Hands-On Machine Learning with IBM Watson

By: James D. Miller

Overview of this book

IBM Cloud is a collection of cloud computing services for data analytics using machine learning and artificial intelligence (AI). This book is a complete guide to help you become well versed with machine learning on the IBM Cloud using Python. Hands-On Machine Learning with IBM Watson starts with supervised and unsupervised machine learning concepts, in addition to providing you with an overview of IBM Cloud and Watson Machine Learning. You'll gain insights into running various techniques, such as K-means clustering, K-nearest neighbor (KNN), and time series prediction in IBM Cloud with real-world examples. The book will then help you delve into creating a Spark pipeline in Watson Studio. You will also be guided through deep learning and neural network principles on the IBM Cloud using TensorFlow. With the help of NLP techniques, you can then brush up on building a chatbot. In later chapters, you will cover three powerful case studies, including the facial expression classification platform, the automated classification of lithofacies, and the multi-biometric identity authentication platform, helping you to become well versed with these methodologies. By the end of this book, you will be ready to build efficient machine learning solutions on the IBM Cloud and draw insights from the data at hand using real-world examples.

K-nearest neighbors

As the previous algorithm (KMeans) is an unsupervised learning methodology, the k-nearest neighbors (KNN) algorithm is a fundamentally simple to understand supervised machine learning methodology. The concept of the KNN algorithm is described commonly as classifying data by identifying its nearest neighbor or, my favorite analogy, you can identify or classify data by identifying who it associates most with or finding its closest neighbor.

The Python code

As we stated earlier, our objective is to demonstrate how to implement various types of ML algorithms within IBM Watson Studio, not provide the theory behind each algorithm; in addition to that, consistent with the last section, we will utilize an existing...
