Abstract

fetched live from OpenAlex

A new approach to interference reduction in digital subscriber line (DSL) networks is presented, which models the cross-coupling in DSL network as a multi-input, multi-output (MIMO) system. A constrained optimization technique is then used to improve the signal to noise ratio (SNR) of the lines by reducing the cross-coupling between the DSL lines. This is accomplished by assigning the lines to the customers in a way by which the interaction between the lines over the data frequency band is minimized. To achieve this, it is assumed that one may assign the DSL lines to the customers independently of their own phone lines.

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.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
