Description

[0002] In recent years, artificial intelligence computing methods have made rapid progress in scientific computing, industrial forecasting and complex system modeling. With the widespread acquisition of multi-source data and the popularization of high-performance computing platforms, time series forecasting, graph neural networks and Transformer-type models based on deep learning have gradually become core tools for processing high-dimensional, unstructured and multimodal data.

[0003] However, existing technologies still have several limitations. First, traditional time series prediction methods rely heavily on one-way mapping of historical data, making it difficult to fully consider the coupling relationship between multiple sources of information, resulting in insufficient generalization ability in complex systems or unknown environments. Second, existing graph neural networks or Transformer models have high computational costs when processing high-dimensional continuous field data and lack explicit representation of hidden environmental variables, making it difficult to provide interpretability and long-term rolling stability. Third, existing fusion methods usually adopt simple weighting or end-to-end training strategies, lacking fine-tuning for spatial topological relationships and local neighborhood constraints, resulting in error accumulation in prediction results at local nodes or boundary regions.

The prediction results at each time point; The final prediction results are restored to spatial tensor form for subsequent visualization analysis.

7. The artificial intelligence calculation method as described in claim 6, characterized in that: The steps for constructing a joint loss function using node-level prediction results and training and updating the model parameters are as follows. Based on the deviation between the final prediction result and the actual result, a single-step prediction error term is constructed. Based on the multi-step recursive requirements in practical applications, a rolling stability term is defined. Introduce context-compact regularization and graph smoothing terms; The single-step prediction error term, rolling stability term, context compact regularization term, and graph smoothing term are jointly weighted to obtain the joint loss function, and the weighting weights are determined by cross-validation. The model is trained using real historical data as the training set, constrained by a joint loss function, optimized using the Adam optimizer with gradient descent, and its parameters are updated. The iteration stops and the model is output when the loss no longer decreases significantly during continuous iteration.

The temporal extrapolation module is used to perform low-rank embedding on the feature matrix of state nodes at each time point within the historical window, and to perform explicit temporal extrapolation on the embedding sequence based on the attention mechanism to generate basic prediction results that reflect the evolution trend of the system. The context extraction module is used to perform spatiotemporal pooling and concatenation on the feature sequences of state nodes and control nodes within the historical window, extract global context variables based on low-rank mapping, and broadcast the context variables to all spatial nodes to form a node-level context matrix. The spatial correction module is used to splice the joint input matrix, extract axial features along each spatial axis and calculate the axial relationship kernel matrix, construct the implicit correction kernel matrix by combining the spatial adjacency matrix, and perform spatial correction on the joint input matrix to generate spatial correction increments. The prediction output module is used to generate a gating coefficient matrix based on the joint input. Based on the gating coefficient matrix, the basic prediction results and the spatial correction increment are weighted and fused element by element to obtain the final prediction node matrix.
