Overview of this book

Organizations these days need to integrate popular big data tools such as Apache Spark with highly efficient deep learning libraries if they’re looking to gain faster and more powerful insights from their data. With this book, you’ll discover over 80 recipes to help you train fast, enterprise-grade, deep learning models on Apache Spark. Each recipe addresses a specific problem, and offers a proven, best-practice solution to difficulties encountered while implementing various deep learning algorithms in a distributed environment. The book follows a systematic approach, featuring a balance of theory and tips with best practice solutions to assist you with training different types of neural networks such as convolutional neural networks (CNNs) and recurrent neural networks (RNNs). You’ll also have access to code written in TensorFlow and Keras that you can run on Spark to solve a variety of deep learning problems in computer vision and natural language processing (NLP), or tweak to tackle other problems encountered in deep learning. By the end of this book, you'll have the skills you need to train and deploy state-of-the-art deep learning models on Apache Spark.

Manipulating and merging the MovieLens datasets


We currently have four separate datasets that we are working with, but ultimately we would like to get it down to a single dataset. This chapter will focus on pairing down our datasets to one.

Getting ready

This section will not require any import of PySpark libraries but a background in SQL joins will come in handy, as we will explore multiple approaches to joining dataframes.

How to do it...

This section will walk through the following steps for joining dataframes in PySpark:

  1. Execute the following script to rename all field names in ratings, by appending a _1 to the end of the name:
for i in ratings.columns:
     ratings = ratings.withColumnRenamed(i, i+'_1') 
  1. Execute the following script to inner join the movies dataset to the ratings dataset, creating a new table called temp1:
temp1 = ratings.join(movies, ratings.movieId_1 == movies.movieId, how = 'inner')
  1. Execute the following script to inner join the temp1 dataset to the links dataset, creating...
