OmniMotionGPT: Animal Motion Generation with Limited Data

no code implementations30 Nov 2023 Zhangsihao Yang, Mingyuan Zhou, Mengyi Shan, Bingbing Wen, Ziwei Xuan, Mitch Hill, Junjie Bai, Guo-Jun Qi, Yalin Wang

Our paper aims to generate diverse and realistic animal motion sequences from textual descriptions, without a large-scale animal text-motion dataset.

AdPE: Adversarial Positional Embeddings for Pretraining Vision Transformers via MAE+

1 code implementation14 Mar 2023 Xiao Wang, Ying Wang, Ziwei Xuan, Guo-Jun Qi

A criterion in unsupervised pretraining is the pretext task needs to be sufficiently hard to prevent the transformer encoder from learning trivial low-level features not generalizable well to downstream tasks.

Dual-Flattening Transformers through Decomposed Row and Column Queries for Semantic Segmentation

no code implementations22 Jan 2022 Ying Wang, Chiuman Ho, Wenju Xu, Ziwei Xuan, Xudong Liu, Guo-Jun Qi

We propose a Dual-Flattening Transformer (DFlatFormer) to enable high-resolution output by reducing complexity to $\mathcal{O}(hw(H+W))$ that is multiple orders of magnitude smaller than the naive dense transformer.
