Abstract

fetched live from OpenAlex

Stochastic computing (SC) utilizes a random binary bit stream to encode a number by counting the frequency of 1's in the stream (or sequence). Typically, a small circuit is used to perform a bit-wise logic operation on the stochastic sequences, which leads to significant hardware and power savings. Energy efficiency, however, is a challenge for SC due to the long sequences required for accurately encoding numbers. To overcome this challenge, we consider to use a stochastic sequence to encode a continuously variable signal instead of a number to achieve higher accuracy, higher energy efficiency and greater flexibility. Specifically, one single bit is used to encode a sample from a signal for efficient processing. This type of sequences encodes constantly variable values, so it is referred to as dynamic stochastic sequences (DSS's). The DSS enables the use of SC circuits to efficiently perform tasks such as frequency mixing and function estimation. It is shown that such a dynamic SC (DSC) system achieves savings up to 98.4% in energy and up to 96.8% in time with a slightly higher accuracy compared to conventional SC. It also achieves energy and time savings of up to 60% compared to a fixed-width binary implementation.

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.
