This invention provides a parallel split learning method, apparatus, and system based on adaptive gradient correction, relating to the field of distributed machine learning computing technology. The invention receives intermediate layer gradients uploaded by each client, divides them into deep and shallow gradient components, calculates the consistency and comprehensive ranking score of each client's gradient, and generates an ordered gradient queue. Then, gradients are introduced one by one for weighted aggregation, directional stability judgment, and noise truncation to update the aggregation center. The comprehensive ranking score of high-confidence gradients is selected from the ordered gradient queue, and the global confidence score is calculated to dynamically adjust the global model parameters. A global reference direction is output and sent to each client, enabling each client to correct its gradients according to the global reference direction. The residual after gradient correction is used as a regularization constraint for the next round of local training optimization. This invention effectively suppresses gradient conflicts, improves model convergence speed and robustness, and reduces server computational overhead.
