In the previous post, I talked about using MapReduce and Spark for distributed model training. In this post, I will talk about parameter server and how it is used in distributed model training.
Let’s start with linear regression. Using established libraries such as scikit-learn, it is almost trivial to train a linear regression model. We can easily run the model training with a few hundred Megabytes of data on our laptop with a build-in CPU.
Now let’s think big.
