the phrase "direct product" is used. When the index set is infinite, the direct sum is not the same as the direct product. In the direct sum, all but finitely many coordinates must be zero. https://en.wikipedia.org/wiki/Matrix_addition In general, the direct sum ofnmatrices is:[2]...

5.4.1 Estimation of the data covariance matrix The covariance matrix is a symmetric matrix whose entries represent the variance between all elements of a data set, whereby elements we may interchangeably refer to the features of the data set or the examples, themselves. For example, if we assum...
An embedding matrix in deep learning refers to a matrix used to map each word in the training data to a word-embedding vector, allowing for a lower-dimensional representation of the vocabulary. It is collaboratively optimized during the training process to improve the model's performance. AI gen...
Finally, the spatial covariance matrix of Zernike coefficients (Fig. 3d) can be acquired from: $$\left\langle a{a}^{{\mathrm{T}}}\right\rangle =\left\langle X\varphi {\varphi }^{{\mathrm{T}}}{X}^{{\mathrm{T}}}\right\rangle =X\left\langle \varphi {\varphi }^{{\mathrm{T}...
Specifically, nvidia-smi topo -mp generates a simple topology map in the form of a matrix showing the connection(s) at the intersection of the installed GPUs and network interfaces.For readability, the sample output below from a DGX-2 system shows the first eight columns, and the first four...
12), and the spread is related to uncertainties in the model-dependent nuclear matrix element calculation. The most direct way to assess the neutrino mass is via the kinematics of single-β decays or electron capture processes. This method is independent of any cosmological model and of the ...
