Overview of this book

With an increasing interest in AI around the world, deep learning has attracted a great deal of public attention. Every day, deep learning algorithms are used broadly across different industries. The book will give you all the practical information available on the subject, including the best practices, using real-world use cases. You will learn to recognize and extract information to increase predictive accuracy and optimize results. Starting with a quick recap of important machine learning concepts, the book will delve straight into deep learning principles using Sci-kit learn. Moving ahead, you will learn to use the latest open source libraries such as Theano, Keras, Google's TensorFlow, and H20. Use this guide to uncover the difficulties of pattern recognition, scaling data with greater accuracy and discussing deep learning algorithms and techniques. Whether you want to dive deeper into Deep Learning, or want to investigate how to get more out of this powerful technology, you’ll find everything inside.

Summary


In this chapter, we went through a long journey of optimizations, tweaks, testing strategies, and engineering practices to turn our neural network into an intrusion detection data product.

In particular, we defined a data product as a system that extracts value from raw data and returns actionable knowledge as output.

We saw a few optimizations for training a deep neural network to be faster, scalable, and more robust. We addressed the problem of early saturation via weights initialization. Scalability using both a parallel multi-threading version of SGD and a distributed implementation in Map/Reduce. We saw how the H2O framework can leverage Apache Spark as the backend for computation via Sparkling Water.

We remarked the importance of testing and the difference between model validation and full end-to-end evaluation. Model validation is used to reject or accept a given model, or to select the best performing one. Likely, model validation metrics can be used for hyper-parameter tuning...
