A high-performance, memory-aware Bayesian inference core designed for large-scale parameter efficiency on consumer hardware.
The Neuro-Symbolic Engine (v1.0) is a C++/CUDA implementation of a memory-efficient Bayesian neural architecture. It utilizes 8-bit Probabilistic Superposition and Gated Recurrent Units (GRU) to enable high-parameter modeling within a strictly controlled memory footprint (~14GB VRAM for 7B scale).

The engine replaces floating-point weight tensors with an 8-bit Probabilistic Superposition. This allows for a categorical reduction in training RAM, enabling 7B parameter models to stay within the 14-16GB VRAM limit of prosumer GPUs.
By implementing High-Contrast Initialization for the Feedback Matrix (WB), the engine maintains a superior signal-to-noise ratio for DFA error signals. This prevents gradient vanishing in deep neuro-symbolic chains.
The probabilistic update kernels are synchronized with forward matmul tiling, ensuring absolute mathematical integrity during weight updates. This is verified by the consistent convergence observed in 1024-unit core tests.
