Fast informed bound
Did you know?
WebAlso introduced is a new method for computing an initial upper bound – the fast informed bound method. This method is able to improve significantly on the standard and commonly used upper bound computed by the MDP-based method. The quality of resulting bounds are tested on a maze navigation problem with 20 states, 6 actions and 8 observations. WebFIB (Fast Informed Bound) [3], do not plan in the space of beliefs, but plan over the state space. Consequently, these algorithms require much less memory and computation than belief-space planners, and have been widely used in robot control and manipulation [6], [7], [8], even if they are not able to represent optimal policies.
Weband the fast informed bound, together with empirical results, are discussed by M. Hauskrecht, “Value-Function Approximations for Partially Observable Markov DecisionProcesses,”JournalofAr-tiicialIntelligenceResearch,vol.13, pp.33–94,2000. WebExperimental results show that methods that preserve the shape of the value function over updates, such as the newly designed incremental linear vector and fast informed bound …
WebJan 1, 2015 · Two popular approximations for solving POMDPs are Q MDP [35] and fast informed bound (FIB) [34]. Q MDP has been used successfully in practice [36] ... WebNov 18, 2024 · The upper bound comes from the fast informed bound and the lower bound comes from point-based value iteration." However, in the code that comes after that statement, it appears to try and use FIB as the lower bound and PBVI as the upper bound.
