How to use data analysis for machine learning, part 2

In part 1, we went over how to use data visualization and data analysis prior to machine learning. For example, we discussed how to visualize the data to identify potential issues in the dataset, examine the variable distributions, etc. In this blog post, we’ll continue by building a very simple model and using data visualization to examine that model. Just a quick reminder: as I noted in part 1, we’re working with a very simple model. This is deliberately a “toy” model, which allows us to focus on the visualization/analysis aspect of the task without the added level of complexity that we’d inject by using a more advanced machine learning algorithm. Having said that, let’s dive in. Build a simple linear regression model Having explored our data in part 1,…
