1. 简介
本项目使用 Hepatitis C（丙型肝炎）血液检测数据集，根据年龄、性别及多项生化指标预测受试者类别。实验先以随机森林建立基线模型，再利用 PyTorch 搭建单层 LSTM 网络完成五分类，并使用 Optuna 搜索合适的超参数。
| 项目 | 内容 |
|---|---|
| 模型 | RandomForestRegressor（基线）+ 单层 LSTM |
| 任务 | 五分类：Blood Donor / suspect Blood Donor / Hepatitis / Fibrosis / Cirrhosis |
| 数据集 | 615 条记录、12 个特征；训练集 492 条、测试集 123 条 |
| 最佳参数 | hidden_size=192，lr=2.282961835545562e-05 |
| 测试结果 | 随机森林准确率 89%；LSTM 第 50 轮测试准确率约 88.6% |
2. 环境
- 语言环境：Python（
.venv312） - 编译器：Jupyter Notebook
- 深度学习环境：PyTorch
- 主要库：pandas、scikit-learn、matplotlib、seaborn、torchinfo、Optuna
- 运行设备：CPU（Notebook 输出为
device(type='cpu')）
3. 代码实现
3.1 前期准备
3.1.1 导入库与设置设备
python
import pandas as pd
import torch
import torch.utils.data as data
import matplotlib.pyplot as plt
import seaborn as sns
from torch import nn
from sklearn.preprocessing import LabelEncoder, StandardScaler
from sklearn.model_selection import train_test_split
from sklearn.ensemble import RandomForestRegressor
from sklearn.metrics import classification_report
from torch.utils.data import DataLoader
from torchinfo import summary
import numpy as np
import optuna
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
print(device)
bash
device(type='cpu')3.1.2 数据读取与标签编码
数据集位于 ./Data/HepatitisCdata.csv，共有 615 条记录。Category 和 Sex 为字符串类型，使用 LabelEncoder 编码；第一列是样本编号，因此删除。
python
df = pd.read_csv('./Data/HepatitisCdata.csv')
le = LabelEncoder()
df["Category"] = le.fit_transform(df["Category"])
df["Sex"] = le.fit_transform(df["Sex"])
df = df.iloc[:, 1:]
df.head()
处理后数据有 13 列：Category 为标签，其余 12 列为输入特征，分别是 Age、Sex、ALB、ALP、ALT、AST、BIL、CHE、CHOL、CREA、GGT 和 PROT。
3.1.3 相关性分析与缺失值处理
使用相关性热力图观察特征间关系，再检查缺失值。ALB、ALP、ALT、CHOL 和 PROT 存在缺失值，Notebook 将它们填充为 0。
python
numeric_cols = df.select_dtypes(include=['int64', 'float64'])
plt.figure(figsize=(12, 8))
sns.heatmap(numeric_cols.corr(), cmap='coolwarm', annot=True)
plt.title("Correlation Heatmap")
plt.show()
python
df.isnull().any()
bash

y = df.iloc[:, 0]
X_train, X_test, y_train, y_test = train_test_split(
X, y, test_size=0.2, random_state=123
)
print(y_train.shape, y_test.shape)
bash
(492,) (123,)数据按照 8:2 划分，获得 492 条训练样本和 123 条测试样本。
3.2 随机森林基线模型
3.2.1 特征重要性
在搭建 LSTM 前，先训练 100 棵树的随机森林作为基线，并查看特征重要性。
python
rf = RandomForestRegressor(n_estimators=100, random_state=42)
rf.fit(X_train, y_train)
feature_importance = pd.DataFrame({
'feature': X_train.columns,
'importance': rf.feature_importances_
}).sort_values('importance', ascending=False)
print(feature_importance.head(3))
bash
feature importance
5 AST 0.604564
4 ALT 0.133625
3 ALP 0.085247AST 的重要性明显最高，其次为 ALT 和 ALP，说明这三项肝功能相关指标在当前随机森林模型中具有较强区分能力。
3.2.2 基线结果
python
y_pred_rf = rf.predict(X_test)
y_pred_rf_class = np.round(y_pred_rf)
print(classification_report(y_test, y_pred_rf_class))
bash

3.3 LSTM 模型建立与训练
3.3.1 数据标准化与加载
LSTM 对特征尺度较敏感，先在训练集上拟合 StandardScaler，再转换测试集。unsqueeze(1) 将每条记录转化为 (batch_size, 1, 12) 的三维输入。
python
sc = StandardScaler()
X_train = sc.fit_transform(X_train)
X_test = sc.transform(X_test)
X_train = torch.tensor(X_train, dtype=torch.float32).unsqueeze(1)
X_test = torch.tensor(X_test, dtype=torch.float32).unsqueeze(1)
y_train = torch.tensor(y_train.values, dtype=torch.int64)
y_test = torch.tensor(y_test.values, dtype=torch.int64)
batch_size = 32
train_dataset = data.TensorDataset(X_train, y_train)
test_dataset = data.TensorDataset(X_test, y_test)
train_dataloader = DataLoader(train_dataset, batch_size=batch_size, shuffle=True)
test_dataloader = DataLoader(test_dataset, batch_size=batch_size)
print(X_train.shape, X_test.shape, y_train.shape, y_test.shape)
bash
torch.Size([492, 1, 12])
torch.Size([123, 1, 12])
torch.Size([492])
torch.Size([123])3.3.2 定义 LSTM 网络模型
模型由一个单层 LSTM 和一个五分类全连接层组成。LSTM 提取最后一个时间步的隐藏状态，再通过线性层输出各类别的预测分数。
python
class model_lstm(nn.Module):
def __init__(self, hidden_size=200):
super(model_lstm, self).__init__()
self.lstm0 = nn.LSTM(
input_size=12, hidden_size=hidden_size,
num_layers=1, batch_first=True
)
self.fc0 = nn.Linear(hidden_size, 5)
def forward(self, x):
out, _ = self.lstm0(x)
out = out[:, -1, :]
return self.fc0(out)
model = model_lstm(hidden_size=200)
summary(model, (64, 1, 12))
bash

训练函数执行前向传播、损失计算、反向传播与参数更新；测试函数在 torch.no_grad() 下只计算准确率和损失。
python
def train(dataloader, model, loss_fn, optimizer):
size = len(dataloader.dataset)
num_batches = len(dataloader)
train_loss, train_acc = 0, 0
for X, y in dataloader:
X, y = X.to(device), y.to(device)
pred = model(X)
loss = loss_fn(pred, y)
optimizer.zero_grad()
loss.backward()
optimizer.step()
train_acc += (pred.argmax(1) == y).float().sum().item()
train_loss += loss.item()
return train_acc / size, train_loss / num_batches
def test(dataloader, model, loss_fn):
size = len(dataloader.dataset)
num_batches = len(dataloader)
test_loss, test_acc = 0, 0
with torch.no_grad():
for X, y in dataloader:
X, y = X.to(device), y.to(device)
pred = model(X)
test_loss += loss_fn(pred, y).item()
test_acc += (pred.argmax(1) == y).float().sum().item()
return test_acc / size, test_loss / num_batches3.3.4 Optuna 超参数搜索
在 hidden_size=128、192、256 和学习率 1e-5 到 1e-4 的范围内进行 20 次试验，以测试损失最小作为目标。
python
def objective(trial):
hidden_size = trial.suggest_int("hidden_size", 128, 256, step=64)
lr = trial.suggest_loguniform("lr", 1e-5, 1e-4)
model = model_lstm(hidden_size=hidden_size)
loss_fn = nn.CrossEntropyLoss()
optimizer = torch.optim.Adam(model.parameters(), lr=lr)
train(train_dataloader, model, loss_fn, optimizer)
_, epoch_test_loss = test(test_dataloader, model, loss_fn)
return epoch_test_loss
study = optuna.create_study(direction="minimize")
study.optimize(objective, n_trials=20)
print("最佳超参数：", study.best_params)
bash
最佳超参数： {'hidden_size': 192, 'lr': 2.282961835545562e-05}3.3.5 训练模型
使用交叉熵损失函数和 Adam 优化器，依据最佳超参数训练 50 个 Epoch。
python
loss_fn = nn.CrossEntropyLoss()
learn_rate = 2.282961835545562e-05
model = model_lstm(hidden_size=192).to(device)
opt = torch.optim.Adam(model.parameters(), lr=learn_rate)
epochs = 50
train_loss, train_acc = [], []
test_loss, test_acc = [], []
for epoch in range(epochs):
model.train()
epoch_train_acc, epoch_train_loss = train(train_dataloader, model, loss_fn, opt)
model.eval()
epoch_test_acc, epoch_test_loss = test(test_dataloader, model, loss_fn)
train_acc.append(epoch_train_acc)
train_loss.append(epoch_train_loss)
test_acc.append(epoch_test_acc)
test_loss.append(epoch_test_loss)Notebook 原始训练日志的格式标签存在错位：显示为 Test_loss 的数字实际是测试准确率（百分比），显示为 Lr 的数字实际是测试损失。根据变量真实含义，关键训练结果应解读为：
bash
Epoch: 1, Train_acc: 53.3%, Train_loss: 1.576, Test_acc: 58.5%, Test_loss: ≈1.58
Epoch: 10, Train_acc: 88.6%, Train_loss: 1.548, Test_acc: 82.9%, Test_loss: ≈1.55
Epoch: 26, Train_acc: 90.7%, Train_loss: 1.494, Test_acc: 86.2%, Test_loss: ≈1.50
Epoch: 50, Train_acc: 92.1%, Train_loss: 1.387, Test_acc: 88.6%, Test_loss: ≈1.404. 模型评估
4.1 可视化训练过程
python
epochs_range = range(epochs)
plt.figure(figsize=(12, 3))
plt.subplot(1, 2, 1)
plt.plot(epochs_range, train_acc, label="Training Accuracy")
plt.plot(epochs_range, test_acc, label="Test Accuracy")
plt.legend(loc='lower right')
plt.title('Training and Validation Accuracy')
plt.subplot(1, 2, 2)
plt.plot(epochs_range, train_loss, label="Training Loss")
plt.plot(epochs_range, test_loss, label="Test Loss")
plt.legend(loc='upper right')
plt.title('Training and Validation Loss')
plt.show()
训练准确率由 53.3% 提升至 92.1%，测试准确率由 58.5% 提升至约 88.6%。训练集与测试集之间存在一定差距，但测试集表现整体随训练过程提高。
4.2 模型结果对比
| 模型 | 测试准确率 | 说明 |
|---|---|---|
| 随机森林基线 | 89.0% | AST、ALT、ALP 的重要性较高 |
| 单层 LSTM | 约 88.6% | hidden_size=192，训练 50 Epoch |
两个模型整体表现接近，随机森林略高。由于每个样本被整理为长度为 1 的序列，LSTM 并没有可利用的真实时序信息，因而在该静态表格数据上未体现出显著优势。
5. 总结
- 本实验完成了 Hepatitis C 血液检测数据的五分类，包括数据编码、缺失值处理、随机森林基线和 LSTM 建模。
- 随机森林测试准确率为 89% ；AST 的特征重要性最高，为 0.604564。
- Optuna 搜得 LSTM 的最佳参数为
hidden_size=192、lr≈2.28e-05。训练 50 个 Epoch 后，训练准确率达到 92.1% ，测试准确率约为 88.6%。 - 类别分布高度不均衡，不能仅以总体准确率衡量模型效果；后续可补充混淆矩阵、宏平均 F1、类别权重、SMOTE 和分层交叉验证。
- 若未来拥有同一患者多次检测的连续数据，可进一步构建真正的时间序列；对于当前静态表格数据，也可尝试
RandomForestClassifier、XGBoost 或 MLP 等模型。
