Machine learning for multivariate data through the Riemannian geometry of positive definite matrices in Python ...

Abstract: A noise covariance matrix estimation approach in unknown noise field for direction finding applicable for the practically important cases of nonuniform and block-diagonal sensor noise is ...

Our method involves reconstructing the covariance matrix using the proposed CNN model, which is trained with covariance matrices from the actual received signals to their corresponding covariance ...

Commissions do not affect our editors' opinions or evaluations. Inverse ETFs aim for performance that is the mirror-image opposite of their target, customarily an index. Their investments are ...

This valuable study shows a surprising scale-invariance of the covariance spectrum of large-scale recordings in the zebrafish brain in vivo. A solid analysis demonstrates that a Euclidean random ...
