Deep learning for molecular design—a review of the state of the art
TLDR
Several important high level themes emerge, including the shift away from the SMILES string representation of molecules towards more sophisticated representations such as graph grammars and 3D representations, the importance of reward function design, the need for better standards for benchmarking and testing, and the benefits of adversarial training and reinforcement learning over maximum likelihood based training.
Deep learning for molecular generation and optimization - a review of the state of the art
TLDR
A recent groundswell of work which uses deep learning techniques to generate and optimize molecules and how these techniques improve the quality of existing molecules is reviewed.

Applying machine learning techniques to predict the properties of energetic materials
TLDR
This work presents a comprehensive comparison of machine learning models and several molecular featurization methods - sum over bonds, custom descriptors, Coulomb matrices, Bag of Bonds, and fingerprints - and concludes that the best featurizing was sum over bond counting, and the best model was kernel ridge regression.

A New Riemannian Averaged Fixed-Point Algorithm for MGGD Parameter Estimation
TLDR
This work proposes a new FP algorithm, Riemannian averaged FP (RA-FP), which can effectively estimate the scatter matrix for any value of the shape parameter and provides significantly improved performance over existing FP and method-of-moments algorithms for the estimation of the scattering matrix.

Independent Vector Analysis for Molecular Data Fusion: Application to Property Prediction and Knowledge Discovery of Energetic Materials
TLDR
This work proposes a data fusion framework that uses Independent Vector Analysis to uncover underlying complementary information contained in different molecular featurization methods and generates a low dimensional set of features—molecular signatures—that can be used for the prediction of molecular properties and for knowledge discovery.
