Machine Learning Fundamentals

Overview of this book

As machine learning algorithms become popular, new tools that optimize these algorithms are also developed. Machine Learning Fundamentals explains you how to use the syntax of scikit-learn. You'll study the difference between supervised and unsupervised models, as well as the importance of choosing the appropriate algorithm for each dataset. You'll apply unsupervised clustering algorithms over real-world datasets, to discover patterns and profiles, and explore the process to solve an unsupervised machine learning problem. The focus of the book then shifts to supervised learning algorithms. You'll learn to implement different supervised algorithms and develop neural network structures using the scikit-learn package. You'll also learn how to perform coherent result analysis to improve the performance of the algorithm by tuning hyperparameters. By the end of this book, you will have gain all the skills required to start programming machine learning algorithms.

Data Visualization


Once data has been revised generically to ensure that it can be used for the desired purpose, it is time to load the dataset and use data visualization to further understand it. Data visualization is not a requirement for developing a machine-learning project, especially when dealing with datasets with hundreds or thousands of features. However, it has become an integral part of machine learning, mainly for visualizing the following:

  • Specific features that are causing trouble (for example, those that contain many missing or outlier values) and to understand how to deal with them

  • The results from the model, such as the clusters created or the number of predicted instances for each labeled category

  • The performance of the model in order to see the behavior along different iterations

Its popularity in the tasks detailed previously is explained by the fact that the human brain processes information easily when it is presented as charts or graphs, which allows us to have a general...
