We propose a sketch-based sampling algorithm, which effectively exploits the data sparsity. Sampling methods have become popular in large-scale data mining and information retrieval, where high data s...
L1-regularization path algorithm for generalized linear models
Generalized linear model Lasso Path algorithm Predictor–corrector method Regularization Variable selection
2015/8/21
We introduce a path following algorithm for L1-regularized generalized linear models. The L 1-regularization procedure is useful especially because it, in effect, selects variables according to the am...
Presence-Only Data and the EM Algorithm
Boosted trees EM algorithm Logistic model Presence-only data Use-availability data
2015/8/21
In ecological modeling of the habitat of a species, it can be prohibitively expensive to determine species absence.Presence-only data consist of a sample of locations with observed presences and a sep...
A new algorithm for computing the multivariate Faà di Bruno's formula
algorithm computing multivariate Faà di Bruno's formula
2011/1/4
A new algorithm for computing the multivariate Fa\`a di Bruno's formula is provided. We use a symbolic approach based on the classical umbral calculus that turns the computation of the multivariate Fa...
Construction of the Normal Form for Elliptic Tori in Planetary Systems. Part I: Numerical Validation of the Semi-Analytic Algorithm

2010/11/10
We adapt the Kolmogorov's normalization algorithm (which is the key element of the original proof scheme of the KAM theorem) to the construction of a suitable normal form related to an invariant ellip...
A Comparison of the Performances between a Genetic Algorithm and the Taguchi Method over Artificial Problems
Genetic algorithm Experimental design Taguchi method
2009/10/13
In the manufacturing industry, to produce the best quality product, it is important to de ne several levels of inputs. The Taguchi method is proposed for the solution of this problem and is widely use...
