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).

Graph Convolution: A High-Order and Adaptive Approach

no code implementations29 Jun 2017 Zhenpeng Zhou, Xiaocheng Li

In this paper, we presented a novel convolutional neural network framework for graph modeling, with the introduction of two new modules specially designed for graph-structured data: the $k$-th order convolution operator and the adaptive filtering module.
