R: Unleash Machine Learning Techniques

Summary

In this chapter, we covered a lot of ground! We started with a discussion about how trends are detected and predicted in the retail vertical. Then we dived into what market basket analysis really means and the core concepts, mathematical formulae underlying the algorithms, and the critical metrics which are used to evaluate the results obtained from the algorithms, notably, support, confidence, and lift. We also discussed the most popular techniques used for analysis, including contingency matrix evaluation, frequent itemset generation, and association rule mining. Next, we talked about how to make data driven decisions using market basket analysis. Finally, we implemented our own algorithms and also used some of the popular libraries ...
