Taylor Expansion for the Entropy Rate of Hidden Markov Chains
We study the entropy rate of a hidden Markov process, defined by observing the output of a symmetric channel whose input is a first order Markov process. Although this definition is very simple, obtaining the exact amount of entropy rate in calculation is an open problem. We introduce some probability matrices based on Markov chain's and channel's parameters. Then, we try to obtain an estimate ...
متن کاملHowling for the moon.
Rennard and Vestbo have sounded a ringing call to arms. Instead of trying to make minor improvements in the rate of decline of spirometry in patients with chronic obstructive pulmonary disease (COPD), they call for an all out effort to find a cure. Their arguments have attractions, but we believe that the evidence shows it would be easier to hatch out chickens from a plate of scrambled eggs tha...
متن کاملExplaining the moon illusion.
An old explanation of the moon illusion holds that various cues place the horizon moon at an effectively greater distance than the elevated moon. Although both moons have the same angular size, the horizon moon must be perceived as larger. More recent explanations hold that differences in accommodation or other factors cause the elevated moon to appear smaller. As a result of this illusory diff...
متن کاملVoices of the moon.
Professor Geoffrey Chamberlain, FRCOG, is chairman of the department of obstetrics and gynaecology at St George's Hospital Medical School, London. Enzyme linked immunosorbant assays (ELISAs) are the bases of many of the commercial kits currently available in chemist shops. The assay depends on the double reaction of standard phase antibody with enzyme labelled antibody, which is sensitive and s...
متن کاملTalking on the Moon
How effective, efficient and natural human-robot interaction can be depends for an important part on how meaning can be shared and construed between a human and a robot. The paper presents an initial investigation in the architectural functions that appear to underly embodied, situated understanding in joint action and interaction. The identified functions are combined into a concept system arc...
