A Deep and Autoregressive Approach for Topic Modeling of Multimodal Data
Yin Zheng, Yu-Jin Zhang, Hugo Larochelle
Topic modeling based on latent Dirichlet allocation (LDA) has been a framework of choice to deal with multimodal data, such as in image annotation tasks. Another popular approach t…
Image Tag Completion by Low-rank Factorization with Dual Reconstruction Structure Preserved
Xue Li, Yu-Jin Zhang, Bin Shen +1
A novel tag completion algorithm is proposed in this paper, which is designed with the following features: 1) Low-rank and error s-parsity: the incomplete initial tagging matrix D…
Image retrieval with hierarchical matching pursuit
Shasha Bu, Yu-Jin Zhang
A novel representation of images for image retrieval is introduced in this paper, by using a new type of feature with remarkable discriminative power. Despite the multi-scale natur…
A Supervised Neural Autoregressive Topic Model for Simultaneous Image Classification and Annotation
Yin Zheng, Yu-Jin Zhang, Hugo Larochelle
Topic modeling based on latent Dirichlet allocation (LDA) has been a framework of choice to perform scene recognition and annotation. Recently, a new type of topic model called the…
A Gradient Descent Algorithm on the Grassman Manifold for Matrix Completion
Raghunandan H. Keshavan, Sewoong Oh
We consider the problem of reconstructing a low-rank matrix from a small subset of its entries. In this paper, we describe the implementation of an efficient algorithm called OptSp…
