The invention belongs to the field of
bioinformatics, and relates to a
molecular property prediction method based on multi-
modal gating and comparative learning, which comprises the technologies of comparative learning, graph neural network, cross-
modal alignment, gating attention and the like. Firstly, data
standardization and graph construction are carried out, and
molecular fingerprint embedding is extracted; secondly, a heterogeneous dual-channel graph coding architecture is adopted, one path captures atom short-range interaction through an attention mechanism, the other path integrates a molecular
global structure and long-range dependence, and complementary molecular representation is generated; then, a cross-
modal attention mechanism is introduced, bidirectional association of graph and
fingerprint features is achieved, and modal weights are adaptively and dynamically distributed through a gating fusion module; and finally, a comparison pre-training strategy is adopted, a
molecular graph and fingerprints are utilized to construct a sample pair, and discriminative molecular representation is learned on unlabeled data. According to the method, the accuracy of
molecular property prediction is remarkably improved, and an efficient and reliable calculation tool is provided for virtual
drug screening and
lead compound optimization.
