Why are projected variables in canonical correlation analysis uncorrelated?
Let $x\in R^d$ and $y\in R^e$ be two vectors with covariance and cross-covariance matrices
$S_{xx}, S_{yy}, S_{xy}, S_{yx}$. The canonical correlation analysis is based on the projection of $x$ onto ...

Are we missing correlation to achieve a artificial intelligence comparable to humans?
I don't think neural networks are enough to copy human intelligence because in the end a machine only using a neural network to decide on something still is unable to recognize patterns.
So I was ...

What is meant by correlation structure?
I know only about the Pearson's correlation coefficient in literature.
Covariance between two random variables $X$ and $Y$ is defined as
$$Cov[X, Y] = \mathbb{E}[(X - \mathbb{E}[X])(Y-\mathbb{E}[Y])]$$...
