A biologically inspired model of binocular control on a free head
Bibliographic record
Abstract
A single layer, symmetrical bilateral controller with dual modalities has been developed for a robotic head, based on symmetries in brainstem circuits for the oculomotor control system (OCS). This robotic head controller is unique in the biological approach during its development, and its structural elegance afforded by the single layer organization. Extensions to this controller are based on connections between brainstem and cerebellar structures, and the OCS circuit. To make the robotic head better reflect biology: 1. velocity feedback is added to account for floccular projections to the brainstem OCS, and 2. integral feedback is added to represent findings of vector averaging mechanisms in superior colliculus. The resulting OCS controller has a structure better matched with what has been reported in brainstem premotor-circuit topology. The new bilateral OCS not only retains the structural and analytical simplicity of its precursor, but it now has an improved bandwidth for its pursuit mode, and can track faster objects with smaller errors, while requiring fewer saccades.
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.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
