Abstract

fetched live from OpenAlex

In recent years, congruence transformation based model order reduction methods have proven to be an effective tool in dealing with increasing computational complexities which arise from the simulation of interconnect networks. However, most existing model order reduction methods are only efficient in coping with systems with small number of ports. Moreover, model order reduction methods based on Krylov subspace result in a macromodel which is not optimal. In this paper, a two-level reduction method is proposed to address the above two limitations. In the first level reduction, prior information about the types the loads that can be connected to the ports and their ranges of values is exploited to obtain a reduced macromodel whose size is not very sensitive to the number of ports. Since the first level reduction uses congruence transformation based on Krylov subspace techniques, which contain redundant information. This leads to a second level reduction using singular value decomposition. The proposed method is shown to produce a macromodel which is significantly smaller than standard methods.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
