Example text

Sw calculates the amount of variance between the samples in each class. N represents the sample vectors xi with n dimensionality and Si is the sum of the covariance matrix of the samples in each class. Si is calculated by using the Eq. 10) x Si represents the class dependent scatter matrix. Xi represents the data matrix corresponding to class i. Ni represents the sample vectors present in class i. c represents the total number of classes. The between class scatter matrix is given by the Eq. 12) i=1 The overall or mixing scattering matrix is calculated by the covariance matrix of all speech samples as shown in Eq.

9) i=1 Within class scatter matrix is given by Eq. 9. Sw calculates the amount of variance between the samples in each class. N represents the sample vectors xi with n dimensionality and Si is the sum of the covariance matrix of the samples in each class. Si is calculated by using the Eq. 10) x Si represents the class dependent scatter matrix. Xi represents the data matrix corresponding to class i. Ni represents the sample vectors present in class i. c represents the total number of classes. The between class scatter matrix is given by the Eq.

20) Or, for each column vector Wi of W. 21) One method for solving this eigen problem is to take the inverse of Sw and solve the following problem by using matrix Sw−1 Sb . 22) For W we must calculate the eigenvalues values and eigenvectors by using the singular value decomposition of Sw−1 Sb . This algorithm is optimal only when the scatter matrix is non singular. If Sw is singular then we get a warning that matrix is close to singular or badly scaled. This is a singularity problem and occurs due to high dimensional and low sample size speech data.
