Abstract

fetched live from OpenAlex

A novel ordinary differential equation (ODE) solver is proposed by using a stochastic integrator to implement the accumulative function of the Euler method. We show that a stochastic integrator is an unbiased estimator for a Euler numerical solution. Unlike in conventional stochastic circuits, in which long stochastic bit streams are required to produce a result with a high accuracy, the proposed stochastic ODE solver provides an estimate of the solution for every bit in the stochastic bit stream, thus significantly reducing the latency and energy consumption of the circuit. Complex ODE solvers are constructed for solving nonhomogeneous ODEs, systems of ODEs and higher-order ODEs. Experimental results show that the stochastic ODE solvers provide very accurate solutions compared to their binary counterparts, with on average an energy saving of 46% (up to 74%), 8x throughput per area (up to nearly 12x) and a runtime reduction of 72% (up to 82%).

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
