To address this issue, this paper proposes an uncertainty-aware key-domain-preserving stacked auto-encoder (UADP-SAE) model developed to capture the spatiotemporal distribution characteristics of dynamic operational changes in industrial systems. Based on this, an uncertainty quantification framework is designed to guide feature learning of the model by using uncertainty estimates.

This enhances the learning effect and improves convergence speed. Experiments show a significant RMSE reduction from 18 μm to 0.83 μm (95.4 % improvement), and tracking errors are reduced by 51.1 % compared to PDILC under standard conditions and 48.9 % under additional load conditions.

This hybrid approach integrates the advantages of regression models in extracting precise and effective features with the superior performance of classification models in handling complex decision boundaries. Specifically, the regression network maps process variables to quality-related features, while the classification network then assigns these features to the corresponding product quality categories. Additionally, changes in the metabolic demands of microorganisms and the continuous consumption of substrates give rise to multi-stage dynamics, thereby further complicating the modeling process. To address this issue, a multi-stage segmentation approach is implemented within the classification network to more effectively capture the distinct phases of fermentation.
