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.

Spam classification problem


Any email service should process incoming mail intelligently. This could be classifications that produces two distinct, sorted streams of email, ham and spam. Email processing at the sentry level entails a smart vetting process—a classification task that produces two distinct, sorted streams of email—ham and spam. Gmail's sophisticated spam filtering engine filters out spam by a classification process, fulfilling, in a proverbial sense, the separation of the wheat from the chaff.

Spam can be a pernicious phenomenon in our daily lives, which is intimately tied to an increasingly connected world. For example, a binary classification is an ongoing deceptive link to apparently innocent looking websites hosting malware. Readers can learn why a spam filter can minimize problems spam can cause. These are summarized as follows:

  • Unethical companies harvest email addresses from the web and send out a flood of bulk emails to people. A Gmail user, say, [email protected],...
