TAMM: TriAdapter Multi-Modal Learning for 3D Shape Understanding

no code implementations28 Feb 2024 Zhihao Zhang, Shengcao Cao, Yu-Xiong Wang

The limited scale of current 3D shape datasets hinders the advancements in 3D shape understanding, and motivates multi-modal learning approaches which transfer learned knowledge from data-abundant 2D image and language modalities to 3D shapes.

Aligning Large Multimodal Models with Factually Augmented RLHF

no code implementations25 Sep 2023 Zhiqing Sun, Sheng Shen, Shengcao Cao, Haotian Liu, Chunyuan Li, Yikang Shen, Chuang Gan, Liang-Yan Gui, Yu-Xiong Wang, Yiming Yang, Kurt Keutzer, Trevor Darrell

Large Multimodal Models (LMM) are built across modalities and the misalignment between two modalities can result in "hallucination", generating textual outputs that are not grounded by the multimodal information in context.

Learning Lightweight Object Detectors via Multi-Teacher Progressive Distillation

no code implementations17 Aug 2023 Shengcao Cao, Mengtian Li, James Hays, Deva Ramanan, Yi-Xiong Wang, Liang-Yan Gui

To distill knowledge from a highly accurate but complex teacher model, we construct a sequence of teachers to help the student gradually adapt.

Contrastive Mean Teacher for Domain Adaptive Object Detectors

1 code implementation CVPR 2023 Shengcao Cao, Dhiraj Joshi, Liang-Yan Gui, Yu-Xiong Wang

Object detectors often suffer from the domain gap between training (source domain) and real-world applications (target domain).

Rethinking Transformer-based Set Prediction for Object Detection

1 code implementation ICCV 2021 Zhiqing Sun, Shengcao Cao, Yiming Yang, Kris Kitani

DETR is a recently proposed Transformer-based method which views object detection as a set prediction problem and achieves state-of-the-art performance but demands extra-long training time to converge.

Learnable Embedding Space for Efficient Neural Architecture Compression

2 code implementations ICLR 2019 Shengcao Cao, Xiaofang Wang, Kris M. Kitani

We also demonstrate that the learned embedding space can be transferred to new settings for architecture search, such as a larger teacher network or a teacher network in a different architecture family, without any training.
