Abstract: For viability determination with self-attention for process optimization, various process and state information in the manufacture (e.g., forming, assembling, and/or handling) of a part are embedded. A machine-learned model generates the embedding, which is used with self-attention similarity to identify similar cases based on the embedding. The model was trained using both regression for continuous information (e.g., variable names) in the embedding and classification for non-continuous information (e.g., value of a variable) in the embedding. By including both regression and classification, the same machine-learned model may be used for reliable and nuanced viability determination.
