Sparse Autoencoders for Interpretable Out-of-Distribution Detection

Ayush Karmacharya, Luke Luschwitz, Lucia Romero, Yanan Niu, Joseph Campbell

Reliable detection of out-of-distribution (OOD) samples is crucial for the safe deployment of machine learning models. Neural networks often produce overconfident predictions for inputs that deviate from their training data, leading to significant degradation in performance. Whil…

PoseShield: Neural Collision Fields for Human Self-Collision Resolution

Zhengyuan Li, Zeyun Deng, Yifan Shen, Liangyan Gui, Miaolan Xie, Joseph Campbell, et al.

Self-collision remains a persistent challenge in SMPL-based human pose estimation and motion generation. Under extreme articulations or stochastic motion synthesis, generated meshes frequently exhibit self-penetrations, leading to physically implausible results. We propose PoseSh…
