Researchers have developed SCENT, a novel multi-modal contrastive learning framework designed to predict human olfactory perception directly from mass spectrometry data. This approach aligns electron ionization mass spectrometry (EI-MS) representations with chemical structure embeddings, eliminating the need for explicit molecular structure during inference. SCENT demonstrates strong performance in odor descriptor prediction, outperforming existing mass spectrometry-only methods and rivaling structure-based models, while also showing promise in approximating continuous human perceptual ratings and generalizing to real-world spectra.
