Machine Learning on Kubernetes

By: Faisal Masood, Ross Brigoli

Overview of this book

MLOps is an emerging field that aims to bring repeatability, automation, and standardization of the software engineering domain to data science and machine learning engineering. By implementing MLOps with Kubernetes, data scientists, IT professionals, and data engineers can collaborate and build machine learning solutions that deliver business value for their organization. You'll begin by understanding the different components of a machine learning project. Then, you'll design and build a practical end-to-end machine learning project using open source software. As you progress, you'll understand the basics of MLOps and the value it can bring to machine learning projects. You will also gain experience in building, configuring, and using an open source, containerized machine learning platform. In later chapters, you will prepare data, build and deploy machine learning models, and automate workflow tasks using the same platform. Finally, the exercises in this book will help you get hands-on experience in Kubernetes and open source tools, such as JupyterHub, MLflow, and Airflow. By the end of this book, you'll have learned how to effectively build, train, and deploy a machine learning model using the machine learning platform you built.

Building and evaluating the ML model

Congratulations! You are now ready to train your model. You will first evaluate what set of algorithms will be a good fit for the given problem. Is it a regression or classification problem? How do you evaluate to see whether the model is achieving 75% correct predictability as described by the business?

Selecting evaluation criteria

Let's start with accuracy as the model evaluation criteria. This records how many times the predicted values are the same as the labels in the test dataset. However, if the dataset does not have the right variance, the model may guess the majority class for each example, which is effectively not learning anything about the minority class.

You decided to use the confusion matrix to see the accuracy for each class. Let's say you have 1,000 records in your data, out of which 50 are labeled as delayed. So, there are 950 examples with the on time label. Now, if the model correctly predicts 920 out of 950...
