The Reaction Model Followed the Electrons
MAELLE represents chemical reactions as discrete flow through electron-occupation space instead of direct molecular graph edits.
Summary
MAELLE represents chemical reactions as discrete flow through electron-occupation space instead of direct molecular graph edits.
The method uses a continuous-time Markov chain and optimal-transport paths to produce interpretable electron rearrangements without elementary-step annotations. Its authors report competitive USPTO-480K accuracy, stronger robustness on two out-of-distribution settings and the ability to recover plausible mechanisms and side products; those benchmark results are not laboratory validation of a proposed reaction.
Why it matters
