Modern Scala Projects

By: Ilango gurusamy

Overview of this book

Scala is both a functional programming and object-oriented programming language designed to express common programming patterns in a concise, readable, and type-safe way. Complete with step-by-step instructions, Modern Scala Projects will guide you in exploring Scala capabilities and learning best practices. Along the way, you'll build applications for professional contexts while understanding the core tasks and components. You’ll begin with a project for predicting the class of a flower by implementing a simple machine learning model. Next, you'll create a cancer diagnosis classification pipeline, followed by tackling projects delving into stock price prediction, spam filtering, fraud detection, and a recommendation engine. The focus will be on application of ML techniques that classify data and make predictions, with an emphasis on automating data workflows with the Spark ML pipeline API. The book also showcases the best of Scala’s functional libraries and other constructs to help you roll out your own scalable data processing frameworks. By the end of this Scala book, you’ll have a firm foundation in Scala programming and have built some interesting real-world projects to add to your portfolio.

Chapter 6. Build Flights Performance Prediction Model

Flight delays and cancellations are travel annoyances. Will a Chicago-bound flight arrive late causing a traveler to miss their connecting flight to Denver? Another traveler at Chicago Airport just learned that their connecting flight to Philly was delayed, perhaps even canceled. If both travelers could predict the odds of their respective experiences actually occurring, travel would get so much better.

That said, implementing a flight delay pipeline that can predict outcomes on the lines just described is the overarching learning objective of this chapter. The next section lists all the learning objectives in terms of topics covered in this chapter.

All learning objectives in this chapter depend on the following datasets compiled by the United States Department of Transportation. These are flight data, airline carrier data, and flight performance data, respectively.

Each topic covered in this chapter has specific learning objectives, broken...
