Abstract
Presented are the investigations showing an impact of the length of data signals in hardware implemented Kohonen Self-Organizing Maps (SOM) on the quality of the learning process. The aim of this work was to determine the allowable reduction of the number of bits in particu- lar signals that does not deteriorate the network behavior. The eciency of the learning process has been quantied by using the quantization error. The results obtained for the SOM realized on Field Programmable Gate Array (FPGA), as well as by means of the software model of the SOM show that the smallest allowable resolution (expressed in bits) of the weight sig- nals equals seven, while the minimal bit length of the neighborhood signal ranges from 3 to 6 (depending on the map topology). For such values and properly selected values of other parameters the learning process remains undisturbed. Reducing the number of bits has an inuence on the number of neurons that can be synthesized on a single FPGA device.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
