A$^{3}$lign-DFER: Pioneering Comprehensive Dynamic Affective Alignment for Dynamic Facial Expression Recognition with CLIP

no code implementations7 Mar 2024 Zeng Tao, Yan Wang, Junxiong Lin, Haoran Wang, Xinji Mai, Jiawen Yu, Xuan Tong, Ziheng Zhou, Shaoqi Yan, Qing Zhao, Liyuan Han, Wenqiang Zhang

Specifically, our A$^{3}$lign-DFER method is designed with multiple modules that work together to obtain the most suitable expanded-dimensional embeddings for classification and to achieve alignment in three key aspects: affective, dynamic, and bidirectional.

MDT-Net: Multi-domain Transfer by Perceptual Supervision for Unpaired Images in OCT Scan

no code implementations12 Mar 2022 Weinan Song, Gaurav Fotedar, Nima Tajbakhsh, Ziheng Zhou, Lei He, Xiaowei Ding

Furthermore, we take the transfer results as additional training data for fluid segmentation to prove the advantage of our model indirectly, i. e., in the task of data adaptation and augmentation.

C2P2: A Collective Cryptocurrency Up/Down Price Prediction Engine

no code implementations3 Jun 2019 Chongyang Bai, Tommy White, Linda Xiao, V. S. Subrahmanian, Ziheng Zhou

Moreover, we experimentally show that the use of similarity metrics within our C2P2 algorithm leads to a direct improvement for 20 out of 21 cryptocurrencies ranging from 0. 4% to 17. 8%.

Distributed Data Vending on Blockchain

no code implementations15 Mar 2018 Jiayu Zhou, Fengyi Tang, He Zhu, Ning Nan, Ziheng Zhou

However, one key challenge in distributed data vending is the trade-off dilemma between the effectiveness of data retrieval, and the leakage risk from indexing the data.
