Abstract

fetched live from OpenAlex

Most biologically-inspired models of object recognition rely on a feed-forward architecture in which abstract representations are gradually built from simple representations, but recognition performance in such systems drops when multiple objects are present in the input. This chapter puts forward the proposal that by using multiple passes of the visual processing hierarchy, both bottom-up and top-down, it is possible to address the limitations of feed-forward architectures and explain the different recognition behaviors that primate vision exhibits. The model relies on the reentrant connections that are ubiquitous in the primate brain to recover spatial information, and thus allow for the selective processing of stimuli. The chapter ends with a discussion of the implications of this work, its explanatory power, and a number of predictions for future experimental work.

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.
