Abstract: We design new visual illusions by finding ``adversarial examples'' for principled models of human perception --- specifically, for probabilistic models, which treat vision as Bayesian inference. To perform this search efficiently, we design a \emph{differentiable} probabilistic programming language, whose API exposes MCMC inference as a first-class differentiable function. We demonstrate our method by automatically creating illusions for three features of human vision: color constancy, size constancy, and face perception.
