Abstract

fetched live from OpenAlex

We present a new algorithm for the adaptive estimation of the tap weights of an unknown linear transversal filter. This algorithm takes advantage of the fast convergence properties of some recently developed interior-point optimization techniques. In particular, we use ideas from interior-point column generation methods, whose iterative nature lends itself well to applications that require adaptive solutions. Numerical simulations demonstrate that the new algorithm compares well against RLS, in terms of convergence speed, especially when conditions are adverse (i.e., SNR is low, input signal is correlated, systems are time-varying).

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
