3D pride without 2D prejudice: Bias-controlled multi-level generative models for structure-based ligand design

no code implementations22 Apr 2022 Lucian Chan, Rajendra Kumar, Marcel Verdonk, Carl Poelking

Generative models for structure-based molecular design hold significant promise for drug discovery, with the potential to speed up the hit-to-lead development cycle, while improving the quality of drug candidates and reducing costs.

Hyperparameter Learning via Distributional Transfer

1 code implementation NeurIPS 2019 Ho Chung Leon Law, Peilin Zhao, Lucian Chan, Junzhou Huang, Dino Sejdinovic

Bayesian optimisation is a popular technique for hyperparameter learning but typically requires initial exploration even in cases where similar prior tasks have been solved.
