Despite being separated by millions of years of evolution, dogs and cats have evolved similar skull shapes due to ...

Researchers in China have achieved a major leap in quantum photonics by generating a massive 60-mode entangled cluster state ...

In particular, they used a "covariance matrix" to flesh out patterns within the data using a statistical technique called principal-component analysis (PCA). PCA is a widely used technique to ...

"Because the thing you are estimating is much, much smaller than the entire covariance matrix, you can do it much, much faster," Sridhar explains. This means that one can scale up to much larger ...

The technique extracts cross-diagonal elements from the covariance matrix to form Toeplitz matrices, then averages them using a counting matrix to effectively decorrelate signals. This provides more ...

We first analyze how the cross-covariance matrix and the number of measurements in centralized CL systems, based on extended Kalman filter (EKF), impact positioning accuracy. Our theoretical analysis ...

Flat prior (not usually recommended); Super-vague but proper prior: normal(0, 1e6) (not usually recommended); Weakly informative prior, very weak: normal(0, 10); Generic weakly informative prior: ...

Laurence Fishburne is not sure if he will ever reprise his role of Morpheus in The Matrix universe. The actor appeared on The View and said the team “didn’t respond well” after he pitched ...
