TOD3Cap: Towards 3D Dense Captioning in Outdoor Scenes

1 code implementation28 Mar 2024 Bu Jin, Yupeng Zheng, Pengfei Li, Weize Li, Yuhang Zheng, Sujie Hu, Xinyu Liu, Jinwei Zhu, Zhijie Yan, Haiyang Sun, Kun Zhan, Peng Jia, Xiaoxiao Long, Yilun Chen, Hao Zhao

However, the exploration of 3D dense captioning in outdoor scenes is hindered by two major challenges: 1) the \textbf{domain gap} between indoor and outdoor scenes, such as dynamics and sparse visual inputs, makes it difficult to directly adapt existing indoor methods; 2) the \textbf{lack of data} with comprehensive box-caption pair annotations specifically tailored for outdoor scenes.

Entropy Neural Estimation for Graph Contrastive Learning

1 code implementation26 Jul 2023 Yixuan Ma, Xiaolin Zhang, Peng Zhang, Kun Zhan

In this paper, we theoretically illustrate that the entropy of a dataset can be approximated by maximizing the lower bound of the mutual information across different views of a graph, \ie, entropy is estimated by a neural network.

Generative approach to unsupervised deep local learning

1 code implementation19 Jun 2019 Changlu Chen, Chaoxi Niu, Xia Zhan, Kun Zhan

Based on the pretrained model and the constructed graph, we add a self-expressive layer to complete the generative model and then fine-tune it with a new loss function, including the reconstruction loss and a deliberately defined locality-preserving loss.
