ISIPTA is the primary international forum about theories and applications of imprecise probability. The symposium is open to contributions on all aspects of imprecise probability, which is a generic term for the many mathematical and statistical models and methods that allow us to measure chance or uncertainty without the restriction of sharp probabilities. This includes (but is not limited to) sets of probability measures, partial preference orderings, game-theoretic probability, choice functions, interval probabilities, belief functions, and possibility theory.
