Modern Scala Projects

By: 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.

LR breast cancer pipeline

Before getting down to the implementation of a logistic regression pipeline, refer back to the earlier table in section Breast cancer dataset at a glance where nine breast cancer tissue sample characteristics (features) are listed, along with one class column. To recap, those characteristics or features are listed as follows for context:

  • clump_thickness
  • size_uniformity
  • shape_uniformity
  • marginal_adhesion
  • epithelial_size
  • bare_nucleoli
  • bland_chromatin
  • normal_nucleoli
  • mitoses

Now, let's get down to high-level formulation of the logistic regression approach in terms of what it is meant to achieve. The following diagram represents the elements of such a formulation at a high level:
