Entity Set Search of Scientific Literature: An Unsupervised Ranking Approach

1 code implementation29 Apr 2018 Jiaming Shen, Jinfeng Xiao, Xinwei He, Jingbo Shang, Saurabh Sinha, Jiawei Han

Different from Web or general domain search, a large portion of queries in scientific literature search are entity-set queries, that is, multiple entities of possibly different types.

Triplet-Center Loss for Multi-View 3D Object Retrieval

1 code implementation CVPR 2018 Xinwei He, Yang Zhou, Zhichao Zhou, Song Bai, Xiang Bai

Most existing 3D object recognition algorithms focus on leveraging the strong discriminative power of deep learning models with softmax loss for the classification of 3D data, while learning discriminative features with deep metric learning for 3D object retrieval is more or less neglected.
