![]() ![]() We generate random inputs by scattering grains over the square then perform a computation on each input (test whether it falls within the circle). In this procedure the domain of inputs is the square that circumscribes our circle. The ratio of the two counts is an estimate of the ratio of the two areas, which is pi/4.Count the number of objects inside the circle and the total number of objects.Uniformly scatter some objects of uniform size (grains of rice or sand) over the square.Draw a square on the ground, then inscribe a circle within it.Given that the circle and the square have a ratio of areas that is π/4, the value of π can be approximated using a Monte Carlo method: Perform a deterministic computation on the inputs.įor example, consider a circle inscribed in a unit square.Generate inputs randomly from a probability distribution over the domain."Monte Carlo methods vary, but tend to follow a particular pattern: Latent Class Mixture Model with Dirichlet Allocation.BCM-Ch06.1: Latent Class Model "Exam Scores".Mixture Model for the 'Seven Scientists' Problem.Mixture Models of pairs of Binomial Models.BCM-Ch04.1: Inferring a mean and a Standard Deviation.BCM-Ch03.6: Joint Distributions - The Survey Model.BCM-Ch03.4: Prior and Posterior Prediction.BCM-Ch03.2: Difference between Two Rates. ![]()
