Fusion of the information provided by distributed sensors is important in the future pervasive computing systems. The objective of this paper is to quantify the relative amount of information delivered by individual sensors in a distributed sensor system. To formalize our approach, we consider the problem of fusing the statistical information obtained using low-rate sensor recordings viðnÞ in o...

All mobile bases suffer from localization errors. Previous approaches to accommodate for localization errors either use external sensors such as lasers or sonars, or use internal sensors like encoders. An encoder’s information is integrated to derive the robot’s position; this is called odometry. A combination of external and internal sensors will ultimately solve the localization error problem...

Previously proposed measures of entanglement, such as entanglement of formation and assistance, are shown to be special cases of the relative entropy of entanglement. The difference between these measures for an ensemble of mixed states is shown to depend on the availability of classical information about particular members of the ensemble. Based on this, relations between relative entropy of e...
