SOON: Scenario Oriented Object Navigation with Graph-based Exploration.
TL;DR: In this article, a novel graph-based exploration (GBE) method is proposed to solve the scenario-oriented object navigation (SOON) task, where an agent is required to navigate from an arbitrary position in a 3D embodied environment to localize a target following a scene description.

Multiview Latent Structure Learning: Local structure-guided cross-view discriminant analysis
TL;DR: In this paper , a multiview Latent Structure Learning (MvLSLSTL) model is proposed to take more consideration of the relationship between any two classes and incorporate the weighted harmonic mean of pairwise between-class scatter and pairwise withinclass scatter.

Memory transformation networks for weakly supervised visual classification
TL;DR: A Memory Transformation Network (MTN) is proposed to convert external knowledge, by involving embedded and concentrated memories, so as to leverage it feasibly for video classification with weak supervision, and outperforms the state-of-the-arts on visual classification with limited labeled exemplars.
