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.

Analyzing further


This section will describe further analysis that can be performed on the data after visualization. For example, exploring cosine distance similarity between different word vectors.

Getting ready

The following link is a great blog on how cosine distance similarity works and also discusses some of the math involved:

How to do it...

Consider the following:

  • Various natural-language processing tasks can be performed using the different functions of Word2Vec. One of them is finding the most semantically similar words given a certain word (that is, word vectors that have a high cosine similarity or a short Euclidean distance between them). This can be done by using the most_similar function form Word2Vec, as shown in the following screenshot:
    This screenshots  all the closest words related to the word Lannister:
    This screenshot shows a list of all the words related to word Jon...
