Poisson Learning: Graph Based Semi-Supervised Learning At Very Low Label Rates

1 code implementation ICML 2020 Jeff Calder, Brendan Cook, Matthew Thorpe, Dejan Slepcev

We propose a new framework, called Poisson learning, for graph based semi-supervised learning at very low label rates.

Properly-weighted graph Laplacian for semi-supervised learning

no code implementations10 Oct 2018 Jeff Calder, Dejan Slepcev

The performance of traditional graph Laplacian methods for semi-supervised learning degrades substantially as the ratio of labeled to unlabeled data decreases, due to a degeneracy in the graph Laplacian.

Error estimates for spectral convergence of the graph Laplacian on random geometric graphs towards the Laplace--Beltrami operator

no code implementations30 Jan 2018 Nicolas Garcia Trillos, Moritz Gerlach, Matthias Hein, Dejan Slepcev

sample from a $m$-dimensional submanifold $M$ in $R^d$ as the sample size $n$ increases and the neighborhood size $h$ tends to zero.
