Machine learning-based tools to model and to remove the off-target effectPattern Analysis and Applications - Tập 20 - Trang 87-100 - 2015
Riwal Lefort, Ludovico Fusco, Olivier Pertz, François Fleuret
A RNA interference, also called a gene knockdown, is a biological technique
which consists of inhibiting a targeted gene in a cell. By doing so, one can
identify statistical dependencies between a gene and a cell phenotype. However,
during such a gene inhibition process, additional genes may also be modified.
This is called the “off-target effect”. The consequence is that there are some
additional... hiện toàn bộ
Fingerprint reference point identification based on chain encoded discrete curvature and bending energyPattern Analysis and Applications - Tập 20 - Trang 253-267 - 2016
Geevar C. Zacharias, Madhu S. Nair, P. Sojan Lal
Reference point identification is important in automatic fingerprint recognition
system as it can be used to align fingerprints in a correct orientation in spite
of the possibility of different transformations in fingerprint images. It is
also used in fingerprint classification, as it is desirable to classify
fingerprint images for forensic type applications which require the input image
to be ver... hiện toàn bộ
Classifying image texture with statistical landscape featuresPattern Analysis and Applications - Tập 8 - Trang 321-331 - 2005
Cun Lu Xu, Yan Qiu Chen
This paper proposes to use three-dimensional information derived from the graph
of an image function for texture description. The graph of an image function is
a rumpled surface appearing like a landscape. To characterize the texture
through this landscape, six novel texture feature curves based on the statistics
of the geometrical and topological properties of the solids shaped by the graph
and a... hiện toàn bộ
A multiple attributes convolution kernel with reproducing propertyPattern Analysis and Applications - Tập 20 - Trang 485-494 - 2015
Lixiang Xu, Xiu Chen, Xin Niu, Cheng Zhang, Bin Luo
Various kernel-based methods have been developed with great success in many
fields, but very little research has been published that is concerned with a
multiple attribute kernel in reproducing kernel Hilbert space (RKHS). In this
paper, we propose a novel elastic kernel called a multiple attribute convolution
kernel with reproducing property (MACKRP) and present improved classification
results ov... hiện toàn bộ
MLP Based Linear Fea ure Ex rac ion for Nonlinearly Separable DataPattern Analysis and Applications - Tập 4 - Trang 227-234 - 2001
A. Raudys, J. A. Long
A novel approach to linear feature extraction is presented. Most supervised
feature extraction algorithms use mean square error or other measures based on
the difference between expected and actual output values as a performance
criterion. The novel approach presented here uses data visualisation together
with an empirical classification error (percentage of cases classified
incorrectly) as perfor... hiện toàn bộ
Bayesian classification and unsupervised learning for isolating weeds in row cropsPattern Analysis and Applications - Tập 17 - Trang 401-414 - 2012
François-Michel De Rainville, Audrey Durand, Félix-Antoine Fortin, Kevin Tanguy, Xavier Maldague, Bernard Panneton, Marie-Josée Simard
This paper presents a weed/crop classification method using computer vision and
morphological analysis. Subsequent supervised and unsupervised learning methods
are applied to extract dominant morphological characteristics of weeds present
in corn and soybean fields. The novelty of the presented technique resides in
the feature extraction process that is based on spatial localization of
vegetation ... hiện toàn bộ
Transform Based Lossy Compression of Multispectral ImagesPattern Analysis and Applications - Tập 4 - Trang 39-50 - 2014
A. Kaarna, J. Parkkinen
We have composed compression methods, which are based on the one-, two- and
three-dimensional wavelet transforms. In addition, clustering the spectra of the
image is considered. These compression methods, combining compression in the
spectral and spatial domains, are compared by using a dataset of 65
multispectral images. The experimental results show that, at low compression
ratios, the best meth... hiện toàn bộ
Local support-based partition algorithm for frequent pattern miningPattern Analysis and Applications - Tập 22 - Trang 1137-1147 - 2018
Vijayakumar Kadappa, Shivaraju Nagesh
Frequent pattern (itemset) mining is one of the established approaches for
knowledge discovery. Minimizing the number of database scans (I/O overhead) is a
challenging task in Frequent itemset mining. Partition algorithm is one of the
early novel approaches to reduce the database I/O overhead as compared to
Apriori algorithm and other related methods. However, Partition algorithm
suffers from a si... hiện toàn bộ
