Abstract

fetched live from OpenAlex

The chip reported consists of an array of cells which functionally simulate the light-intensity-variation detecting neurons that exist in the retina of most highly developed animals. This chip performs motion detection using sub-nanoampere differentiation of the output currents of photodiodes arranged in a 2D array. As in most cases of image processing systems, the image projected onto the array must be time-invariant and spatially-variant. Experimental results show that fast moving images can be detected reliably by the array which dissipated a static power of less than 10 mu W. Images moving at a velocity lower than 1 mm/s can be detected if image contrast is high.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

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 distilled prediction

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.
