CESPED: a new benchmark for supervised particle pose estimation in Cryo-EM

2 code implementations10 Nov 2023 Ruben Sanchez-Garcia, Michael Saur, Javier Vargas, Carl Poelking, Charlotte M Deane

Cryo-EM is a powerful tool for understanding macromolecular structures, yet current methods for structure reconstruction are slow and computationally demanding.

Pose Estimation

Embracing assay heterogeneity with neural processes for markedly improved bioactivity predictions

no code implementations17 Aug 2023 Lucian Chan, Marcel Verdonk, Carl Poelking

Predicting the bioactivity of a ligand is one of the hardest and most important challenges in computer-aided drug discovery.

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.

Contrastive Learning Drug Discovery

Meaningful machine learning models and machine-learned pharmacophores from fragment screening campaigns

no code implementations25 Mar 2022 Carl Poelking, Gianni Chessari, Christopher W. Murray, Richard J. Hall, Lucy Colwell, Marcel Verdonk

In this study we derive ML models from over 50 fragment-screening campaigns to introduce two important elements that we believe are absent in most -- if not all -- ML studies of this type reported to date: First, alongside the observed hits we use to train our models, we incorporate true misses and show that these experimentally validated negative data are of significant importance to the quality of the derived models.

BenchML: an extensible pipelining framework for benchmarking representations of materials and molecules at scale

2 code implementations4 Dec 2021 Carl Poelking, Felix A. Faber, Bingqing Cheng

We introduce a machine-learning (ML) framework for high-throughput benchmarking of diverse representations of chemical systems against datasets of materials and molecules.

Benchmarking Hyperparameter Optimization +1

Investigating 3D Atomic Environments for Enhanced QSAR

1 code implementation24 Oct 2020 William McCorkindale, Carl Poelking, Alpha A. Lee

Most approaches use molecular descriptors based on a 2D representation of molecules as a graph of atoms and bonds, abstracting away the molecular shape.

Noisy, sparse, nonlinear: Navigating the Bermuda Triangle of physical inference with deep filtering

no code implementations19 Nov 2019 Carl Poelking, Yehia Amar, Alexei Lapkin, Lucy Colwell

Capturing the microscopic interactions that determine molecular reactivity poses a challenge across the physical sciences.
