Scalable programming with Scala and Spark

Use Scala and Spark for data analysis, machine learning and analytics

What you'll learn:

• Use Spark for a variety of analytics and Machine Learning tasks
• Understand functional programming constructs in Scala
• Implement complex algorithms like PageRank or Music Recommendations
• Work with a variety of datasets from Airline delays to Twitter, Web graphs, Social networks and Product Ratings
• Use all the different features and libraries of Spark : RDDs, Dataframes, Spark SQL, MLlib, Spark Streaming and GraphX
• Write code in Scala REPL environments and build Scala applications with an IDE

Taught bya 4 person team including 2Stanford-educated, ex-Googlers and 2 ex-Flipkart Lead Analysts. This team has decades of practical experience in working with Java and with billions of rows of data.

Get your data to fly using Spark and Scalafor analytics, machine learning and data science

Let’s parse that.

What's Spark?If you are an analyst or a data scientist, you'reused to having multiple systems for working with data. SQL, Python, R, Java, etc. With Spark, you have a single engine where you can explore and play with large amounts of data, run machine learning algorithms and then use the same system to productionize your code.

Scala:Scala is a general purposeprogramming language - like Java or C++. It's functional programming nature and the availability of a REPLenvironment make it particularly suited for a distributed computing framework like Spark.

Analytics:Using Spark and Scala you can analyze and explore your data in an interactive environment with fast feedback. The course will show how to leverage the power of RDDs and Dataframes to manipulate data with ease.

Machine Learning and Data Science:Spark's core functionality and built-in libraries make it easy to implement complex algorithms like Recommendations with very few lines of code. We'll cover a variety of datasets and algorithms includingPageRank, MapReduceand Graph datasets.

What's Covered:

Scala Programming Constructs: Classes, Traits, First Class Functions, Closures, Currying, Case Classes

Lot's of cool stuff ..

• Music Recommendations using Alternating Least Squares and the Audioscrobbler dataset
• Dataframes and Spark SQL to work with Twitter data
• Usingthe PageRank algorithm with Google web graph dataset
• Using Spark Streaming for stream processing
• Working with graph data using theMarvel Social network dataset

.. and of course all the Spark basic and advanced features:

• Resilient Distributed Datasets, Transformations (map, filter, flatMap), Actions (reduce, aggregate)
• Pair RDDs , reduceByKey, combineByKey
• Broadcast and Accumulator variables
• Spark for MapReduce
• The Java API for Spark
• Spark SQL, Spark Streaming, MLlib and GraphX
