Large Scale Machine Learning with Python

Overview of this book

Large Python machine learning projects involve new problems associated with specialized machine learning architectures and designs that many data scientists have yet to tackle. But finding algorithms and designing and building platforms that deal with large sets of data is a growing need. Data scientists have to manage and maintain increasingly complex data projects, and with the rise of big data comes an increasing demand for computational and algorithmic efficiency. Large Scale Machine Learning with Python uncovers a new wave of machine learning algorithms that meet scalability demands together with a high predictive accuracy. Dive into scalable machine learning and the three forms of scalability. Speed up algorithms that can be used on a desktop computer with tips on parallelization and memory allocation. Get to grips with new algorithms that are specifically designed for large projects and can handle bigger files, and learn about machine learning in big data environments. We will also cover the most effective machine learning techniques on a map reduce framework in Hadoop and Spark in Python.

Convolutional Neural Networks in TensorFlow through Keras


Between this and the previous chapter, we have come quite a long way covering the most important topics in deep learning. We now understand how to construct architectures by stacking multiple layers in a neural network and how to discern and utilize backpropagation methods. We also covered the concept of unsupervised pretraining with stacked and denoising autoencoders. The next and really exciting step in deep learning is the rapidly evolving field of Convolutional Neural Networks (CNN), a method of building multilayered, locally connected networks. CNNs, commonly referred to as ConvNets, are so rapidly evolving at the time of writing this book that we literally had to rewrite and update this chapter within a month's timeframe. In this chapter, we will cover the most fundamental and important concepts behind CNNs so that we will be able to run some basic examples without becoming overwhelmed by the sometimes enormous complexity. However...
