On Binary Embedding using Circulant Matrices

no code implementations20 Nov 2015 Felix X. Yu, Aditya Bhaskara, Sanjiv Kumar, Yunchao Gong, Shih-Fu Chang

To address this problem, we propose Circulant Binary Embedding (CBE) which generates binary codes by projecting the data with a circulant matrix.

Web Scale Photo Hash Clustering on A Single Machine

no code implementations CVPR 2015 Yunchao Gong, Marcin Pawlowski, Fei Yang, Louis Brandy, Lubomir Bourdev, Rob Fergus

In addition, we propose an online clustering method based on binary k-means that is capable of clustering large photo stream on a single machine, and show applications to spam detection and trending photo discovery.

Deep Convolutional Ranking for Multilabel Image Annotation

no code implementations17 Dec 2013 Yunchao Gong, Yangqing Jia, Thomas Leung, Alexander Toshev, Sergey Ioffe

Multilabel image annotation is one of the most important challenges in computer vision with many real-world applications.

Learning Binary Codes for High-Dimensional Data Using Bilinear Projections

no code implementations CVPR 2013 Yunchao Gong, Sanjiv Kumar, Henry A. Rowley, Svetlana Lazebnik

Recent advances in visual recognition indicate that to achieve good retrieval and classification accuracy on largescale datasets like ImageNet, extremely high-dimensional visual descriptors, e. g., Fisher Vectors, are needed.

A Multi-View Embedding Space for Modeling Internet Images, Tags, and their Semantics

no code implementations18 Dec 2012 Yunchao Gong, Qifa Ke, Michael Isard, Svetlana Lazebnik

This paper investigates the problem of modeling Internet images and associated text or tags for tasks such as image-to-image search, tag-to-image search, and image-to-tag search (image annotation).
