# Two-Fold Inference Paradigm (双折推断范式)
|
||||
|
||||
SMG 的核心架构创新——将过参数化系统中的推断**正交分裂**为两个互不干扰的操作域。
|
||||
|
||||
## 第一折:水平统计推断(Horizontal Statistical Inference)
|
||||
|
||||
- **空间**:基流形 B,即 [[statistically-verifiable-directions|SVDχ]] 方向
|
||||
- **工具**:经典统计——MLE、贝叶斯后验更新、最小对比度方法
|
||||
- **Fisher 度量**:严格正定,非退化
|
||||
- **语义**:由数据驱动、可经验证伪的假设检验
|
||||
|
||||
## 第二折:垂直几何推断(Vertical Geometric Inference)
|
||||
|
||||
- **空间**:纤维 Fb,即 [[structural-internal-directions|SID]] 方向
|
||||
- **工具**:纯微分拓扑——[[ehresmann-connection-filtering|Ehresmann 联络]]、平行移动
|
||||
- **一阶方差**:严格为零(统计工具完全盲化)
|
||||
- **语义**:内部自由度路由、损失景观平滑、优化热浴
|
||||
|
||||
## 正交合成(Orthogonal Synthesis)

## 关键保证
|

|
||||
Cheng-Tong 正交度量分解证明:水平统计引擎和垂直拓扑引擎**永不互相污染**——这是过参数化系统的安全运转前提。
