There is a lack of scalable quantitative measures of reactivity that cover the full range of functional groups in organic chemistry, ranging from highly unreactive C-C bonds to highly reactive naked ions. Measuring reactivity experimentally is costly...

Neural Network Potentials: A Concise Overview of Methods.

Annual review of physical chemistry
In the past two decades, machine learning potentials (MLPs) have reached a level of maturity that now enables applications to large-scale atomistic simulations of a wide range of systems in chemistry, physics, and materials science. Different machine...

Synergy and Complementarity between Focused Machine Learning and Physics-Based Simulation in Affinity Prediction.

Journal of chemical information and modeling
We present results on the extent to which physics-based simulation (exemplified by FEP) and focused machine learning (exemplified by QuanSA) are complementary for ligand affinity prediction. For both methods, predictions of activity for LFA-1 inhibit...

The LHC Olympics 2020 a community challenge for anomaly detection in high energy physics.

Reports on progress in physics. Physical Society (Great Britain)
A new paradigm for data-driven, model-agnostic new physics searches at colliders is emerging, and aims to leverage recent breakthroughs in anomaly detection and machine learning. In order to develop and benchmark new anomaly detection methods within ...

Deep neural network enabled corrective source term approach to hybrid analysis and modeling.

Neural networks : the official journal of the International Neural Network Society
In this work, we introduce, justify and demonstrate the Corrective Source Term Approach (CoSTA)-a novel approach to Hybrid Analysis and Modeling (HAM). The objective of HAM is to combine physics-based modeling (PBM) and data-driven modeling (DDM) to ...
