Abstract

fetched live from OpenAlex

Optical coherence tomography (OCT) images suffer from speckle noise. The presence of noise may degrade the quality of the images which may further make diagnosis difficult. In this work, a wavelet transform based deep generative modeling based method has been proposed to extract multi-scale features to denoise OCT images. The OCT images contain edge information of different retinal layers, to avoid the over-smoothing effect and edge content loss, the Sobel edge detector based loss function has been designed to retain the edge information. The method is compared with other traditional and deep learning based methods in terms of commonly used image quality measures such as peak-signal-to-noise-ratio (PSNR), structural similarity (SSIM) and edge information with the variance of Laplacian.

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.
