Title: | Improved Bounds on the Moments of Guessing Cost | Authors: | Arslan, Suayb S. Haytaoglu, Elif |
Publisher: | Ieee | Series/Report no.: | IEEE International Symposium on Information Theory | Abstract: | Guessing a random variable with finite or countably infinite support in which each selection leads to a positive cost value has recently been studied within the context of "guessing cost". In those studies, similar to standard guesswork, upper and lower bounds for the rho-th moment of guessing cost are described in terms of the known measure Renyi's entropy. In this study, we non-trivially improve the known bounds using previous techniques along with new notions such as balancing cost. We have demonstrated that the novel lower bound proposed in this work, achieves 5.84%, 18.47% higher values than that of the known lower bound for rho = 1 and rho = 5, respectively. As for the upper bound, the novel expression provides 10.93%, 5.54% lower values than that of the previously presented bounds for rho = 1 and rho = 5, respectively. | URI: | https://doi.org/10.1109/ISIT50566.2022.9834714 | ISBN: | 9781665421607 9781665421591 |
