ALLUDE: A Unified Evaluation System for Configurable Attacks in Differentiable Environments

Mansi Phute, Alexander Greenhalgh, Matthew Hull, Haoran Wang, Alec Helbling, ShengYun Peng, et al.

Adversarial attacks against vision models like object detectors are often evaluated under limited conditions, leaving their performance under-characterized. Bridging simulation and differentiable rendering enables more robust, end-to-end evaluation of these adversarial attacks, y…

Dimensionality Reduction Meets Network Science: Sensemaking on UMAP's kNN Graph

Duen Horng Chau, Donghao Ren, Fred Hohman, Dominik Moritz

While UMAP is widely used for exploring high-dimensional data, typical workflows focus on its lower-dimensional embedding, largely overlooking the rich k-nearest-neighbor (kNN) graph that UMAP constructs internally. This graph encodes the data manifold in its original high-dimens…
