Hashing is at the heart of large-scale image similarity search, and recent methods have been substantially improved through deep learning techniques.

Binarization Deep Hashing +3

A spectral least-squares-type method for heavy-tailed corrupted regression with unknown covariance \& heterogeneous noise

no code implementations6 Sep 2022 Roberto I. Oliveira, Zoraida F. Rico, Philip Thompson

We wish to estimate a $p$-dimensional parameter $b^*$ given such sample of a label-feature pair $(y, x)$ satisfying $y=\langle x, b^*\rangle+\xi$ with heavy-tailed $(x,\xi)$.
