Extended Forward-Backward Algorithm
Journal of Mathematical Analysis and Applications, 2013 We propose an extended forward-backward algorithm for approximating a zero of a maximal monotone operator which can be split as the extended sum of two maximal monotone operators.

Backwards State-space Reduction for Planning in Dynamic Knowledge Bases [PDF]
Electronic Proceedings in Theoretical Computer Science, 2014 In this paper we address the problem of planning in rich domains, where knowledge representation is a key aspect for managing the complexity and size of the planning domain.

A forward-backward single-source shortest paths algorithm [PDF]
SIAM Journal on Computing, 2014 We describe a new forward-backward variant of Dijkstra's and Spira's Single-Source Shortest Paths (SSSP) algorithms. While essentially all SSSP algorithm only scan edges forward, the new algorithm scans some edges backward. The new algorithm assumes that

A forward--backward stochastic algorithm for quasi-linear PDEs [PDF]
The Annals of Applied Probability, 2006 We propose a time-space discretization scheme for quasi-linear parabolic PDEs. The algorithm relies on the theory of fully coupled forward--backward SDEs, which provides an efficient probabilistic representation of this type of equation.

Iterative Forward-Backward Pursuit Algorithm for Compressed Sensing [PDF]
Journal of Electrical and Computer Engineering, 2016 It has been shown that iterative reweighted strategies will often improve the performance of many sparse reconstruction algorithms. Iterative Framework for Sparse Reconstruction Algorithms (IFSRA) is a recently proposed method which iteratively enhances ...

Perceived severity of forward versus backward balance disturbances during walking in young and older adults. [PDF]
PLoS ONEFalls, which often result from trips or slips, pose a major health concern, particularly among older adults. Experiencing falls or near-falls from balance disturbances can shape subsequent gait-related decisions, as individuals may avoid situations they ...

Fast iterative algorithms for birefringent filter design [PDF]
Applied Computing and Informatics, 2021 Fast iterative algorithms for designing birefringent filters with any specified spectral response are proposed. From the Jones formalism, we derive two polynomials representing the transmitted and rejected response of the filter, respectively.

Forward and Backward Bellman Equations Improve the Efficiency of the EM Algorithm for DEC-POMDP
Entropy, 2021 Decentralized partially observable Markov decision process (DEC-POMDP) models sequential decision making problems by a team of agents. Since the planning of DEC-POMDP can be interpreted as the maximum likelihood estimation for the latent variable model ...
