Clustering: which correlated feature to eliminate

I am trying to perform a simple k-means clustering of a sample population based on about 30 features. Some of the variables are highly correlated as measured by the Pearson correlation coefficient and ...

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 $$Cov[X, Y] = \mathbb{E}[(X - \mathbb{E}[X])(Y-\mathbb{E}[Y])]$$...
