WebOct 8, 2015 · A stochastic process is a way of representing the evolution of some situation that can be characterized mathematically (by numbers, points in a graph, etc.) over time. They are of greatest help when you either don't know the exact rules of that evolution over time, or when the exact rule of that evolution is too complicated or costly to compute … WebStochastic processes are a way to describe and study the behaviour of systems that evolve in some random way. In this course, the evolution will mostly be with respect to a scalar parameter interpreted as time, so that we discuss the temporal evolution of the system.
