Myths & Facts
In this project our main concern are Myths & Facts related to the methodological and modeling aspects of IGDT. Most of the relevant material is discussed in the old site.
Our immediate goal here is to explain the basic facts in a non-technical way. For a preliminary examination of the issues involved, go through this 2007 presentation, where some of these myths and facts are discussed.
For the record, consider these two points regarding this presentation:
- Prof. Yacob Ben-Haim, the Father of IGDT, attended this presentation.
- The organisers of the conference objected to the subtitle of the lecture, so this subtitle was not displayed in the official program of the conference.
And to give you a taste of what Myths & Facts we are talking about here, consider this:
- Myth # 1: When IGDT was created, back in the late 1990s, it was radically different from all other decision theories that were available at the time.
- Myth # 2: IGDT robustness model is a proper tool for the treatment of severe uncertainties of the type postulated by the theory.
- Myth # 3 IGDT robustness analysis is not a worst case analysis.
- Myth # 4 IGDT robust decision making model is not a maximin model.
The corresponding facts are as follows:
- Fact # 1: IGDT is a simple case of Wald's famous Maximin paradigm (circa 1940).
- Fact # 2: IGDT robustness model is incompatible with the severety postulated by the theory.
- Fact # 3 IGDT robustness analysis is definitely a (local) worst case analysis.
- Fact # 4 IGDT robust decision making model is definitely a simple maximin model.
The peer-reviewed literature already provides formal, rigorous proofs of the validity of these facts. Our plan is to discuss these facts in great detail right here (but not now). Stay tuned.
