Researchers have developed a multimodal deep learning approach to improve the identification of small-molecule structures using spectroscopic data. By incorporating domain knowledge from chemistry and spectroscopy into a mixed-condition training strategy, the model enhances robustness against missing, degraded, or mismatched spectral inputs. This method, utilizing a mixture-of-experts (MoE) fusion, significantly improved performance metrics such as mean reciprocal rank (MRR) and recall at rank 1, particularly for individual spectroscopic modalities.
