In this paper we propose strategies for estimating performance of a classifier when labels cannot be obtained for the whole test set. The number of test instances which can be labeled is very small compared to the whole test data size. The goal then is to obtain a precise estimate of classifier performance using as little labeling resource as possible. Specifically, we try to answer, how to sel...

Several temporal planning systems (e.g. Allen & Koomen, Descartes , parcPLAN) divide the planning process into two distinct phases: action introduction and plan verification. This thesis develops a detailed model of these two phases and their “interface”, and shows how the model can be exploited to enhance the efficiency of plan generation. The main focus is on plan verification, and the contex...

In this paper we int...
