This invention discloses an online handwritten mathematical formula generation method based on a structure-aware latent space diffusion model. First, the input LaTeX expression is parsed to obtain symbol content, spatial topological relationships between symbols, and hierarchical depth information of the symbols, and a structured representation (RelAST) is constructed. Second, a generation framework based on a latent space conditional diffusion model is constructed, and a structure-aware sequence variational autoencoder is designed. By introducing symbol recognition constraints and structural relationship constraints, the latent representation simultaneously represents symbol semantics and spatial topological structure information. In the generation stage, using the structured representation (RelAST) as conditional input and combining prior information on the number of symbols, the target latent variable representation is generated in the latent space through the diffusion model. Finally, the decoder recovers the complete online handwritten trajectory sequence. This invention can effectively model the two-dimensional structural relationships of mathematical formulas, achieving unified generation of symbol content and spatial layout.
