Refer to Table 3.2, the information system table. Prepare a similar table for a perfect, or fully informative, information system— that is, an information system that perfectly reveals the true state of nature. Do the same for a non- informative information system— one that reveals nothing about the true state. Use the probabilities from the two tables you have prepared to revise state probabilities by means of Bayes’ theorem, using the prior probabilities and GN message given in Example . Comment on the results.
