Optical Wavelength Guided Self-Supervised Feature Learning For Galaxy Cluster Richness Estimate

no code implementations4 Dec 2020 Gongbo Liang, Yuanyuan Su, Sheng-Chieh Lin, Yu Zhang, Yuanyuan Zhang, Nathan Jacobs

We believe the proposed method will benefit astronomy and cosmology, where a large number of unlabeled multi-band images are available, but acquiring image labels is costly.


Deep Fusion: An Attention Guided Factorized Bilinear Pooling for Audio-video Emotion Recognition

no code implementations15 Jan 2019 Yuanyuan Zhang, Zi-Rui Wang, Jun Du

Although there is no consensus on a definition, human emotional states usually can be apperceived by auditory and visual systems.

Generating survival times using Cox proportional hazards models with cyclic time-varying covariates, with application to a multiple-dose monoclonal antibody clinical trial

1 code implementation25 Jan 2018 Yunda Huang, Yuanyuan Zhang, Zong Zhang, Peter B. Gilbert

In two harmonized efficacy studies to prevent HIV infection through multiple infusions of the monoclonal antibody VRC01, a key objective is to evaluate whether the serum concentration of VRC01, which changes cyclically over time along with the infusion schedule, is associated with the rate of HIV infection.
