Abstract

fetched live from OpenAlex

It has been widely recognized that the dynamic range information of an application can be exploited to reduce the datapath bitwidth of either processors or ASICs, and therefore the overall circuit area, delay, and power consumption. Recent advances in analytical dynamic range estimation methods indicate that by systematically decomposing the system inputs into orthonormal random variables using a mathematical procedure called polynomial chaos expansion (PCE), output statistics of interest can be obtained for both linear and nonlinear systems. Despite its power for capturing both spatial and temporal correlation, the application of this method has been limited only to near-Gaussian inputs. In this paper, we propose the first algorithm with the capacity of handling both near-Gaussian and non-Gaussian input signals. Our method is based on the use of independent component analysis (ICA). Our experiments show that the new algorithm can reduce the original relative errors of 2nd order moments from 25%-65% to 1%-2%.

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.
