Implement machine learning algorithms and evaluate how well they perform with the Scala programming language

Programmers face multiple challenges while implementing ML; dealing with unstructured data and picking the proper ML model are among the hardest.

In this course we will go through day-to-day challenges that programmers face when implementing ML pipelines and consider different approaches and models to solve complex problems.

You will learn about the most effective machine learning techniques and implement them in your favor. You will implement algorithms in practical hands-on projects, building data models and understanding how they work by using different types of algorithm.

Each section of the course deals with a specific machine learning problem and analysis and gives you insights by using real-world datasets.

By the end of this course, you will be able to take huge datasets, extract features from it, and apply a machine learning model that is well suited to your problem.

This is a step-by-step and fast-paced guide that will help you learn how to create a ML model using the Apache Spark ML toolkit. With this practical approach, you will take your skills to the next level and will be able to create ML pipelines effectively.
