Time Series chart

This is a simple chart used for measuring events over time or in other words it is a series of statistical observations that are recorded over time. Visualizing your data this way would help you figure out how the data changes with respect to time in the past and you can also make predictions regarding the values that might occur in the future when time changes. Let's now see some sample Time Series charts in action.

Before giving examples of time series charts, let's understand the dataset used for the time series chart examples.

All India seasonal and annual average temperature series dataset

In this dataset, we have India's seasonal temperature captured on monthly/annual basis from 1901 to 2015. The dataset is downloaded as a JSON file from https://data.gov.in/catalog/all-india-seasonal-and-annual-mean-temperature-series. You can also find the sample dataset in the GitHub code accompanied with this book.

This dataset comprises two json objects as shown next:

Mastering Machine Learning with Spark 2.x

Mastering Machine Learning with Spark 2.x

The purpose of machine learning is to build systems that learn from data. With the meteoric rise of machine learning, developers are now keen on finding out how can they make their Spark applications smarter. The book commences by defining machine learning primitives by the MLlib and H2O libraries. You will learn how to use Binary classification to detect the Higgs Boson particle in the huge amount of data produced by CERN particle collider and classify daily health activities using ensemble Methods for Multi-Class Classification. Finally, you will build different pattern mining models using MLlib, perform complex manipulation of DataFrames using Spark and Spark SQL, and deploy your app in a Spark streaming environment.
