In wireless sensor networks, the limited power source makes sensing expensive. It is thus a big optimization problem that obtaining more and useful information but making less observations. In this paper, we compare two model based approaches. One is to apply the improved VoIDP algorithm on a chain graphical model for selecting a subset of observations that minimizes the overall uncertainty; The other is to find a selection of observations on a Gaussian process model that maximizes the entropy and the mutual information criteria respectively. We compare the selections based on their prediction accuracies for the temporal observations on a...
