Abstract

fetched live from OpenAlex

Abstract Stochastic computing (SC) is an approximate computing paradigm using probabilities and aims at realizing circuits with low hardware cost. Basic operations (such as addition) have been comprehensively studied, whereas there are few studies on nonlinear operations (such as division and square root) in SC. In this paper, a stochastic division circuit is proposed by using maximally correlated input bitstreams to eliminate the necessity for distinguishing the divisor and dividend. Additionally, four stochastic square root circuits are designed with improved accuracy by decreasing the correlation between intermediate bitstreams via inserting delay elements. Experimental results show that both the proposed division and square root circuits achieve lower mean squared errors (MSEs) while requiring nearly the same hardware resources, compared with the state‐of‐the‐art designs. This result shows the potential in exploiting signal correlation in SC circuit design for high accuracy.

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.
