How to keep the probability of hand-off drops within a prespecified limit is a very important Quality-of-Service (QoS) issue in cellular networks because mobile users should be abl...
We present a model-free reinforcement learning method for partially observable Markov decision problems. Our method estimates a likelihood gradient by sampling directly in paramet...
We address several challenges for applying statistical dialog managers based on Partially Observable Markov Models to real world problems: to deal with large numbers of concepts, ...
