Geometric Aspects of Conditional Independence and Information

Workshop Topics

  1. Algebraic statistics, algebraic varieties and conditional independence.
  2. Causality, Bayesian networks and graph separation criteria for conditional independence.
  3. Learning, causal (conditional) independence, causal information flows and networks.
  4. Geometric aspects of information, decision and entropic quantities.
  5. Information-theoretical inequalities and their applications in information theory, networks, cryptology and quantum settings.
