Atomic Decomposition by Basis Pursuit
Articolo
Articolo
Scott Shaobing Chen; David L. Donoho; Michael A. Saunders · SIAM Journal on Scientific Computing · 1998
The time-frequency and time-scale communities have recently developed a large number of overcomplete waveform dictionaries --- stationary wavelets, wavelet packets, cosine packets, chirplets, and warplets, to name a few....

Convergence Properties of the Nelder--Mead Simplex Method in Low Dimensions
Articolo
Articolo
Jeffrey C. Lagarias; James A. Reeds; Margaret H. Wright; Paul E. Wright · SIAM Journal on Optimization · 1998
Abstract. The Nelder–Mead simplex algorithm, first published in 1965, is an enormously popular direct search method for multidimensional unconstrained minimization. Despite its widespread use, essentially no theoretica...

The random subspace method for constructing decision forests
Articolo
Articolo
Tin Kam Ho · IEEE Transactions on Pattern Analysis and Machine Intelligence · 1998
Much of previous attention on decision trees focuses on the splitting criteria and optimization of tree sizes. The dilemma between overfitting and achieving maximum accuracy is seldom resolved. A method to construct a de...

General Methods for Monitoring Convergence of Iterative Simulations
Articolo
Articolo
Stephen P. Brooks; Andrew Gelman · Journal of Computational and Graphical Statistics · 1998
Abstract We generalize the method proposed by Gelman and Rubin (1992a) for monitoring the convergence of iterative simulations by comparing between and within variances of multiple chains, in order to obtain a family of ...

A study of alternative selection mechanisms for multiple cossover per couple in genetic algorithms
Testo / risorsa
Testo / risorsa
Esquivel, Susana Cecilia et al · SEDICI UNLP · 1998
Multiple crossover per couple (MCPC) is a newly introduced crossover method which in contrast with the single crossover per couple approach (SCPC), permits more than one crossover operation for each mating pair. MCPC was...

Parallel ant system applied to the multiple knapsack problem
Testo / risorsa
Testo / risorsa
Cena, Marcelo Guillermo et al · SEDICI UNLP · 1998
Interesting real world combinatorial problems are NP-complete and many of them are hard to solve by using traditional methods. However, several heuristic methods have been developed in order to obtain timely suboptimal s...

Self-adaptation of parameters for MCPC in genetic algorithms
Testo / risorsa
Testo / risorsa
Esquivel, Susana Cecilia et al · SEDICI UNLP · 1998
As a new promising crossover method, multiple crossovers per couple (MCPC) deserves special attention in evolutionary computing field. Allowing multiple crossovers per couple on a selected pair of parents provided an ext...

Automated docking using a Lamarckian genetic algorithm and an empirical binding free energy function
Articolo
Articolo
Garrett M. Morris; David S. Goodsell; Robert S. Halliday; Ruth Huey; William E. Hart; Richard K. Belew; Arthur J. Olson · Journal of Computational Chemistry · 1998
A novel and robust automated docking method that predicts the bound conformations of flexible ligands to macromolecular targets has been developed and tested, in combination with a new scoring function that estimates the...
