Mastering Spark for Data Science

By: Bifet, Morgan, Amend, Hallett, George

Overview of this book

Data science seeks to transform the world using data, and this is typically achieved through disrupting and changing real processes in real industries. In order to operate at this level you need to build data science solutions of substance –solutions that solve real problems. Spark has emerged as the big data platform of choice for data scientists due to its speed, scalability, and easy-to-use APIs. This book deep dives into using Spark to deliver production-grade data science solutions. This process is demonstrated by exploring the construction of a sophisticated global news analysis service that uses Spark to generate continuous geopolitical and current affairs insights.You will learn all about the core Spark APIs and take a comprehensive tour of advanced libraries, including Spark SQL, Spark Streaming, MLlib, and more. You will be introduced to advanced techniques and methods that will help you to construct commercial-grade data products. Focusing on a sequence of tutorials that deliver a working news intelligence service, you will learn about advanced Spark architectures, how to work with geographic data in Spark, and how to tune Spark algorithms so they scale linearly.

Summary

The purpose of this chapter was to cover different topics around time series, word embedding, sentiment analysis, graph theory, and anomaly detection. It's worth noting that the tweets used to illustrate the examples in no way reflect the authors' own opinions: "Whether or not America will be great again is out of scope here":(:( - sarcasm or not?

In the next chapter, we will cover an innovative approach to detect trends out of Time Series data using the TrendCalculus method. This will be used against market data, but can easily be applied in different use cases, including the Sentiment Time Series we built here.
