Markov Chain Monte Carlo, as the name implies, runs a Monte Carlo simulation using a Markov Chain that must satisfy some conditions so we always end up at our desired stationary distribution (the posterior) regardless of starting point. Pyro itself brings together the best of modern deep learning, Bayesian modeling, and software abstraction: it is a modern, universal, deep probabilistic programming language. Goals / Objectives Preserve, enhance, and distribute seed of nearly 47,000 accessions; identify plant traits and environments appropriate for use as selection criteria to genetically improve the productivity, stability, and quality of corn, forage, oat, popcorn, and soybean cultivars; develop and modify selection and breeding methods for genetic enhancement of genetically broad-based germplasm.
