Hands-On Machine Learning with Scala and Spark

Video description

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

About This Video

  • Learn how to extract ML features from unstructured data for input to ML models so you can build models for any input data
  • Leverage Spark's Powerful ML toolkit to build models by learning how to choose the best model for your problem
  • Use Deep Learning methods with Apache Spark to stay on the cutting edge of ML techniques

In Detail

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.
