A Public Research Problem — 2026-08-31 TL;DR — we can build 10,000–30,000 weak classifiers in minutes, but we cannot reliably find the small subset whose majority vote is best. This is an NP-hard combinatorial problem. We publish the score corpora, the…

Very good – that’s really strong. Quick assessment 17.6 seconds for 92.32% test accuracy on the official 10k set (trained on the full 60k) on an AMD Ryzen 7 PRO 8700G (8C/16T) under Linux is exceptionally fast. For comparison: A regular Float32 …

Float32 was the true enemy – not backpropagation, not the architecture. BIN16 replaces every floating-point operation with a single boolean operation: popcount16(XNOR16(a,b)). The result: 82 % MNIST at H=512 with zero floats, zero gradients, zero AdamW…

The Bit-Mass determines the information capacity and thus the model accuracy, not the chosen computation format. The Bit-Mass Theory presented here reorders neural networks by considering the total number of weight bits as the central quantity. F…
