+## 项目特点
+
+- **四类垃圾分类**：厨余垃圾（1）、可回收物（2）、其他垃圾（3）、有害垃圾（4）
+- **ResNet-34 架构**：约 21M 参数，34 层深度残差网络，含 Dropout 正则化
+- **数据增强**：训练时使用随机裁剪、水平翻转、旋转、色彩抖动
+- **Macro-F1 评估**：采用宏平均 F1 分数作为主要评估指标，兼顾各类别表现
+- **类别加权损失**：自动计算类别权重，缓解类别不平衡问题
+- **余弦退火学习率调度**：使用 CosineAnnealingLR 平滑调整学习率
+- **断点续训**：自动检测 `best_model.pth` 并加载继续训练
+- **多设备支持**：自动选择 CUDA > Intel XPU > CPU
+
+## 模型架构
+
+模型基于标准 ResNet-34 架构，使用 BasicBlock 构建。
+
+### BasicBlock 块
+
+每个 BasicBlock 包含两个 3x3 卷积层 + 跳跃连接：
+
+| 层 | 卷积 | 作用 |
+|---|---|---|
+| 3x3 Conv | 特征提取 | 第一层卷积 |
+| 3x3 Conv | 特征提取 | 第二层卷积 |
+
+### 网络结构
+
+| 阶段 | 块数 | 输出通道数 | 说明 |
+|---|---|---|---|
+| 初始层 | - | 64 | 7x7 Conv, stride=2 + MaxPool |
+| Layer1 | 3 | 64 | 第一个残差阶段 |
+| Layer2 | 4 | 128 | - |
+| Layer3 | 6 | 256 | - |
+| Layer4 | 3 | 512 | 最终残差阶段 |
+| 分类头 | - | 4 | 全局平均池化 + Dropout + 全连接层 |
+
+## 数据集
+
+本项目使用 [tany0699/garbage265](https://modelscope.cn/datasets/tany0699/garbage265) 中文生活垃圾分类数据集，包含 265 个子类别的生活垃圾图片。
+
+通过 `Merge_classes.py` 脚本将 265 个子类别合并为 4 个顶级类别：
+
+```
+厨余垃圾 -> 1
+可回收物 -> 2
+其他垃圾 -> 3
+有害垃圾 -> 4
+```
+
+数据集预期放置在 `../trash_division_data/`（与项目根目录平级的兄弟目录）。
+
+## 环境要求
+
+```bash
+pip install -r requirements.txt
+```
+
+> **注意**：`requirements.txt` 不锁定 PyTorch 的 CUDA / XPU 版本，请根据硬件自行安装对应版本，例如：
+> - NVIDIA GPU：`pip install torch torchvision --index-url https://download.pytorch.org/whl/cu121`
+> - Intel GPU (XPU)：`pip install torch torchvision --index-url https://download.pytorch.org/whl/xpu` 安装
+> - CPU：`pip install torch torchvision` 即可
+
+## 快速开始
+
+1. **数据预处理**：将 265 个子类别合并为 4 个顶级类别
+
+   ```bash
+   python Merge_classes.py
+   ```
+
+2. **训练模型**：
+
+   ```bash
+   python Train.py
+   ```
+
+3. **微调模型**（可选，冻结浅层、微调深层）：
+
+   ```bash
+   python Finetune.py
+   ```
+
+4. **评估与可视化**：
+
+   ```bash
+   python Evaluate.py                  # 混淆矩阵、ROC 曲线、PR 曲线
+   python Curve.py                     # 训练过程的 loss/f1/acc/lr 曲线
+   python baseline/compare_models.py   # 多模型基线对比（ROC/PR/准确率）
+   ```
+
+> **注意**：
+> - 数据目录默认为 `../trash_division_data/ultimate_4_class/`，需先运行合并脚本
+> - Windows 系统需将 `num_workers` 设为 `0`（参见 `Dataloader.py` 和 `Train.py`）
+> - 训练会自动从 `best_model.pth` 断点续训（若存在）
+

+## 训练细节
+
+| 配置项 | 说明 |
+|---|---|
+| 输入尺寸 | 256 x 256 RGB |
+| 优化器 | SGD（momentum=0.9, weight_decay=1e-4） |
+| 初始学习率 | 0.001 |
+| 学习率调度 | CosineAnnealingLR |
+| 损失函数 | 类别加权 CrossEntropyLoss |
+| 评估指标 | Macro-F1（宏平均 F1 分数） |
+| 批量大小 | 默认 16（可通过参数调整） |
+| 训练轮数 | 默认 20（可通过参数调整） |
+| 设备选择优先级 | CUDA > Intel XPU > CPU |
+| 断点续训 | 自动检测 best_model.pth 并加载 |
+
+训练时数据增强管线：RandomResizedCrop(256, scale=(0.8, 1.0)) + RandomHorizontalFlip(p=0.5) + RandomRotation(+-15 deg) + ColorJitter(brightness=0.2, contrast=0.2, saturation=0.2)
+
+## 评估与可视化
+
+训练完成后，`training_log.csv` 会记录每个 epoch 的训练/验证指标。以下两个脚本用于可视化分析：
+
+### Evaluate.py — 模型评估
+
+在验证集上推理，生成三张评估图表：
+
+```bash
+python Evaluate.py
+```
+
+脚本顶部的 `MODEL_PATH`、`DATA_ROOT`、`BATCH_SIZE`、`NUM_WORKERS` 可按需修改。
+
+**混淆矩阵**
+
+![confusion_matrix](confusion_matrix.png)
+
+**ROC 曲线**
+
+![roc_curve](roc_curve.png)
+
+**PR 曲线**
+
+![pr_curve](pr_curve.png)
+
+### Curve.py — 训练曲线
+
+从 `training_log.csv` 读取训练日志，绘制四张子图：
+
+```bash
+python Curve.py
+```
+
+![training_curves](training_curves.png)
+
+### 基线模型对比
+
+`compare_models.py` 对所有模型在验证集上统一评估，生成三张对比图表：
+
+```bash
+python baseline/compare_models.py
+```
+
+对比阵容：ResNet-34、ResNet-34 (10% Fine-tune)、VGG16 + KNN、HOG + LogisticRegression。
+
+**ROC 曲线对比**
+
+![roc_comparison](baseline/roc_comparison.png)
