Then, given two bases of a vector space, there is a way to translate vectors in terms of one basis into terms of the other; this is known as change of basis. Change of basis is a technique applied to finite-dimensional vector spaces in order to rewrite vectors in terms of a different set of basis elements. It is useful for many types of matrix.

However, if they are units of voltage, then you will multiply by 10. Furthermore, for power, SNR 20 log (S &247; N) and for voltage, SNR 10 log (S &247; N).

At least one point in each class is necessary to learn an SVM model. Adjust the regularization parameter (nu) between 0 and 1. Small values correspond to a hard margin, i.e. low tolerance towards misclassified data and may lead to overfitting of noisy data. Large values correspond to a soft margin and may ignore features in the data.

In the same way, the two matrices must have the same dimension i.e. the same number of rows and the same number of columns.
