AI model learns chemical properties from molecular data, controlling for sequence shortcuts

Researchers have developed a new method to evaluate molecular generative models, specifically Transformer-VAEs trained on SELFIES. Their approach addresses the issue where apparent property predictability might stem from sequence shortcuts rather than true chemical organization. By introducing a confound-aware evaluation, they can more accurately assess the chemical meaningfulness of latent spaces and demonstrate robust steering for several chemical properties. AI
