Abstract

fetched live from OpenAlex

The objective of this research is to examine whether or not the same dataset, geocoded using different methods, produces significantly different results when applying various methods used to examine both first and second order effects of a point pattern dataset. Observations from Sydney, Nova Scotia, Canada, and vicinity were geocoded in two ways: using a civic address point file derived from 20cm resolution orthophotos; and postal code geocoding using two different products. The resulting three point patterns were analysed using a bivariate K‐function, a ratio of kernel estimates and Kuldorff's spatial scan statistic. Analysis indicates that conclusions can vary depending on geocoding, while of the methods tested the bivariate K‐function produces results that are least affected by the type of geocoding employed.

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.
