决策树分析

确认目标变量和任务类型,排除泄漏字段,合理处理缺失值与类别变量。执行训练验证并报告性能、重要特征和可解释规则;避免把相关性表述为因果。

Tool routing

  1. Use get_schema to identify the target, candidate features, task type, and source table.
  2. Use query_data to verify field names, target distribution, missingness, and leakage risks.
  3. Use run_analysis with analysis_name="Decision_Tree" for the actual tree computation.
  4. Use generate_chart on tree, feature importance, or validation result tables after run_analysis succeeds.
