Automated 3D Pre-Training for Molecular Property Prediction

1 code implementation13 Jun 2023 Xu Wang, Huan Zhao, WeiWei Tu, Quanming Yao

Next, to automatically fuse these three generative tasks, we design a surrogate metric using the \textit{total energy} to search for weight distribution of the three pretext task since total energy corresponding to the quality of 3D conformer. Extensive experiments on 2D molecular graphs are conducted to demonstrate the accuracy, efficiency and generalization ability of the proposed 3D PGT compared to various pre-training baselines.

Differential Private Stack Generalization with an Application to Diabetes Prediction

no code implementations23 Nov 2018 Quanming Yao, Xiawei Guo, James T. Kwok, WeiWei Tu, Yuqiang Chen, Wenyuan Dai, Qiang Yang

To meet the standard of differential privacy, noise is usually added into the original data, which inevitably deteriorates the predicting performance of subsequent learning algorithms.
