Title: Naive Bayes Classification II
Summary
The Chapters 3 to 6 describe classification use cases and introduce the k-nearest neighbors (k-NN) and Naive Bayes learning algorithms. Chapter 3 applies k-NN for the evaluation of teaching assistants. In Chapter 4 k-NN is used to classify different glass types based on chemical components and the RapidMiner process is extended by Principal Component Analysis (PCA) to better pre-process the data and to improve the classification accuracy. Chapter 5 explains Naive Bayes as an algorithm for generating classification models and uses this modeling technique to generate a credit approval model to decide whether a credit loan for which a potential or existing customer applies should be approved or not, i.e. whether it is likely that the customer will pay back the credit loan as desired or not. Chapter 6 uses Naive Bayes to rank applications for nursery schools, introduces the RapidMiner operator for importing Excel sheets, and provides further explanations of Naive Bayes.
