A formula for the area of a triangle: Useless, but explicitly in Deep Sets form arXiv:2503.22786v1 Announce Type: cross Abstract: Any permutation-invariant function of data points $vec{r}_i$ can be written in the form $rho(sum_iphi(vec{r}_i))$ for suitable functions $rho$ and $phi$. This form – known in the machine-learning literature as Deep Sets – also generates a…
