Questo è un problema classico per i ferrovieri, presentato per mostrare [...]
Random projections with tensors.Randomized Interpolative Decomposition of Separated Representations by David J. Biagioni, Daniel Beylkin, Gregory BeylkinWe introduce tensor Interpolative Decomposition (tensor ID) for the reduction of the separation rank of Canonical Tensor Decompositions (CTDs). Tensor ID selects, for a user-defined accuracy \epsilon, a near optimal subset of terms of a CTD to represent the remaining terms via a linear combination of the selected terms. Tensor ID can be used as
It used to be the case, 10 or so years ago, that William Stein maintained a website with extensive tables of -expansions of modular forms, computed using magma. However, as the edifice of civilization begins to crumble, this website no … Continue reading →
There is now a I can be an engineer Barbie. That sounds good! It's not. Imagine how this could be turned around and made sexist. What you are imagining might not be as bad as the reality. Depends on your imagination.
Guest Blogger Brittany Terese Fasy explains:
Remember the controversy over the Barbie doll that said
"Math class is tough!"? Well, Barbie strikes again.
If you haven't heard about II can be a computer engineer it is a story about how Barbie, as a "computer engineer" […]
