Feb 6, 2021 · I am not a mathematics student but somehow have to know about L1 and L2 norms. I am looking for some appropriate sources to learn these things and know they work and what are their differences. I am
eno1 is the onboard Ethernet (wired) adapter. lo is a loopback device. You can imagine it as a virtual network device that is on all systems, even if they aren't connected to any network. It has an IP address of 127.0.0.1 and can be used to access network services locally. For example, if you run a webserver on your machine and browse to it with Firefox or Chromium on …
May 16, 2013 · A lot of papers refer to it as a 'pseudo-norm' or 'quasi-norm' but they do not mean this in the standard mathematical sense, they just mean it is not a norm, and are being loose with terminology. The pseudonorm definition in Robert's answer is quite standard. The definition of quasinorm seems to be a bit less standard.
This definition of the '0-norm' isn't very useful because (1) it doesn't satisfy the properties of a norm and (2) $0^ {0}$ is conventionally defined to be 1.
I have long suspected that this practice of calling the cardinality function the '$\ell_0$ norm' would cause problems, and this post is evidence of that. The so-called '$\ell_0$ norm' is not a norm, and it is not convex. If Wikipedia is to be believed, the term '$\ell_0$ norm' was coined by David Donoho, in his work on using the $\ell_1$ norm (a true norm, and therefore convex) as a proxy for ...

I have no background in gradients. You are correct, the answer for L0-norm is discontinuous. And what is a coordinate? Can you point to me a link on all these?
