In this course, you'll learn how to use Spark from Python! Spark is a tool for doing parallel computation with large datasets and it integrates well with Python. PySpark is the Python package that makes the magic happen. You'll use this package to work with data about flights from Portland and Seattle. You'll learn to wrangle this data and build a whole machine learning pipeline to predict whether or not flights will be delayed. Get ready to put some Spark in your Python code and dive into the world of high-performance machine learning!
Getting to know PySparkFree
In this chapter, you'll learn how Spark manages data and how can you read and write tables from Python.
In this chapter, you'll learn about the pyspark.sql module, which provides optimized data queries to your Spark session.
Getting started with machine learning pipelines
PySpark has built-in, cutting-edge machine learning routines, along with utilities to create full machine learning pipelines. You'll learn about them in this chapter.Machine Learning Pipelines50 xpJoin the DataFrames100 xpData types50 xpString to integer100 xpCreate a new column100 xpMaking a Boolean100 xpStrings and factors50 xpCarrier100 xpDestination100 xpAssemble a vector100 xpCreate the pipeline100 xpTest vs. Train50 xpTransform the data100 xpSplit the data100 xp
Model tuning and selection
In this last chapter, you'll apply what you've learned to create a model that predicts which flights will be delayed.
