Teen dev builds integer-only neural net trainer in Rust, solves precision stall
A 10th-grade student created Green-AI, a neural network that uses only integer arithmetic to explore energy-efficient training. The standard approach stalled when weight updates rounded to zero, so he developed ABSL (Adaptive Bitshift Learning) to dynamically adjust precision. His fix reduced final weight error from 77 to near zero over 1000 runs.

The project is a clever hack, but scaling integer-only training to real-world models remains a huge challenge — this is a proof of concept, not a breakthrough.
