## 方法论
### 分解-组合策略
| 阶段 | 任务 |
|------|------|
| 分解 | HOBC 推断 + 潜在轨迹预测 |
| 组合 | 多尺度拓扑特征 + 高阶信息 |
### 实现框架
```python
import torch
import torch.nn as nn
class DCHOModel(nn.Module):
"""DCHO高阶脑连接预测模型"""
def __init__(self, n_regions=200, latent_dim=64):
super().__init__()
# 双视图编码器
self.local_encoder = nn.Sequential(
nn.Linear(n_regions, 128),
nn.ReLU(),
nn.Linear(128, latent_dim)
)
self.global_encoder = nn.Sequential(
nn.Linear(n_regions * n_regions, 256),
nn.ReLU(),
nn.Linear(256, latent_dim)
)
# 潜在组合学习器
self.combiner = nn.Sequential(
nn.Linear(latent_dim * 2, latent_dim),
nn.ReLU(),
nn.Linear(latent_dim, latent_dim)
)
# 轨迹预测器
self.predictor = nn.LSTM(latent_dim, latent_dim, batch_first=True)
def encode(self, fc_matrix):
"""多尺度编码"""
local_feat = self.local_encoder(fc_matrix.mean(dim=1))
global_feat = self.global_encoder(fc_matrix.flatten())
return self.combiner(torch.cat([local_feat, global_feat], dim=-1))
def predict_trajectory(self, fc_sequence):
"""预测脑动力学轨迹"""
latents = [self.encode(fc) for fc in fc_sequence]
latents = torch.stack(latents, dim=1)
output, _ = self.predictor(latents)
return output
