Other arguably AI techniques such as Bayesian networks and data mining [21,148] are not discussed. Probabilistic Artificial Intelligence (Fall ’19) How can we build systems that perform well in uncertain environments and unforeseen situations? How can we build systems that learn from experience in order to improve their performance? Eighteenth Conference on Uncertainty in Artificial Intelligence (UAI02), Edmonton, Canada, August 2002. Learning Bayesian networks is NP-complete. Probability theory describes probabilities in terms of a probability space, typically assigning a value between 0 and 1, known as the probability measure, and a set of outcomes known as the sample space.
