Learning a probability distribution based on a random sample and sampling from a given distribution are two basic problems in statistics and machine learning. These problems have been studied intensively as two separate questions in the literature. In recent years, generative learning methods such as generative adversarial networks have been proven effective in learning distributions. In this talk, we consider the problems of sampling from a conditional distribution and sampling from an unnormalized distribution to illustrate that learning and sampling are two sides of the same coin in the context of generative learning. The key to the success of such an approach is the power of deep neural networks in approximating multidimensional functions. Numerical experiments on image generation using benchmark datasets and simulation from multimodal distributions demonstrate that generative Monte Carlo has the potential to be a useful addition to the toolbox for sampling.
