Overview of this book

Machine learning is a subset of AI that aims to make modern-day computer systems smarter and more intelligent. The real power of machine learning resides in its algorithms, which make even the most difficult things capable of being handled by machines. However, with the advancement in the technology and requirements of data, machines will have to be smarter than they are today to meet the overwhelming data needs; mastering these algorithms and using them optimally is the need of the hour. Mastering Machine Learning Algorithms is your complete guide to quickly getting to grips with popular machine learning algorithms. You will be introduced to the most widely used algorithms in supervised, unsupervised, and semi-supervised machine learning, and will learn how to use them in the best possible manner. Ranging from Bayesian models to the MCMC algorithm to Hidden Markov models, this book will teach you how to extract features from your dataset and perform dimensionality reduction by making use of Python-based libraries such as scikit-learn v0.19.1. You will also learn how to use Keras and TensorFlow 1.x to train effective neural networks. If you are looking for a single resource to study, implement, and solve end-to-end machine learning problems and use-cases, this is the book you need.

Transfer learning


We have discussed how deep learning is fundamentally based on gray-box models that learn how to associate input patterns to specific classification/regression outcomes. All the processing pipeline that is often employed to prepare the data for specific detections is absorbed by the complexity of the neural architecture. However, the price to pay for high accuracies is a proportionally large number of training samples. State-of-the-art visual networks are trained with millions of images and, obviously, each of them must be properly labeled. Even if there are many free datasets that can be employed to train several models, many specific scenarios need hard preparatory work that sometimes is very difficult to achieve.

Luckily, deep neural architectures are hierarchical models that learn in a structured way. As we have seen in the examples of deep convolutional networks, the first layers become more and more sensitive to detect low-level features, while the higher ones concentrate...
