This repository provides a physically compressed and LoRA-healed checkpoint of google-bert/bert-base-uncased fine-tuned on GLUE SST-2, compressed using the subspace_projection (SubspaceProjectionCompressor) engine from the NeuralOps Library at Pareto-selected rank k=64 (3.11x compression ratio, -67.9% parameter reduction).

k=256, 128, 64, 32)Evaluated physically on NVIDIA GeForce RTX 3090 (24GB) on the GLUE SST-2 validation split (872 samples). Whenever zero-shot compression drops accuracy by > 2.0% alongside > 1.10x reduction, NeuralOps applies targeted r=8 LoRA healing (50 steps, lr=2e-4, 45s budget):
