Abstract

fetched live from OpenAlex

As the COVID-19 virus pandemic continues, we have seen a huge increase in concern for patient diagnosis and treatment or the human respiratory system. Combined with lack of effective treatment thus far, medical resources deem to be insufficient. Thus, an accurate and curated screening process to detect the early onset symptoms of this virus are greatly needed. In this paper, we propose the use of various machine learning techniques to showcase the efficacy of respiratory sound classification, ultimately attempting to improve upon the traditional physician diagnosis procedure. This proposed research work discovers unique classification methodology which offers a competitive alternative to a traditional hands-on approach, and aims to help develop novel data-driven models for identifying COVID-19 patient symptoms in their preliminary screenings during and after this pandemic.

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.
