# Native Streaming AR Training (原生流式自回归训练)

**Native Streaming AR Training** 是 [[maineCoon|MaineCoon]] 的核心训练范式：在训练和推理时使用**相同的因果逐块自回归 regime**，而非通过 teacher forcing 从非因果教师蒸馏。

## 核心原则

- **Chunk-by-chunk causal rollout**：每次预测一个 chunk，仅以已生成的 chunk 为条件
- **无 Teacher Forcing**：不从双向教师蒸馏流式行为——原生即流式
- **Train-inference matched**：训练和推理分布一致，消除 gap

## 关键组件

- [[self-resampling|Self-Resampling]]：以模型自身退化历史为条件
- [[flow-matching|Flow Matching]] loss
- [[audio-visual-representation-alignment|Cross-Modal Representation Alignment]] 加速
