Abstract Scope |
In this study, a model involving Gaussian Process Regression (GPR) is introduced to predict creep life based on chemical compositions of nickel-based superalloys, utilizing a large and heterogeneous dataset. The high variability in the data introduces significant challenges for model accuracy; thus, a clustering approach using K-means is used to split the entire dataset into more similar sets.
A separate GPR model is trained to capture the specific data patterns within each cluster. These individual kernels are then combined into a global kernel, representing the cumulative predictive power across clusters. This method enables a more adaptive modeling approach, improving predictive accuracy by leveraging the local similarities within each cluster. The proposed framework provides a robust tool for predicting creep life time in order to guide novel alloy design. |
