Data Processing Skill——把原始数据（CSV/Excel/JSON/爬虫）变成”能直接喂给模型”的干净数据。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Data Processing Skill ## 用途 把原始数据（CSV/Excel/JSON/爬虫）变成"能直接喂给模型"的干净数据。 ## 触发时机 - 拿到赛题自带数据后立刻做 - 爬到的数据入库前做 ## 输入 1. 原始数据文件（`work/data/raw/*.csv` 或 `*.xlsx`） 2. 数据字典（每列什么含义） 3. 分析阶段定的数据需求清单 ## 输出 1. **清洗后数据**（`work/data/clean/*.csv`） 2. **数据质量报告**（`work/data/quality_report.md`） 3. **可视化预览**（`work/figures/data_overview.png`） ## 强制处理流程 ``` 读入（pd.read_csv/excel）→ 概览（head/info/describe）→ 缺失值处理 → 异常值检测 → 标准化/归一化 → 拆分训练/测试 → 导出 ``` ## 缺失值 4 种处理方式 | 场景 | 处理方式 | 代码 | |------|----------|------| | 缺失率 < 5% | 均值/中位数/众数填充 | `df.fillna(df.mean())` | | 缺失率 5-30% | 回归预测填充 | `IterativeImputer` | | 缺失率 > 30% | 删列 or 标记为 "未知" 类别 | `df.drop(columns=...)` | | 时间序列 | 前向/后向填充 | `df.fillna(method='ffill')` | ## 异常值 3 种检测 1. **3σ 原则**：超出均值 ±3 倍标准差 2. **IQR 原则**：超出 Q1-1.5*IQR 或 Q3+1.5*IQR 3. **业务规则**：年龄 < 0、价格 < 0 等明显错误 ## 数据质量报告模板 ```markdown # 数据质量报告 ## 1. 数据规模 - 行数：xxxx - 列数：xx - 内存占用：xx MB ## 2. 缺失值 - 总缺失率：xx% - 缺失率 > 30% 的列：[列名列表] - 处理方式：xxx ## 3. 异常值 - 3σ 检测出 xx 个 - IQR 检测出 xx 个 - 业务规则检测出 xx 个 - 处理方式：xxx ## 4. 分布概览 - 数值型：均值/中位数/标准差/分位数 - 分类型：top 5 类别占比 ``` ## 常用代码片段 ```python import pandas as pd import numpy as np from sklearn.preprocessing import StandardScaler, MinMaxScaler …

How to install
mdr add fourteen1416/academic-agent-toolkit/data-processing@sha256:6929653a6ec26374The line at the top of this page pins the label git:20260923.45cb661, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
