Abstract

fetched live from OpenAlex

In most areas of machine learning, it is assumed that data quality is fairly consistent between training and inference.Unfortunately, in real systems, data are plagued by noise, loss, and various other quality reducing factors.While a number of deep learning algorithms solve end-stage problems of prediction and classification, very few aim to solve the intermediate problems of data pre-processing, cleaning, and restoration.Long Short-Term Memory (LSTM) networks have previously been proposed as a solution for data restoration, but they suffer from a major bottleneck: a large number of sequential operations.We propose using attention mechanisms to entirely replace the recurrent components of these data-restoration networks.We demonstrate that such an approach leads to reduced model sizes by as many as 2 orders of magnitude, a 2-fold to 4-fold reduction in training times, and 95% accuracy for automotive data restoration.We also show in a case study that this approach improves the performance of downstream algorithms reliant on clean data.

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.
