The invention discloses a spatial multi-
omics data integration method based on graph attention and a multivariate
loss function. Comprising the following steps that spatial multi-
omics data and spatial position coordinates corresponding to the spatial multi-
omics data are obtained, a preset spatial multi-
omics data model is input, and the model comprises a graph attention
encoder and a decoder; the spatial multi-
omics data model constructs a graph structure according to spatial multi-
omics data and spatial position coordinates, a graph attention
encoder performs
cell spatial multi-omics data fusion based on the constructed graph structure, and a decoder performs
data reconstruction based on fused data to complete
cell spatial multi-omics
data integration; and constructing a multivariate
loss function to carry out iterative optimization on the
cell space multi-omics
data integration process of the space multi-omics
data model, and outputting an optimal
cell space multi-omics data integration result. According to the method, the batch effect is solved, the smoothness of a final result in space and the accuracy of
spatial analysis are improved, and the integration of multi-omics data of the
cell space is realized.
