Neurosymbolic Router Hits 98.3% Reasoning Accuracy on a Raspberry Pi 4B

What the paper proposes

FAQ

What is a neurosymbolic router?

It is a component that classifies each incoming query and dispatches it to the cheapest correct solver: deterministic engines for structured tasks and a small language model for open-ended word problems.

How does it compare to Program-of-Thought?

On a Raspberry Pi 4B it reached 98.3% overall accuracy versus 72.0% for Program-of-Thought, while running 8.8x faster and 2.8x more energy-efficient in its 30-token configuration.

Should MENA teams adopt it now?

The paper reports research results on commodity edge hardware but does not ship a production-ready package; adoption requires reproducing the results and validating them on enterprise data first.
