Abstract

fetched live from OpenAlex

Recently, multiple-point simulation (MPS) was introduced to increase the accuracy of information extraction from remotely sensed imagery by incorporating structural information through a training image. An important procedure in the MPS-based information extraction method is the fusion of two probability fields from two different classifiers, extracting spectral and spatial structure information. In previous studies the fusion process was accomplished using the theory of evidence and the theory of consensus. It has been shown that these fusion methods each have their own capabilities and characteristics for different data under different circumstances. This paper investigates primarily the advantages and disadvantages of three different types of fusion methods: evidence-based, consensus-based, and probability-based, and then compares the fusion results through an accuracy assessment. For validation purposes, we selected two remotely sensed images taken in different areas and with distinct structural characteristics of roads. Both images, from Satellite Pour l'Observation de la Terre 5 (SPOT5) with spatial resolution of 10 m, were used to investigate the performance of the three fusion methods in extracting road information with distinct structural characteristics from the images. A comparison of the different fusion methods can assist users in selecting the appropriate fusion method for the given data characteristics. Based on the results of two experiments, the relationships between these fusion methods are further investigated.

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.
