WebJan 8, 2024 · Bayesian Networks are a powerful IA tool that can be used in several problems where you need to mix data and expert knowledge. Unlike Machine Learning (that is solely based on data), BN brings the possibility to ask human about the causation laws (unidirectional) that exist in the context of the problem we want to solve. WebDAGitty — draw and analyze causal diagrams. DAGitty is a browser-based environment for creating, editing, and analyzing causal diagrams (also known as directed acyclic graphs or causal Bayesian networks). The focus is on the use of causal diagrams for minimizing bias in empirical studies in epidemiology and other disciplines.
