New transformer-based model for identifying alloy properties
In this study, we introduce AlloyBERT, a transformer encoder model tuned to predict properties such as elastic modulus and yield strength of alloys based on text input. Credit: https://github.com/cakshat/AlloyBERT?tab=readme-ov-file Determining alloy properties can be expensive and time consuming. Experiments with alloys are often resource intensive. Alloy calculations can also be very complex, with a seemingly infinite number of configurations of…
