Abstract

fetched live from OpenAlex

In hyperspectral remote sensing, the conventional endmember extraction and unmixing procedures are often complex and associated with uncertainties. In this work, we have designed an algorithm that uses Crude Low Pass Filter (CLoPF) and Pearson's Correlation Coefficient (PCC) to identify the endmember spectra from spectral library. Subsequently, a Non-Negativity Fully Constrained Least Square (NNFCLS) optimization approach was used to determine the fractional abundances of identified end-members. The efficacy of adopted procedure was estimated by Normalized Root Mean Squared Deviation (NRMSD), Spectral Angular Mapper (SAM), computation timing and appropriateness of identified candidates. It is observed that this procedure can be effectively used to resolve the mix-pixel spectra into library constituents and its fractional abundances.

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.
