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 ...

A Generalization of Forward-backward Algorithm [PDF]
Transactions of the Japanese Society for Artificial Intelligence, 2009 Structured prediction has become very important in recent years. A simple but notable class of structured prediction is one for sequences, so-called sequential labeling. For sequential labeling, it is often required to take a summation over all the possible output sequences, when estimating the parameters of a probabilistic model for instance.

Accelerated and Inexact Forward-Backward Algorithms [PDF]
SIAM Journal on Optimization, 2013 We propose a convergence analysis of accelerated forward-backward splitting methods for composite function minimization, when the proximity operator is not available in closed form, and can only be computed up to a certain precision. We prove that the $1/k^2$ convergence rate for the function values can be achieved if the admissible errors are of a ...

A Forward-Backward Abstraction Refinement Algorithm [PDF]
, 2008 Abstraction refinement-based model checking has become a standard approach for efficiently verifying safety properties of hardware/software systems. Abstraction refinement algorithms can be guided by counterexamples generated from abstract transition systems or by fixpoints computed in abstract domains.

Bayesian Recurrent Units and the Forward-Backward Algorithm
Interspeech 2022, 2022 Using Bayes's theorem, we derive a unit-wise recurrence as well as a backward recursion similar to the forward-backward algorithm. The resulting Bayesian recurrent units can be integrated as recurrent neural networks within deep learning frameworks, while retaining a probabilistic interpretation from the direct correspondence with hidden Markov models.

Modified Inertial Forward–Backward Algorithm in Banach Spaces and Its Application
Mathematics, 2021 In this paper, we present a new modified inertial forward–backward algorithm for finding a common solution of the quasi-variational inclusion problem and the variational inequality problem in a q-uniformly smooth Banach space.

The forward–backward envelope for sampling with the overdamped Langevin algorithm
Statistics and Computing, 2023 AbstractIn this paper, we analyse a proximal method based on the idea of forward–backward splitting for sampling from distributions with densities that are not necessarily smooth. In particular, we study the non-asymptotic properties of the Euler–Maruyama discretization of the Langevin equation, where the forward–backward envelope is used to deal with ...
