White-Box Neural Network NanoEQL Decodes Nanocrystal Size Control
Researchers have introduced a novel interpretable neural network called the Nanocrystal Equation Learner (NanoEQL), aimed at elucidating the mechanisms behind size determination in nanocrystal synthesis. Unlike traditional deep learning models, which function as black boxes predicting size and shape based on precursors and reaction conditions, NanoEQL operates as a fully transparent white-box model utilizing the EQL architecture. It incorporates eight specialized operators in place of standard activation functions to align with the mathematical principles of nanocrystal synthesis, addressing gradient explosion issues with three smoothed operators. By employing a temperature-gated attention pooling strategy, the model effectively integrates concentration and reactivity-driven synthesis mechanisms. This research, detailed in arXiv under identifier 2608.14734, enhances understanding of the synthesis processes, marking progress toward transparent AI in materials science.
