Spectral Top-Down Recovery of Latent Tree Models

1 code implementation26 Feb 2021 Yariv Aizenbud, Ariel Jaffe, Meng Wang, Amber Hu, Noah Amsel, Boaz Nadler, Joseph T. Chang, Yuval Kluger

For large trees, a common approach, termed divide-and-conquer, is to recover the tree structure in two steps.

Spectral neighbor joining for reconstruction of latent tree models

3 code implementations28 Feb 2020 Ariel Jaffe, Noah Amsel, Yariv Aizenbud, Boaz Nadler, Joseph T. Chang, Yuval Kluger

A common assumption in multiple scientific applications is that the distribution of observed data can be modeled by a latent tree graphical model.

Unsupervised Ensemble Learning with Dependent Classifiers

no code implementations20 Oct 2015 Ariel Jaffe, Ethan Fetaya, Boaz Nadler, Tingting Jiang, Yuval Kluger

In unsupervised ensemble learning, one obtains predictions from multiple sources or classifiers, yet without knowing the reliability and expertise of each source, and with no labeled data to assess it.
