By: Giuseppe Bonaccorso

Overview of this book

In this book, you will learn all the important machine learning algorithms that are commonly used in the field of data science. These algorithms can be used for supervised as well as unsupervised learning, reinforcement learning, and semi-supervised learning. The algorithms that are covered in this book are linear regression, logistic regression, SVM, naïve Bayes, k-means, random forest, TensorFlow and feature engineering. In this book, you will how to use these algorithms to resolve your problems, and how they work. This book will also introduce you to natural language processing and recommendation systems, which help you to run multiple algorithms simultaneously. On completion of the book, you will know how to pick the right machine learning algorithm for clustering, classification, or regression for your problem

Ensemble learning


Until now, we have trained models on single instances, iterating an algorithm in order to minimize a target loss function. This approach is based on so-called strong learners, or methods that are optimized to solve a specific problem by looking for the best possible solution. Another approach is based on a set of weak learners that can be trained in parallel or sequentially (with slight modifications on the parameters) and used as an ensemble based on a majority vote or the averaging of results. These methods can be classified into two main categories:

  • Bagged (or Bootstrap) trees: In this case, the ensemble is built completely. The training process is based on a random selection of the splits and the predictions are based on a majority vote. Random forests are an example of bagged tree ensembles.
  • Boosted trees: The ensemble is built sequentially, focusing on the samples that have been previously misclassified. Examples of boosted trees are AdaBoost and gradient tree boosting...
