Abstract

fetched live from OpenAlex

Analyzing the sound resulting from a gunshot can help identify the type of gun used. This can help determine the appropriate public safety actions when a gunshot sound is detected in a public space. Furthermore, analyzing the sound can lead to a better understanding of the impact of this sound on hearing. For example, exposure to gunshot sounds can cause hearing impairments. Measuring these sounds from various locations and analyzing them can improve the design of hearing protectors and help enact regulations to minimize the impact of gunshot sounds on hearing impairments.

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.
