Abstract

fetched live from OpenAlex

Based on the analysis of traditional wavelet speech denoise methods,a new wavelet denoie method is proposed,in which the ear masking property is used to design the shrink function.This method transforms the noisy speech into the wavelet spaces that reflect the ear hearing properties,then calculates the noise masking energies and adapts the factor in the shrink function,and then,the shrink function is used to process the noisy wavelet coefficients and,by inverse wavelet transforms,to gain the denoised speech.The experiments show that the better output NSR and PESQ of the enhanced speech could be gained by the proposed method.

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.
