Abstract

fetched live from OpenAlex

Pattern recognition techniques currently used in remote sensing analysis are supervised and unsupervised classification methods. However, remotely sensed imagery can be distorted by many factors, for instance the surface slope, illumination and atmospheric effects, which will cause the classification errors. In order to improve classification accuracy, other types of information are needed such as the interrelationships between pixels or regions, previous classification results or existing map data, photometric or geometric properties on the area. This paper introduces an approach in which spatial information commonly stored in geographic information systems (GIS) is incorporated to assist the remote sensing image classification. The experimental results show that it is advantageous to use the spatial information in remote sensing analysis.

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.
