A simulation study for the analysis of uncertain binary responses: Application to first insemination success in beef cattle

open access: yesGenetics Selection Evolution, 2005
A simulation was carried out to investigate the methods of analyzing uncertain binary responses for success or failure at first insemination. A linear mixed model that included, herd, year, and month of mating as fixed effects; and unrelated service sire,

Sparse logistic principal components analysis for binary data [PDF]

open access: yes, 2010
We develop a new principal components analysis (PCA) type dimension reduction method for binary data. Different from the standard PCA which is defined on the observed data, the proposed PCA is defined on the logit transform of the success probabilities ...

An Algorithm for Data Hiding in Binary Images [PDF]

open access: yesAl-Rafidain Journal of Computer Sciences and Mathematics, 2008
In this work a new data hiding algorithm for binary images is used. In this algorithm the pixels which can be flipped without introducing noticeable artifacts are identified at first by using some rules that examine the neighbors of the central pixels in

New RR Lyrae variables in binary systems [PDF]

open access: yes, 2015
Despite their importance, very few RR Lyrae (RRL) stars have been known to reside in binary systems. We report on a search for binary RRL in the OGLE-III Galactic bulge data.

A high performance k-NN approach using binary neural networks [PDF]

open access: yes, 2004
This paper evaluates a novel k-nearest neighbour (k-NN) classifier built from binary neural networks. The binary neural approach uses robust encoding to map standard ordinal, categorical and numeric data sets onto a binary neural network.

IMNM: integrated multi-network model for identifying pepper leaf diseases

open access: yesFrontiers in Plant Science
As a vegetable crop with high economic value, the yield of pepper is often significantly restricted by leaf diseases, and the spots formed by these diseases on the surface of leaves are highly complex in color and texture characteristics. To overcome the
