Helping robots handle uncertainty
Boston MA (SPX) Jun 05, 2015
Decentralized partially observable Markov decision processes are a way to model autonomous robots' behavior in circumstances where neither their communication with each other nor their judgments about the outside world are perfect. The problem with Dec-POMDPs (as they're abbreviated) is that they're as complicated as their name. They provide the most rigorous mathematical models of multiagent systems - not just robots, but any autonomous networked devices --under uncertainty. But for all but the s ... read more
