Hands-On Design Patterns and Best Practices with Julia

The template method pattern

The template method pattern is used to create a well-defined process that can use different kinds of algorithms or operations. As a template, it can be customized with whatever algorithm or functions the client requires.

Here, we will explore how the template method pattern can be utilized in a machine learning (ML) pipeline use case. For those who are unfamiliar with ML pipelines, here is a simplified version of what a data scientist might do:

A dataset is first split into two separate datasets for training and testing purposes. The training dataset is fed into a process that fits the data into a statistical model. ...
