Discriminant analysis of colour measurements reveals allele dosage effect of ASIP/MC1R in bay horses
horse coat colour ASIP MC1R CIE L*a*b
2018/11/23
Considering the variability of bay coat colour, we aimed to investigate the association of different shades of bay with ASIP and MC1R genotype combinations and we studied the discrimination between th...
Discriminant Adaptive Nearest Neighbor Classification
lassification nearest neighbors linear discriminant an,alysis,curse of dimensionality
2015/8/21
earest neighbor classification expects the class conditional probabilities to be locally constant,and suffers from bias in high dimensions. We propose a locally adaptive form of nearest neighbor class...
Functional Linear Discriminant Analysis for Irregularly Sampled Curves
Classification Filtering Functional data Linear discriminant analysis Low dimensional representation Reduced rank Regularized discriminant analysis Sparse curves
2015/8/21
We introduce a technique for extending the classical method of Linear Discriminant Analysis to data sets where the predictor variables are curves or functions. This procedure, which we call functional...

Regularized linear discriminant analysis microarrays
2015/8/21
In this paper, we introduce a modified version of linear discriminant analysis, called the “shrunken centroids regularized discriminant analysis” (SCRDA). This method generalizes the idea of the “near...
We consider the problem of performing interpretable classification in the high-dimensional setting, in which the number of features is very large and the number of observations is limited. This settin...
Prime Decomposition in Iterated Towers and Discriminant Formulae

2014/4/28
Dimensionality reduction algorithms, which aim to select a small set of efficient and discriminant features, have attracted great attention for Hyperspectral Image Classification. The manifold learnin...
Multi-quadratic quad equations: integrable cases from a factorised-discriminant hypothesis
Multi-quadratic quad equations integrable cases factorised-discriminant hypothesis Exactly Solvable and Integrable Systems
2012/4/26
We give integrable quad equations which are multi-quadratic (degree-two) counterparts of the well-known multi-affine (degree-one) equations classified by Adler, Bobenko and Suris (ABS). These multi-qu...
