Seulki Park, Youren Zhang, Stella X. Yu, Sara Beery, Jonathan Huang

ICLR 2025poster

Hierarchical classification predicts labels across multiple levels of a taxonomy, e.g., from coarse-level \textit{Bird} to mid-level \textit{Hummingbird} to fine-level \textit{Green hermit}, allowing flexible recognition under varying visual conditions. It is commonly framed as multiple single-leve…

Unsupervised Feature Learning with Emergent Data-Driven Prototypicality

Yunhui Guo, Youren Zhang, Yubei Chen, Stella X. Yu

CVPR 2024poster

Given a set of images our goal is to map each image to a point in a feature space such that not only point proximity indicates visual similarity but where it is located directly encodes how prototypical the image is according to the dataset. Our key insight is to perform unsupervised feature learnin…
