Selecting the optimal number of features in a classifier ensemble normally requires a validation set or cross-validation techniques. In this paper, feature ranking is combined with...
This paper presents a novel low power and high performance analog front end circuit for passive RFID transponder. With a novel architecture including three rectifier circuits, amo...
In this paper, we outline a framework for appropriate and proper usage of simulated data for biometric authentication. Currently, there are no formal guidelines concerning the use...
