Machine Learning & Deep Learning Essentials with Spark and TensorFlow

Apache Spark, a significant component in the Hadoop Ecosystem, is a cluster computing engine used in Big Data. Building on top of the Hadoop YARN and HDFS ecosystem, offers order-of-magnitude faster processing for many in-memory computing tasks compared to Map/Reduce. It can be programmed in Java, Scala, Python, and R - the favorite languages of Data Scientists - along with SQL-based front ends. The first part of the course teaches performing Machine Learning at Scale using the popular Apache Spark framework. This course is intended for data scientists and software engineers, and assumes attendees have little or no previous experience with Machine Learning. This course explores popular machine learning algorithms from the ground up. Students will explore Apache Spark essentials, core machine learning concepts, regressions, classifications, clustering and more.
