Abstract

fetched live from OpenAlex

Orientation is concerned with “sidedness”, a concept that is intuitively obvious but surprisingly difficult to formulate in a mathematically rigorous fashion. This chapter makes a few observations based on concrete examples, and then presents a preliminary definition of orientation for Rm. These ideas are developed into a computational framework for arbitrary vector spaces using the recently acquired knowledge of multicovectors. The chapter presents an equivalent approach to orientation using multicovectors. It also generalizes the well-known vector product in R3 to an arbitrary scalar product space. The vector product has a number of interesting algebraic properties, several of which, not surprisingly, are expressed in terms of determinants and wedge products. The chapter further defines a map that assigns to a given multicovector another multicovector that “complements” the first. The methods that result add to the growing armamentarium of techniques for computing with multicovectors.

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.
