Enhancing Tail Performance in Extreme Classifiers by Label Variance Reduction

ICLR 2024poster

Extreme Classification (XC) architectures, which utilize a massive One-vs-All (OvA) classifier layer at the output, have demonstrated remarkable performance on problems with large label sets. Nonetheless, these architectures falter on tail labels with few representative samples. This phenomenon has…

Unsupervised Clustering using Pseudo-semi-supervised Learning

ICLR 2020poster

In this paper, we propose a framework that leverages semi-supervised models to improve unsupervised clustering performance. To leverage semi-supervised models, we first need to automatically generate labels, called pseudo-labels. We find that prior approaches for generating pseudo-labels hurt cluste…
