Autoregressive fragment-based diffusion for pocket-aware ligand design

no code implementations15 Dec 2023 Mahdi Ghorbani, Leo Gendelev, Paul Beroza, Michael J. Keiser

In this work, we introduce AutoFragDiff, a fragment-based autoregressive diffusion model for generating 3D molecular structures conditioned on target protein structures.

Robust Semantic Interpretability: Revisiting Concept Activation Vectors

1 code implementation6 Apr 2021 Jacob Pfau, Albert T. Young, Jerome Wei, Maria L. Wei, Michael J. Keiser

Our proposed Robust Concept Activation Vectors (RCAV) quantifies the effects of semantic concepts on individual model predictions and on model behavior as a whole.

Attention-Based Learning on Molecular Ensembles

no code implementations25 Nov 2020 Kangway V. Chuang, Michael J. Keiser

The three-dimensional shape and conformation of small-molecule ligands are critical for biomolecular recognition, yet encoding 3D geometry has not improved ligand-based virtual screening approaches.

Global Saliency: Aggregating Saliency Maps to Assess Dataset Artefact Bias

no code implementations16 Oct 2019 Jacob Pfau, Albert T. Young, Maria L. Wei, Michael J. Keiser

In high-stakes applications of machine learning models, interpretability methods provide guarantees that models are right for the right reasons.
