QuantMLA: Function-Aligned Dual-Path Quantization for Low-Bit MLA KV Caching

Multi-Head Latent Attention (MLA) enables expressive multi-head attention with compact caches for its content and decoupled RoPE paths, yet cache memory still scales linearly with context length and batch size. In this work, we establish a systematic model of MLA's dual-path quantization errors, characterizing their di...

Beyond Teacher Assignment: Domain-Normalized Multi-Teacher On-Policy Distillation

Domain-Normalized MOPD is proposed, which keeps the routing and rescales each domain's feedback by its measured spread, and improves the average score over MOPD at every size, across three random seeds and under two answer-length limits, and recovers most of the lost mathematics gain.

DASC: Decay-Aware State Compression for Hybrid Linear-Attention Serving

Decay-Aware State Compression (DASC), which derives retention horizons from model weights, selects long-horizon state units, and packs them into a ragged state checkpoint layout to integrate efficiently with tensor-parallel inference engines.

DAMP: Decay-Aware Mixed-Precision Recurrent-State Quantization

DAMP uses both quantization-error energy and decay-based persistence to identify high-risk channels during offline calibration and stores these channels at higher precision and the remainder in INT8, the first to study post-training quantization of recurrent states in GDN and KDA based language models.
