Probabilities play a central role in modern pattern recognition. We have seen in Chapter 1 that probability theory can be expressed in terms of two simple equations corresponding to the sum rule and the product rule. All of the probabilistic infer-ence and learning manipulations discussed in this book, no matter how complex, amount to repeated application of these two equations. We could ...
