BayesiaLab

What is BayesiaLab?

BayesiaLab is desktop software from Bayesia for building, analyzing and deploying Bayesian networks. The company describes it as a lab-style workspace used by scientists and analysts for simulation, optimization, analytics, knowledge modeling and machine learning. The platform spans three kinds of programs: desktop software, web applications such as the WebSimulator for sharing interactive models without an install, and the Bayesia Engine API that developers use to embed models in other applications. BayesiaLab Professional can be licensed by rental, perpetual purchase with a separate maintenance and support subscription, or prepaid elastic licensing, where usage hours are deducted while the program runs and unused hours expire. An Academic Edition and an Education Package are limited to accredited institutions, and a Code Export Module and other extensions are sold separately. Prices for the main licenses are set in the Bayesia store; several store items show euro prices.
