics of 3 different Gradient Descent algorithms: Batch Gradient Descent computes the gradients based on the full training set, it takes long time; Stochastic Gradient Descent picks just one instance of training set, it has a better chance of finding the global minimum than Batch GD; Mini-batch Gradient Descent ...
