| Feb 13, 2019 at 13:39 | comment | added | Denis Kolesnikov | If I find the family distribution described above, I can model the noises in tensor elements by proper choice of noise for Tucker core and factors. If such a family doesn't exist, my only hope is that the central limit theorem guarantees that independently distributed noises in tensor decomposition factors cause the Gaussian noises on the tensor elements. | |
| Feb 13, 2019 at 13:38 | comment | added | Denis Kolesnikov | Formally it satisfies the conditions, but I want to find distributions with non-zero dispersion. My problem originates from tensor decomposition issue. Let us consider the Tucker decomposition for example - what is the connection between noises in Tucker core and factors and noises in tensor elements? en.wikipedia.org/wiki/Tucker_decomposition | |
