Deep Reinforcement Learning with Double Q-Learning
Article
Article
Hado van Hasselt; Arthur Guez; David Silver · OpenAlex · 2016
The popular Q-learning algorithm is known to overestimate action values under certain conditions. It was not previously known whether, in practice, such overestimations are common, whether they harm performance, and whet...

Image Denoising by Sparse 3-D Transform-Domain Collaborative Filtering
Article
Article
Kostadin Dabov; Alessandro Foi; Vladimir Katkovnik; Karen Egiazarian · IEEE Transactions on Image Processing · 2007
We propose a novel image denoising strategy based on an enhanced sparse representation in transform domain. The enhancement of the sparsity is achieved by grouping similar 2-D image fragments (e.g., blocks) into 3-D data...

LINCS: A linear constraint solver for molecular simulations
Article
Article
Berk Hess; Henk Bekker; Herman J. C. Berendsen; J. G. E. M. Fraaije · Journal of Computational Chemistry · 1997
In this article, we present a new LINear Constraint Solver (LINCS) for molecular simulations with bond constraints. The algorithm is inherently stable, as the constraints themselves are reset instead of derivatives of th...

No free lunch theorems for optimization
Article
Article
David H. Wolpert; William G. Macready · IEEE Transactions on Evolutionary Computation · 1997
A framework is developed to explore the connection between effective optimization algorithms and the problems they are solving. A number of "no free lunch" (NFL) theorems are presented which establish that for any algori...

Novel approach to nonlinear/non-Gaussian Bayesian state estimation
Article
Article
Neil Gordon; David Salmond; A. F. M. Smith · IEE Proceedings F Radar and Signal Processing · 1993
An algorithm, the bootstrap filter, is proposed for implementing recursive Bayesian filters. The required density of the state vector is represented as a set of random samples, which are updated and propagated by the alg...

Regularization and Variable Selection Via the Elastic Net
Article
Article
Hui Zou; Trevor Hastie · Journal of the Royal Statistical Society Series B (Statistical Methodology) · 2005
Summary We propose the elastic net, a new regularization and variable selection method. Real world data and a simulation study show that the elastic net often outperforms the lasso, while enjoying a similar sparsity of r...
