Advanced Machine Learning with Python

Overview of this book

Designed to take you on a guided tour of the most relevant and powerful machine learning techniques in use today by top data scientists, this book is just what you need to push your Python algorithms to maximum potential. Clear examples and detailed code samples demonstrate deep learning techniques, semi-supervised learning, and more - all whilst working with real-world applications that include image, music, text, and financial data. The machine learning techniques covered in this book are at the forefront of commercial practice. They are applicable now for the first time in contexts such as image recognition, NLP and web search, computational creativity, and commercial/financial data modeling. Deep Learning algorithms and ensembles of models are in use by data scientists at top tech and digital companies, but the skills needed to apply them successfully, while in high demand, are still scarce. This book is designed to take the reader on a guided tour of the most relevant and powerful machine learning techniques. Clear descriptions of how techniques work and detailed code examples demonstrate deep learning techniques, semi-supervised learning and more, in real world applications. We will also learn about NumPy and Theano. By this end of this book, you will learn a set of advanced Machine Learning techniques and acquire a broad set of powerful skills in the area of feature selection & feature engineering.

The quotes at the start of this chapter were sourced from the highly-readable Kaggle blog, No Free Hunch. Refer to http://blog.kaggle.com/2014/08/01/learning-from-the-best/.

There are many good resources for understanding NLP tasks. One fairly thorough, eight-part piece, is available online at http://textminingonline.com/dive-into-nltk-part-i-getting-started-with-nltk.

If you're keen to get started, one great option is to try Kaggle's for Knowledge NLP task, which is perfectly suited as a testbed for the techniques described in this chapter: https://www.kaggle.com/c/word2vec-nlp-tutorial/details/part-1-for-beginners-bag-of-words.

The Kaggle contest cited in this chapter is available at https://www.kaggle.com/c/detecting-insults-in-social-commentary.

For readers interested in further description of the ROC curve and the AUC measure, consider Tom Fawcett's excellent introduction, available at https://ccrma.stanford.edu/workshops/mir2009/references/ROCintro.pdf.
