What is recorded here?
Selected attention layers using substitution-based importance, transferred compatible projections and expanded state capacity, then aligned hidden representations and adapted the full hybrid model with next-token training.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Per-input realization existence is not a common low-dimensional exact realization across all inputs; practical conversion is approximate and the selection score is a proxy. Although the abstract emphasizes layerwise alignment, method Section3.2.4 says end-to-end final-hidden-state MSE is the default after ablation. Reported savings exclude source pretraining; throughput uses8H200 GPUs, BF16 weights and FP32 recurrent state. The three-way SSM comparison is limited to the stated8B/50%-hybrid/Qwen setup.
