OCReP: An Optimally Conditioned Regularization for Pseudoinversion Based Neural Training

, 2015
In this paper we consider the training of single hidden layer neural networks by pseudoinversion, which, in spite of its popularity, is sometimes affected by numerical instability issues.

Selection of tuning parameters in bridge regression models via Bayesian information criterion

, 2012
We consider the bridge linear regression modeling, which can produce a sparse or non-sparse model. A crucial point in the model building process is the selection of adjusted parameters including a regularization parameter and a tuning parameter in bridge

Genetic parameters, character association and path analysis for fruit yield and its component characters in guava (Psidium guajava L.)

Electronic Journal of Plant Breeding, 2019
The present investigation was conducted to estimate genetic parameters, correlations and path coefficients from different traits of nine genotypes in guava. The genotypes exhibited a wide range of variability for all the characters studied.

The J1-J2 model: First order phase transition versus deconfinement of spinons

, 2006
We revisit the phase transition from the N\'eel ordered to a valence bond solid (VBS) state in the two-dimensional $J_1-J_2$ antiferromagnetic Heisenberg model.

Associated production in K+p interactions at 3.5 GcV/c

Nuclear Physics B, 1970
Abstract In a recently completed experiment using 3.54 GeV/c K+ mesons in the BNL 80-inch chamber, we have investigated the two-prong plus one or two VO topology for events with associated production. We find no evidence for any production of any hypercharge 2 states.

RR Lyrae Stars In The GCVS Observed By The Qatar Exoplanet Survey

, 2014
We used the light curve archive of the Qatar Exoplanet Survey (QES) to investigate the RR Lyrae variable stars listed in the General Catalogue of Variable Stars (GCVS). Of 588 variables studied, we reclassify 14 as eclipsing binaries, one as an RS Canum Venaticorum-type variable, one as an irregular variable, four as classical Cepheids, and one as a ...
