Abstract

fetched live from OpenAlex

An adaptive and computationally efficient filter is proposed for suppressing the unknown and non-stationary noise which exist in monochrome or colour images. This new methodology is based on estimating the unknown noise characteristics by using the generalized Gaussian probability density function (gGf). This function is used as a generic noise distribution model for various types of noise. Depending upon the shape parameter of the QGf, a specific model for the noise is assumed. It has been shown that the shape parameter, which characterizes the gGf, can be found easily by extracting the sample points from the corrupted image. Once the unknown noise distribution is modeled by the gGf, a suitable filter is utilized to smooth out the noise from the input image. Simulation results have shown that the proposed methodology is able to suppress effectively the unknown types of noise in the image.

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.

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.
