Evolving symbolic density functionals

1 code implementation3 Mar 2022 He Ma, Arunachalam Narayanaswamy, Patrick Riley, Li Li

Systematic development of accurate density functionals has been a decades-long challenge for scientists.

Kohn-Sham equations as regularizer: building prior knowledge into machine-learned physics

1 code implementation17 Sep 2020 Li Li, Stephan Hoyer, Ryan Pederson, Ruoxi Sun, Ekin D. Cubuk, Patrick Riley, Kieron Burke

Including prior knowledge is important for effective machine learning models in physics, and is usually achieved by explicitly adding loss terms or constraints on model architectures.

Scaling Symbolic Methods using Gradients for Neural Model Explanation

2 code implementations ICLR 2021 Subham Sekhar Sahoo, Subhashini Venugopalan, Li Li, Rishabh Singh, Patrick Riley

In this work, we propose a technique for combining gradient-based methods with symbolic techniques to scale such analyses and demonstrate its application for model explanation.

Decoding Molecular Graph Embeddings with Reinforcement Learning

no code implementations18 Apr 2019 Steven Kearnes, Li Li, Patrick Riley

We present RL-VAE, a graph-to-graph variational autoencoder that uses reinforcement learning to decode molecular graphs from latent embeddings.

Neural-Guided Symbolic Regression with Asymptotic Constraints

1 code implementation23 Jan 2019 Li Li, Minjie Fan, Rishabh Singh, Patrick Riley

The second part, which we call Neural-Guided Monte Carlo Tree Search, uses the network during a search to find an expression that conforms to a set of data points and desired leading powers.

Optimization of Molecules via Deep Reinforcement Learning

7 code implementations19 Oct 2018 Zhenpeng Zhou, Steven Kearnes, Li Li, Richard N. Zare, Patrick Riley

We present a framework, which we call Molecule Deep $Q$-Networks (MolDQN), for molecule optimization by combining domain knowledge of chemistry and state-of-the-art reinforcement learning techniques (double $Q$-learning and randomized value functions).

Tensor field networks: Rotation- and translation-equivariant neural networks for 3D point clouds

3 code implementations22 Feb 2018 Nathaniel Thomas, Tess Smidt, Steven Kearnes, Lusann Yang, Li Li, Kai Kohlhoff, Patrick Riley

We introduce tensor field neural networks, which are locally equivariant to 3D rotations, translations, and permutations of points at every layer.

Molecular Graph Convolutions: Moving Beyond Fingerprints

2 code implementations2 Mar 2016 Steven Kearnes, Kevin McCloskey, Marc Berndl, Vijay Pande, Patrick Riley

Molecular "fingerprints" encoding structural information are the workhorse of cheminformatics and machine learning in drug discovery applications.
