Group SELFIES: A Robust Fragment-Based Molecular String Representation

1 code implementation23 Nov 2022 Austin Cheng, Andy Cai, Santiago Miret, Gustavo Malkomes, Mariano Phielipp, Alán Aspuru-Guzik

We introduce Group SELFIES, a molecular string representation that leverages group tokens to represent functional groups or entire substructures while maintaining chemical robustness guarantees.

Accelerating Psychometric Screening Tests With Bayesian Active Differential Selection

no code implementations4 Feb 2020 Trevor J. Larsen, Gustavo Malkomes, Dennis L. Barbour

Classical methods for psychometric function estimation either require excessive measurements or produce only a low-resolution approximation of the target psychometric function.

Efficient nonmyopic batch active search

no code implementations NeurIPS 2018 Shali Jiang, Gustavo Malkomes, Matthew Abbott, Benjamin Moseley, Roman Garnett

A critical target scenario is high-throughput screening for scientific discovery, such as drug or materials discovery.

Drug Discovery

Efficient nonmyopic active search with applications in drug and materials discovery

no code implementations21 Nov 2018 Shali Jiang, Gustavo Malkomes, Benjamin Moseley, Roman Garnett

We also study the batch setting for the first time, where a batch of $b>1$ points can be queried at each iteration.

Efficient Nonmyopic Active Search

no code implementations ICML 2017 Shali Jiang, Gustavo Malkomes, Geoff Converse, Alyssa Shofner, Benjamin Moseley, Roman Garnett

Active search is an active learning setting with the goal of identifying as many members of a given class as possible under a labeling budget.

Bayesian optimization for automated model selection

no code implementations NeurIPS 2016 Gustavo Malkomes, Charles Schaff, Roman Garnett

Despite the success of kernel-based nonparametric methods, kernel selection still requires considerable expertise, and is often described as a “black art.” We present a sophisticated method for automatically searching for an appropriate kernel from an infinite space of potential choices.

Bayesian Active Model Selection with an Application to Automated Audiometry

no code implementations NeurIPS 2015 Jacob Gardner, Gustavo Malkomes, Roman Garnett, Kilian Q. Weinberger, Dennis Barbour, John P. Cunningham

Using this and a previously published model for healthy responses, the proposed method is shown to be capable of diagnosing the presence or absence of NIHL with drastically fewer samples than existing approaches.
