Building machine learning models

“

- [Instructor] All right. So we've spent quite a bit of time now seeing just how to work with data in Java and we've come to a very exciting part of the course where we're going to start actually building data science models using Java. So before we get into that, what I want to do is talk a little bit about the process of building models. And first of all, we're going to talk about what models are, but we're also going to talk about just some concerns to keep in mind when we're doing so. So the first question to ask ourselves is, what exactly are models? Models really are simplified representations of reality that are created to serve some sort of purpose. And in data science, generally that purpose is to make predictions. I'll talk about what I mean by that in just a second here. But generally when we think of models as simplified representations, I found that it really helps conceptually to understand this as when we…
