Python Machine Learning By Example - Third Edition

By: Yuxi (Hayden) Liu

Overview of this book

Python Machine Learning By Example, Third Edition serves as a comprehensive gateway into the world of machine learning (ML). With six new chapters, on topics including movie recommendation engine development with Naïve Bayes, recognizing faces with support vector machine, predicting stock prices with artificial neural networks, categorizing images of clothing with convolutional neural networks, predicting with sequences using recurring neural networks, and leveraging reinforcement learning for making decisions, the book has been considerably updated for the latest enterprise requirements. At the same time, this book provides actionable insights on the key fundamentals of ML with Python programming. Hayden applies his expertise to demonstrate implementations of algorithms in Python, both from scratch and with libraries. Each chapter walks through an industry-adopted application. With the help of realistic examples, you will gain an understanding of the mechanics of ML techniques in areas such as exploratory data analysis, feature engineering, classification, regression, clustering, and NLP. By the end of this ML Python book, you will have gained a broad picture of the ML ecosystem and will be well-versed in the best practices of applying ML techniques to solve problems.

Making Predictions with Sequences Using Recurrent Neural Networks

In the previous chapter, we focused on convolutional neural networks (CNNs) and used them to deal with image-related tasks. In this chapter, we will explore recurrent neural networks (RNNs), which are suitable for sequential data and time-dependent data, such as daily temperature, DNA sequences, and customers' shopping transactions over time. You will learn how the recurrent architecture works and see variants of the model. We will then work on their applications, including sentiment analysis and text generation. Finally, as a bonus section, we will cover a recent state-of-the-art sequential learning model: the Transformer.

We will cover the following topics in this chapter:

  • Sequential learning by RNNs
  • Mechanisms and training of RNNs
  • Different types of RNNs
  • Long Short-Term Memory RNNs
  • RNNs for sentiment analysis
  • RNNs for text generation
  • Self-attention and the Transformer...
