NettetLinear discriminant analysis (LDA) has been a popular method for dimensionality reduction, which preserves class separability. The projection vectors are commonly … NettetThe purpose of discriminant analysis is to find the linear combination of ratios which best discriminates between the groups which are being classified. The methodology is too complex for detailed discussion here.2 ... cation," Journal of the Royal Statistical Society, Series B (1948), pp. 159-93.

NettetRecently, Xu et al. suggested modified linear discriminant analysis (MLDA). This method is based on the shrink type estimator of the covariance matrix derived by Ledoit and Wolf. This estimator was proposed under the asymptotic framework A0:n = O(p) A 0: n = O ( p) and p =O(n) p = O ( n) when p → ∞ p → ∞. In this paper, we propose a ... NettetFriedman, J. (1989).

NettetLinear discriminant analysis (LDA) is a simple classification method, mathematically robust, and often produces robust models, whose accuracy is as good as more complex methods. LDA assumes that the various classes collecting similar objects (from a given area) are described by multivariate normal distributions having the same covariance but … NettetSeLDA stands for Semi-parametric linear discriminant analysis, which is introduced in Section2.2.4.
