Zero-Shot Visual Recognition via Bidirectional Latent Embedding

no code implementations7 Jul 2016 Qian Wang, Ke Chen

In the top-down stage, semantic representations of unseen-class labels in a given label vocabulary are then embedded to the same latent space to preserve the semantic relatedness between all different classes via our proposed semi-supervised Sammon mapping with the guidance of landmarks.

Attentional Neural Network: Feature Selection Using Cognitive Feedback

1 code implementation NeurIPS 2014 Qian Wang, Jiaxing Zhang, Sen Song, Zheng Zhang

Attentional Neural Network is a new framework that integrates top-down cognitive bias and bottom-up feature extraction in one coherent architecture.

Groupwise Registration via Graph Shrinkage on the Image Manifold

no code implementations CVPR 2013 Shihui Ying, Guorong Wu, Qian Wang, Dinggang Shen

Specifically, we first use a graph to model the distribution of all image data sitting on the image manifold, with each node representing an image and each edge representing the geodesic pathway between two nodes (or images).
