Abstract
This paper presents an efficient architecture of a fixed-point Fast Independent Component analysis (FastICA) in field programmable gate array (FPGA). The algorithm separates up to four signals using four sensors. A prestage QR decomposition is used to improve the speed of eigenvalues and eigenvectors evaluation of the covariance matrix. Moreover, a symmetric orthogonalization of the unit estimation algorithm is implemented using an iterative technique to speed up the search algorithm for higher order data input. The algorithm is implemented using Xilinx Virtex5-XC5VLX50t FPGA. The proposed architecture can process 128 samples for the four sensors in less than 2.5 ms when the design is simulated using 100 MHz clock.

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
