They will also learn about A\/B testing, but it will be somewhat an afterthought.\u003c\/p\u003e\n\u003cp\u003eThis book is different, it makes optimizing for reward at A\/B test time the central point of study. The methodology of A\/B testing is described in detail, highlighting both its significant strengths and potential limitations. The remainder of the book is developed from this point of view. This foundational nature will require a more comprehensive discussion of inferential and causal theory than other treatments, providing a stronger understanding about how the disparate machine learning techniques for recommendation fit together.\u003c\/p\u003e\n\u003cp\u003eUntil now, it has required a great deal of industry experience to identify why approaches based on (say) a direct implementation of reinforcement learning are likely to fail in production. Readers of this book should gain this intuition with less need to make painful mistakes in the wild.\u003c\/p\u003e\n\u003c\/div\u003e\u003cdiv\u003e\n\u003cp\u003eDavid Rohde is a researcher specializing in Bayesian inference, causality, and recommender systems.
