Building Recommendation System with Scala and Apache Spark [Tutorial]

Recommendation systems can be defined as software applications that draw out and learn from data such as preferences, their actions (clicks, for example), browsing history, and generated recommendations, which are products that the system determines are appealing to the user in the immediate future. In this tutorial, we will learn to build a recommendation system with Scala and Apache Spark. This article is an excerpt taken from Modern Scala Projects written Ilango Gurusamy. In the preceding diagram, can be thought of as a recommendation ecosystem, where the recommendation system is at the heart of it. Implementation is documented in the following subsections.
