Abstract Scope |
Optimizing dental material properties have shown to be a challenging task to overcome due to the high dimensionality of the formulation space. This complexity is further enhanced due to the competing objectives of dental materials, such compressive strength and shrinkage stress. Here we investigate an innovative approach to optimizing dental composite formulations using Gaussian Process Latent Variable Models (GPLVM) and Active Learning. By leveraging GPLVM, we reduce the complexity of high-dimensional formulation space, by capturing essential relationships in a lower-dimensional latent space. This enables efficient optimization of key objectives, such as maximizing compressive strength and minimizing shrinkage stress. Our method integrates a robust active learning framework, iteratively refining the model with new experimental data to enhance predictive accuracy. |
