Éric Martin, Xiang‐Wei Zhu · ChemRxiv · 2020
Article describing collaborative modeling between competitor companies by sharing single-task models and incorporating them into stacked multi-task Profile-QSAR models, without sharing chemical structures, activity data or biological targets. Data are ~20 million pIC50s from ~12,000 Novartis internal dose-response assays tested on a total of ~1.9 million compounds. They were divided into pseudo-companies based on the several companies that historically merged to form Novartis.
