The matrix I VA-U is often called the capacitance matrix. Suppose that U is n x m with columns u, u, .-., u,,, and V is m x n with rows v, v, ..., v,. From the (1) identity UV= Y u;v;, i=1 we see that (1) provi

CORAL applies a transformation ϕ that re-colors the whitened features of the samples in S with the covariance matrix estimated from the feature distribution of the samples in T; the model is learned on the transformed data. Because estimating such covariance matrix does not require information ...

The fundamental problem is to solve an inverse problem to obtain the model parameters of a structure based on measured response datasets. In this respect, it is essential to recognise that the measured responses can only be obtained at limited degrees of freedom (DOF). Furthermore, the finite ...
