First, we compute each group mean on Xd1 and Xd2, respectively; with equal-size groups these means, of course, sum to zero, within rounding error. Then we find the matrix of within-group deviations and the matrix of among-group deviations from group and grand mean, respectively. TABLE ...
Fisher discriminant function can reach the maximum;(2)When the popular scatter matrix is singular, it is possible that there exists one discriminant vector on which the between\\|class distance of the projected set of the training sample set is equal to zero, which is meaningless for ...
For contradiction, suppose that there exist some constants l_1,c_i\in\mathbb{F}_p that are not equal to zero simultaneously such that $$\sum_{k=1}^sc_kq_k+l_1\xi_1=0\tag{6}$$ Left multiplying both sides of Eq. (6) by \psi(A) gives $$\sum^s_{k=1}c_k\psi(A)q_k...
when the discriminant value is positive, we get two real solutions when the discriminant value is zero, we get one real solution when the discriminant value is negative, we get a pair of complex solutions standard form the standard discriminant form for the quadratic equation ax 2 + bx + c...
The meaning of DISCRIMINANT is a mathematical expression providing a criterion for the behavior of another more complicated expression, relation, or set of relations.
Spectral Regression Discriminant Analysis (SRDA) was proposed as an extension to LDA based on the spectral regression [29]. It has been shown that in the case of LDA the matrix J (35) has C eigenvectors corresponding to nonzero values, all of which correspond to the eigenvalue of 1 and ...
When a, b, and c are real numbers, a ≠ 0 and the discriminant is zero, then the roots α and β of the quadratic equation ax2+ bx + c = 0 are real and equal.Case III: b2–4ac < 0 When a, b, and c are real numbers, a ≠ 0 and the discriminant is negative, then the...
weighted by sample size. Using matrix multiplication, vectors of differences in group means are multiplied by the inverse of the VCM to combine and scale all differences into one number, theMahalanobis distance. If allMahalanobis distancesare significantly greater than zero, then the distances reflect...
This is translated as an objective function (also called cost or loss function) that quantifies how good/bad a set of parameters are compared with others. The objective function can then be used to train our model and find the optimal parameters. Once a model is fitted...
