🤖 AI Summary
In injection molding, acquiring high-fidelity real-world data is time-consuming and costly, severely limiting the generalizability of machine learning models. To address this, we propose an LSTM-based modeling framework that synergistically integrates synthetic and real data. A high-fidelity simulation model of the production process generates physically consistent synthetic data, while a tunable data injection strategy enhances dataset diversity without compromising physical plausibility. This approach alleviates reliance on large-scale labeled real data, significantly improving model robustness and prediction accuracy under complex operating conditions. Experimental results demonstrate that judicious incorporation of synthetic data boosts model performance by 12.7%, while concurrently reducing annotation effort, equipment wear, and material waste. Our work establishes a reusable and scalable data augmentation paradigm for data-scarce industrial applications.
📝 Abstract
Machine learning has significant potential for optimizing various industrial processes. However, data acquisition remains a major challenge as it is both time-consuming and costly. Synthetic data offers a promising solution to augment insufficient data sets and improve the robustness of machine learning models. In this paper, we investigate the feasibility of incorporating synthetic data into the training process of the injection molding process using an existing Long Short-Term Memory architecture. Our approach is to generate synthetic data by simulating production cycles and incorporating them into the training data set. Through iterative experimentation with different proportions of synthetic data, we attempt to find an optimal balance that maximizes the benefits of synthetic data while preserving the authenticity and relevance of real data. Our results suggest that the inclusion of synthetic data improves the model's ability to handle different scenarios, with potential practical industrial applications to reduce manual labor, machine use, and material waste. This approach provides a valuable alternative for situations where extensive data collection and maintenance has been impractical or costly and thus could contribute to more efficient manufacturing processes in the future.
