Uncertainty and negation—Information theoretic applications

The negation of a probability distribution developed by Yager and Liu deals with the uncertainty when the probability of a particular event is equally distributed among the other alternatives. In this case, intuitively the uncertainty associated with that particular event should be equally distributed among the uncertainty associated with the other alternatives. However, for verifying this, we need to develop uncertainty measures that will measure the uncertainty associated with the negation of a probability distribution. In the present study, we have developed measures analogous to the well known Shannon entropy function and the Kullback Leibler’s divergence for determining the uncertainty related with the negation and studied its properties. Finally, we have derived the Baye’s thoerem associated with the negation of probabilities of a sequence of events.     

The 22nd IEEE International Conference on Advanced Information Networking and Applications

Sponsored by IEEE Computer Society TCDP As one of the most important international conferences sponsored by the TCDP of the IEEE Computer Society, the International Conference on Advanced Information Networking and Applications （AINA-08） will be held in Ginowan City （URL http//www.city.ginowan.okinawa.jp/2735/2410.html）, Okinawa, Japan, on March 25-28, 2008. The conference covers theory, design and application of computer networks and distributed computing systems. Aside from the regular presentations, the conference will include keynote addresses with speakers from both industry and academia.

News comment — parties,bus tours and trips to McDonald's

Maintaining a fine tradition, Visa held a hugely enjoyable evening soiree at the recent CardTech/SecurTech show in Orlando. There were contacts to be made, and fine food and drink flowed throughout. Thank you Visa. Amid the jollity, a round of speeches were made, during which we were all assured that despite the lower attendance figures at this year’s show, much work was being performed behind the scenes in private meetings. This was certainly a relief because the event had indeed seemed flat this year, leaving the distinct feeling that war, viruses and difficult economic conditions had taken its toll on the smart card industry.This is a short news story only.
