Use this skill

Your agent runs on

Adds every file the skill has, pinned so you can update it. No account needed.

pip install "decimalai>=0.15"
decimalai skills add leoyeai-automl-skill
claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

The same install from Python, for a notebook or a setup script.

Install

pip install "decimalai>=0.15"

Add the skill

from decimalai import skillpkg

# Writes .agents/skills and .decimal/skills.toml. Safe to run twice.
result = skillpkg.add("leoyeai-automl-skill")
if result.exit_code:
    raise SystemExit(result.problems)

print("Added. Start Claude Code with the command below.")

Start Claude Code with it

claude --plugin-dir "$(git rev-parse --show-toplevel 2>/dev/null || pwd)/.agents"

Type these in a Claude Code session. No account or API key. It writes the skill and any files it bundles, and asks first when its safety rating isn't Passed.

Add the DecimalAI plugin, once

/plugin marketplace add decimal-labs/decimalai-claude-plugins
/plugin install decimalai@decimalai

Install this skill

/decimalai:install leoyeai-automl-skill

The plugin needs python3 and curl on your machine.

No Python or account. Claude Code picks it up in its next session.

Save it into your project

curl -fsSL --create-dirs -o .claude/skills/leoyeai-automl-skill/SKILL.md https://app.decimal.ai/s/leoyeai-automl-skill/SKILL.md

Copy SKILL.md

Save it in your project, as

.claude/skills/leoyeai-automl-skill/SKILL.md

This gets SKILL.md only. The skill's 9 other files are not included.

PyCaret AutoML 技能指南 | PyCaret AutoML Skill Guide

本技能帮助用户使用 PyCaret 快速构建端到端的机器学习工作流。PyCaret 是一个开源的低代码机器学习库，可以将数百行代码简化为几行。

This skill helps users build end-to-end machine learning workflows using PyCaret, an open-source low-code ML library that simplifies hundreds of lines of code into just a few lines.

核心功能 | Core Capabilities

自动化模型选择 - 自动比较多个模型并选择最佳模型
自动化超参数调优 - 使用 Optuna/Hyperopt 自动优化模型参数
自动化特征工程 - 自动进行数据预处理、特征转换和特征选择
模型集成 - 支持 Bagging、Boosting、Stacking、Blending
模型可解释性 - 支持 SHAP、Permutation Importance 等解释方法
模型部署就绪 - 生成可复现的生产级 Pipeline
统计推断增强 - 支持置信区间、假设检验、统计显著性分析

统计推断增强 | Statistical Enhancement (statsmodels)

当需要统计推断、假设检验、置信区间时，可以使用 statsmodels 补充 PyCaret：

线性回归模型

import statsmodels.api as sm

# OLS 回归（带统计显著性）
X = sm.add_constant(X)  # 添加截距
model = sm.OLS(y, X).fit()
print(model.summary())  # R², F检验, P值, 置信区间

广义线性模型 (GLM)

# 二项分布 GLM (Logistic 回归)
glm_model = sm.GLM(y, X, family=sm.families.Binomial()).fit()

# 泊松回归 (计数数据)
poisson_model = sm.GLM(y, X, family=sm.families.Poisson()).fit()

假设检验

from scipy import stats

# t 检验
t_stat, p_value = stats.ttest_ind(group1, group2)

# 卡方检验
chi2, p_value, dof, expected = stats.chi2_contingency(contingency_table)

# ANOVA
f_stat, p_value = stats.f_oneway(*groups)

时间序列分析

from statsmodels.tsa.arima.model import ARIMA
from statsmodels.tsa.statespace.sarimax import SARIMAX

# ARIMA 模型
arima_model = ARIMA(train_data, order=(1,1,1)).fit()
forecast = arima_model.forecast(steps=12)

# 季节性 SARIMAX
sarimax_model = SARIMAX(data, order=(1,1,1), seasonal_order=(1,1,1,12)).fit()

统计诊断

# 残差自相关检验 (Durbin-Watson)
from statsmodels.stats.stattools import durbin_watson
dw = durbin_watson(model.resid)

# 异方差检验
from statsmodels.stats.diagnostic import het_breuschpagan
bp_test = het_breuschpagan(model.resid, model.model.exog)

# 正态性检验
from scipy import stats
shapiro_stat, shapiro_p = stats.shapiro(model.resid)

混合效应模型 (随机效应)

# 混合线性模型 (Panel Data / 多层次数据)
from statsmodels.regression.mixed_linear_model import MixedLM
mixed_model = MixedLM(y, X, groups=group_var).fit()

PyCaret + statsmodels 组合使用

# 1. 用 PyCaret 快速建模和选择模型
from pycaret.classification import *
clf = setup(data, target='target')
best = compare_models()
tuned = tune_model(best)

# 2. 用 statsmodels 做统计推断
import statsmodels.api as sm
# 获取 PyCaret 模型的特征和预测
X_with_const = sm.add_constant(X_test)
sm_model = sm.Logit(y_test, X_with_const).fit(disp=0)
print(sm_model.summary())  # 系数显著性 P值

购物篮分析 → 使用 pycaret.arules

2. 标准 AutoML 工作流 | Standard AutoML Workflow

完整的 AutoML 工作流程包含以下步骤：

Step 1: 数据收集与加载 | Data Collection & Loading

# 数据加载
import pandas as pd
train = pd.read_csv('train.csv')
test = pd.read_csv('test.csv')

# 或使用 PyCaret 内置数据集
from pycaret.classification import get_data
data = get_data('breast_cancer')

Step 2: 数据理解与探索 | Data Understanding & EDA

# 基本信息
print(f"数据形状: {data.shape}")
print(f"数据类型:\n{data.dtypes}")

# 缺失值分析
missing = data.isnull().sum()
missing_pct = (missing / len(data) * 100).round(2)
print(f"缺失值比例:\n{pd.concat([missing, missing_pct], axis=1)}")

# 目标变量分布
data['target'].value_counts()

# 数值特征统计
data.describe()

Step 3: 数据预处理 | Data Preprocessing (setup 中自动完成)

# 初始化环境 - 数据预处理配置
clf = setup(
    data,
    target='target',

    # ===== 缺失值处理 =====
    numeric_imputation='mean',       # 数值型: mean/median/mode/knn/iterative
    categorical_imputation='mode',   # 类别型: mode/constant

    # ===== 异常值处理 =====
    remove_outliers=True,           # 移除异常值
    outliers_method='iforest',      # iforest/ee/lof
    outliers_threshold=0.05,        # 异常值比例

    # ===== 类别不平衡处理 =====
    fix_imbalance=True,             # 处理类别不平衡
    fix_imbalance_method='SMOTE',  # SMOTE/ADASYN/RandomOverSampler

    # ===== 数据类型指定 =====
    numeric_features=['age', 'income', 'score'],
    categorical_features=['city', 'gender', 'occupation'],
    date_features=['Date', 'created_at'],

    session_id=42
)

Step 4: 特征工程 | Feature Engineering (setup 中自动完成)

clf = setup(
    data,
    target='target',

    # ===== 特征缩放 =====
    normalize=True,                 # 归一化
    normalize_method='zscore',     # zscore/minmax/maxabs/robust

    # ===== 特征变换 =====
    transformation=True,            # 变换使数据更接近正态分布
    transformation_method='yeo-johnson',  # yeo-johnson/quantile

    # ===== 特征选择 =====
    feature_selection=True,         # 特征选择
    feature_selection_method='classic',      # classic/univariate/sequential
    n_features_to_select=0.2,     # 选择20%最重要特征

    # ===== 降维 =====
    pca=True,                      # PCA降维
    pca_method='linear',           # linear/kernel/incremental
    pca_components=0.95,           # 保留95%方差

    # ===== 多重共线性处理 =====
    remove_multicollinearity=True,
    multicollinearity_threshold=0.9,

    # ===== 特征编码 =====
    ordinal_features={'education': ['high_school', 'bachelor', 'master', 'phd']},
    high_cardinality_features='frequency',  # 处理高基数类别特征

    # ===== 特征交互 =====
    polynomial_features=True,
    polynomial_degree=2,

    # ===== 分箱（离散化） =====
    bin_numeric_features=['age', 'income'],

    session_id=42
)

Step 5: 模型选择 | Model Selection

# 比较所有模型
best_model = compare_models()

# 指定模型列表比较
best_model = compare_models(include=['lr', 'rf', 'xgboost', 'catboost', 'lightgbm'])

# 快速模式（排除耗时模型）
best_model = compare_models(turbo=True)

# 按特定指标排序
best_model = compare_models(sort='F1')  # 对于不平衡数据

Step 6: 模型训练 | Model Training

# 创建模型
model = create_model('rf')

# 指定模型参数
model = create_model('xgboost', n_estimators=100, max_depth=5)

Step 7: 超参数调优 | Hyperparameter Tuning

# 自动调优
tuned_model = tune_model(model)

# 自定义调优
tuned_model = tune_model(
    model,
    custom_grid={
        'n_estimators': [100, 200, 300],
        'max_depth': [3, 5, 7, None],
        'learning_rate': [0.01, 0.1, 0.3]
    },
    optimize='Accuracy',           # 分类: Accuracy/AUC/Recall/Precision/F1/MCC
                                  # 回归: RMSE/MSE/MAE/R2/RMSLE/MAPE
    choose_better=True,            # 返回更好的模型
    n_iter=50                      # 迭代次数
)

Step 8: 模型评估 | Model Evaluation

# 交互式评估
evaluate_model(tuned_model)

# 各种评估图表
plot_model(tuned_model, plot='auc')                # ROC曲线
plot_model(tuned_model, plot='confusion_matrix')   # 混淆矩阵
plot_model(tuned_model, plot='classification_report')  # 分类报告
plot_model(tuned_model, plot='learning_curve')    # 学习曲线
plot_model(tuned_model, plot='feature')            # 特征重要性
plot_model(tuned_model, plot='residuals')          # 残差图（回归）
plot_model(tuned_model, plot='error')              # 预测误差

# 交叉验证结果
results = pull()  # 获取当前实验结果

Step 9: 模型解释 | Model Interpretation

# SHAP 解释
interpret_model(tuned_model)

# Permutation Importance
interpret_model(tuned_model, plot='correlation')

# 局部解释
interpret_model(tuned_model, plot='reason', observation=0)

Step 10: 模型集成 | Model Ensemble

# Bagging
bagged = ensemble_model(tuned_model, method='Bagging')

# Boosting
boosted = ensemble_model(tuned_model, method='Boosting')

# 融合多个模型
blended = blend_models(
    estimator_list=['lr', 'dt', 'rf', 'xgboost'],
    method='soft',                  # soft/hard
    weights=[1, 2, 3, 2]           # 各模型权重
)

# 堆叠
stacked = stack_models(
    estimator_list=['lr', 'dt', 'rf'],
    meta_model='xgboost',
    restack=False                   # 是否允许基础模型使用原始特征
)

Step 11: 最终模型训练与预测 | Final Model Training & Prediction

# 在全部数据上训练最终模型
final_model = finalize_model(tuned_model)

# 预测
predictions = predict_model(final_model, data=test)

# 预测概率（分类）
predictions = predict_model(
    final_model,
    data=test,
    probability_threshold=0.7       # 自定义阈值
)

Step 12: 模型保存与部署 | Model Save & Deployment

# 保存模型（包含完整Pipeline）
save_model(final_model, 'my_model')

# 保存实验配置
save_experiment('my_experiment')

# 加载模型
loaded_model = load_model('my_model')

# 部署到云平台
deploy_model(
    final_model,
    platform='aws',                 # aws/gcp/azure
    authentication={
        'bucket': 'my-bucket'
    }
)

# 创建Web应用
create_app(final_model, app_path='app.py')

# 创建REST API
create_api(final_model, api_name='predict', api_file='predict.py')

# 创建Docker
create_docker('my_model', docker_path='Dockerfile')
