PPT-Computer vision: models, learning and inference

Chapter 2 Introduction to probability Please send errata to sprincecsuclacuk Random variables A random variable x denotes a quantity that is uncertain May be result of experiment flipping a coin or a real world measurements measuring temperature. washingtonedu Abstract Coarseto64257ne approaches use sequences of increasingly 64257ne approximations to control the complexity of inference and learning These techniques are often used in NLP and vision applications However no coarseto64257ne infer Chapter 14 .
