Approximate Planning in POMDPs with Macro-Actions
Recent research has demonstrated that useful POMDP solutions do not require consideration of the entire belief space. We extend this idea with the notion of temporal abstraction. ...

Influence of Leakage Reduction Techniques on Delay/Leakage Uncertainty
One of the main challenges for design in the presence of process variations is to cope with the uncertainties in delay and leakage power. In this paper, the influence of leakage r...
