Learning Prototype Classifiers for Long-Tailed Recognition

IJCAI 2023poster

The problem of long-tailed recognition (LTR) has received attention in recent years due to the fundamental power-law distribution of objects in the real-world. Most recent works in LTR use softmax classifiers that are biased in that they correlate classifier norm with the amount of training data for…

F-VAEGAN-D2: A Feature Generating Framework for Any-Shot Learning

CVPR 2019poster

When labeled training data is scarce, a promising data augmentation approach is to generate visual features of unknown classes using their attributes. To learn the class conditional distribution of CNN features, these models rely on pairs of image features and class attributes. Hence, they can not m…

Monocular 3D Human Pose Estimation by Generation and Ordinal Ranking

ICCV 2019poster

Monocular 3D human-pose estimation from static images is a challenging problem, due to the curse of dimensionality and the ill-posed nature of lifting 2D-to-3D. In this paper, we propose a Deep Conditional Variational Autoencoder based model that synthesizes diverse anatomically plausible 3D-pose sa…
