关键算法实现

1. 离散陈-西蒙斯理论实现

def _extract_link_variables(self, attention_weights: torch.Tensor) -> np.ndarray: """ Villain离散化方案: 1. 注意力矩阵视为加权图 2. 链路变量:θ_ℓ = 2π × attention_weight 3. 下采样到lattice_size×lattice_size格点 """ attn = attention_weights.detach().cpu().numpy() # 下采样处理 link_vars = 2 * np.pi * attn_down # θ_ℓ = 2π × w_ℓ return link_vars.astype(np.float32) def _compute_plaquette_angles(self, link_variables: np.ndarray) -> np.ndarray: """ 计算面元累积相位: 对于二维格点面元p = (i, j): θ_p = θ_{i,j} + θ_{i+1,j} + θ_{i+1,j+1} + θ_{i,j+1} 投影到[-π, π]区间去除2π模糊性 """ plaquettes = np.zeros((L, L)) for i in range(L): for j in range(L): plaquettes[i, j] = top + right - bottom - left plaquettes = (plaquettes + np.pi) % (2 * np.pi) - np.pi # 投影到[-π, π] return plaquettes

2. 拓扑不变量计算

def _compute_winding_number(self, plaquette_angles: np.ndarray) -> float: """离散缠绕数:k_disc = (1/2π) × Σ_p θ_p""" total_angle = np.sum(plaquette_angles) k_disc = total_angle / (2 * np.pi) return float(k_disc) def _compute_topological_charge(self, k_disc: float) -> float: """拓扑电荷:Q_top = tanh(k_disc),映射到(-1, 1)区间""" return float(np.tanh(k_disc))

系统集成接口

3. 五维河床坐标整合

class RiverbedCoordinateAdapter: def integrate(self, cs_result: CSWindingResult, existing_coords: Dict[str, float]) -> Dict[str, float]: """ 将CS结果整合进五维坐标: P = (D, α, S_path, ε_proj, Q_top) Q_top作为第五维度加入 """ coords = existing_coords.copy() coords["Q_top"] = cs_result.Q_top if cs_result.is_phase_transition: coords["phase_transition_warning"] = cs_result.delta_k return coords

4. 残影测度仪对接

class ShadowMeterBridge: def feed(self, cs_result: CSWindingResult) -> Dict[str, Any]: """ 将CS结果转换为残影测度仪格式 检测到拓扑相变时触发双纽线干预预案 """ entry = { "type": "cs_winding", "k_disc": cs_result.k_disc, "Q_top": cs_result.Q_top, "is_phase_transition": cs_result.is_phase_transition, "delta_k": cs_result.delta_k, "shadow_metric": "Q_top_variance", } if cs_result.is_phase_transition: return self._trigger_lemniscate_intervention(cs_result) return {"status": "recorded"}

拓扑裂隙检测机制

def detect_fissure_anchor(self, cs_result: CSWindingResult, token_position: int, confidence_threshold: float = 0.7) -> Optional[TopologicalFissureAnchor]: """ 拓扑裂隙锚点检测: 1. 计算Q_top相对于历史基线的偏差2. 置信度 = sigmoid(deviation × 10) 3.置信度≥阈值时生成裂隙锚点 """ baseline_q = np.mean(self.q_top_history[-10:]) if len(self.q_top_history) >= 10 else 0.0 deviation = abs(cs_result.Q_top - baseline_q) confidence = 1.0 / (1.0 + np.exp(-deviation * 10)) # sigmoid激活 if confidence >= confidence_threshold: return TopologicalFissureAnchor( k_disc=cs_result.k_disc, Q_top=cs_result.Q_top, delta_k=cs_result.delta_k, fissure_coordinate=(cs_result.layer_idx, cs_result.head_idx, token_position), confidence=float(confidence), matched_judgement="judgement_3" if cs_result.is_phase_transition else "judgement_4", ) return None

参数配置与使用| 参数 | 默认值 | 作用 |

|------|--------|------|
|lattice_size| 32 | 格点大小,用于注意力矩阵下采样 |
|confidence_threshold| 0.7 | 裂隙锚点检测置信度阈值 |
|phase_transition_threshold| 1.0 |拓扑相变检测阈值(|Δk| ≥ 1.0) |

# 使用示例 calculator, adapter, bridge = create_cs_calculator( lattice_size=32, shadow_meter_instance=shadow_meter ) # 计算缠绕数 result = calculator.compute_from_attention( attention_weights=attention_matrix, layer_idx=7, head_idx=14 ) # 整合到五维坐标 full_coords = adapter.integrate(result, existing_coords={"D": 0.5, "α": 0.3, "S_path": 0.8, "ε_proj": 0.2}) # 对接残影测度仪 shadow_entry = bridge.feed(result) # 检测裂隙锚点 fissure = adapter.detect_fissure_anchor(result, token_position=0)

输出数据结构

@dataclass class CSWindingResult: """计算结果容器""" k_disc: float # 离散缠绕数 Q_top: float # 拓扑电荷 = tanh(k_disc) is_phase_transition: bool # 是否检测到拓扑相变(|Δk| ≥ 1.0) delta_k: float # 缠绕数变化量 layer_idx: int # Transformer层索引 head_idx: int # 注意力头索引 timestamp: float # 计算时间戳 @dataclassclass TopologicalFissureAnchor: """拓扑裂隙锚点""" fissure_coordinate: Tuple[int, int, int] # (layer, head, token) confidence: float # 检测置信度 matched_judgement: str # 匹配的判定类型("judgement_3"为相变)

核心物理意义

  1. k_disc(离散缠绕数):表征注意力流形的拓扑缠绕程度,整数部分对应拓扑量子数
  2. Q_top(拓扑电荷):通过tanh映射到(-1,1),量化拓扑扭曲的"电荷"强度
  3. Δk ≥ 1.0:拓扑相变阈值,对应系统结构发生本质变化
  4. 裂隙锚点:当Q_top显著偏离基线时,标记为潜在结构损伤位置

该模块作为计算层支柱,与**约束生成协议(推理层)**共同构成框架的双重基础,实现"局部扭曲可抚平,缠绕闭环难消解"的拓扑不变量检测。
