The probabilistic framework, which describes how to represent and manipulate uncertainty about models and predictions, has a central role in scientific data analysis, machine learning, robotics, cognitive science and artificial intelligence. His research interests are in artificial intelligence, machine learning, and data mining. Probabilistic relational models (PRMs) are a language for describing statistical models over typed relational domains. From a probabilistic perspective, knowledge is represented as degrees of belief, observations provide evidence for updating one's beliefs, and learning allows the mind to tune itself to statistics of the environment in which it operates. The target audience of this book is researchers and students in the artificial intelligence and machine learning area, and beyond. It can be very demanding in parts. The probabilistic approach has been responsible for most of the recent progress in artificial intelligence, such as voice recognition systems, or the system that recommends movies to Netflix subscribers. The core representation, including Bayesian and Markov networks and relational models; probabilistic inference algorithms, both exact and approximate; and, learning methods for both the parameters and the structure of graphical models. Hidden Markov Model(HMM) : Introduction.
