Abstract

fetched live from OpenAlex

Abstract Retrieval processes provide ways of using memory. This chapter describes three important ways of using memory, with a focus on using memory to make decisions about visual objects. Discrimination is deciding if an object is distinct from another object experienced at the same time or moments ago, recognition is deciding if an object is the same as an object experienced some time in the past, and classification is deciding what kind of object something is. All three require comparing the representation of a currently perceived object with representations retrieved from memory to drive a decision process. The chapter discusses the component mechanisms for discrimination, recognition, and classification as formally instantiated in computational models and also discusses relationships between model mechanisms and brain mechanisms as revealed by neuropsychology and brain imaging.

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.
