Garbage classification using structure data.

Overview

垃圾分类模型使用说明

1.包含以下数据文件

文件 描述
data/MaterialMapping.csv 物体以及其归类的信息
data/TestRecords 光谱原始测试数据 CSV 文件
data/TestRecordDesc.zip CSV 文件描述文件
data/Boundaries.csv 物体轮廓信息

2.包含以下模型文件

文件夹 描述
output/Category/ 包含预测大类别的分类模型
output/Material/ 包含预测大类别(4类)的分类模型
output/Backgroud/ 包含预测小类别(50类)的分类模型

3.环境配置

  进入garbage路径,在anaconda命令行运行pip install -r requirements.txt

4.数据预处理

  在anaconda命令行运行python data_preprocess.py,即可在data文件夹中生成AllEmbracingDataset.csv。若将来更新数据,按照和原来相同的格式和路径保存在data文件夹中,即可用data_preprocess.py生成更新后的数据集

  • 运行数据预处理Python脚本,将上述数据的信息集合到一个数据文件中
python code/data_preprocess.py -data_dir D:/datasets/garbage \
                        -test \
                        -groupbyObjID

运行脚本生成的数据文件 datasets/AllEmbracingDataset.csv 数据集

5.模型训练Python脚本

python code/train_gbdt_lr.py -data_dir D:/datasets/garbage/ \
                    -use_groupbyID True \
                    -output_dir output/ \
                    -skip_data_preprocess

其他 Python脚本说明:

  • feature_engineering.py 特征工程代码
  • ref.py 数据处理和模型推理所需的配置文件
  • utils.py 数据处理所需的一些函数
  • gbdt_feature.py 用gbdt模型生成特征

6.模型推理Python脚本

python code/predict_gbdt_lr.py -data_dir D:/datasets/garbage/ \
                    -use_groupbyID True \
                    -output_dir output/ \
                    -skip_data_preprocess \
                    -save_dir output/ 

  注1:只要同一个ObjID的多条数据的预测结果有一个不是背景零,最终预测结果就不是背景零。

  注2:预测出的Material只会是在训练数据中出现过的唯一标记号。这次数据中不同的唯一标记号共有148个,具体可参见output/log/log.txt中的LabelEncoder.classes

  • 预测结果文件(predictions.csv)说明:对每个物体(即每个ObjID,通常对应多条测试记录)给出多个预测结果汇总后的预测结果。
# 域名 意义
1 ObjID 被测物体唯一标记。同一物体会对应多条测试记录
2 Category 物体分类,从训练数据中获取
3 Material 物体对应的唯一标识号,从训练数据中获取
4 pred_Category 模型所预测出的物体分类
5 pred_Material 模型所预测出的物体唯一标识号
6 pred_background 模型预测的背景和物体 (背景标记为 0,物体标记为 1)
7 pred_Category_final 模型所预测出的物体分类
8 pred_Material_final 模型所预测出的物体材料分类

7. 模型精度

  对于Category、Material和Background三种场景的预测,我们均使用GBDT+LR模型。尝试过SVM、XGBoost、LightGBM和GBDT+LR模型,对比之下,GBDT+LR模型表现最好。   在测试集上的Accuracy如下:

场景 Accuracy
Category 0.7583130575831306
Material 0.6042173560421735
Background 0.996044825313118
