    Upper Bounds on Expected Hitting Times in Mostly-Covered Delay-Tolerant Networks

    The authors derive theoretical bounds on expected hitting times in densely covered Delay-Tolerant Networks (DTNs). They consider a number of fixed (data collector) nodes deployed in the DTN region, and a number of mobile (data generator) nodes that move freely in the region according to Brownian motion. As it moves,...

    Improving Policy Gradient Estimates With Influence Information

    In Reinforcement Learning (RL) it is often possible to obtain sound, but incomplete, information about influences and independencies among problem variables and rewards, even when an exact domain model is unknown. For example, such information can be computed based on a partial, qualitative domain model, or via domain-specific analysis techniques....
