1. Interpretable Safety Alignment via SAE-Constructed Low-Rank Subspace Adaptation (2026)
   LoRA-based safety tuning usually falls short of full fine-tuning and RL-based alignment, even though earlier work suggests that LLM safety behavior lives in low-rank structures.
2. SCVQ: Sparse-Compensated Vector Quantization for Large Language Models (2026)
   Vector quantization (VQ) compresses LLM weights well at very low bit-widths, but it is slow in practice. Large codebooks and frequent table lookups consume memory bandwidth, and implicit-codebook alternatives depend on costly transforms such as Hadamard rotations. The authors propose SCVQ, a post-training…
