When looking for ways to improve your website, how do you decide which changes to make? And which changes to keep? This concise book shows you how to use Multiarmed Bandit algorithms to measure the real-world value of any modifications you make to your site. Author John Myles White shows you how this powerful class of algorithms can help you boost website traffic, convert visitors to customers, and increase many other measures of success.
This is the first developer-focused book on bandit algorithms, which were previously described only in research papers. Youâll quickly learn the benefits of several simple algorithmsâincluding the epsilon-Greedy, Softmax, and Upper Confidence Bound (UCB) algorithmsâby working through code examples written in Python, which you can easily adapt for deployment on your own website.
- Learn the basics of A/B testingâand recognize when itâs better to use bandit algorithms
- Develop a unit testing framework for debugging bandit algorithms
John Myles White is a PhD candidate in Psychology at Princeton. He studies pattern recognition, decision-making, and economic behavior using behavioral methods and fMRI. He is particularly interested in anomalies of value assessment.
