GRU 预测
仅在样本量和序列长度足够时使用。确认窗口、特征和预测期,严格按时间划分训练验证,避免泄漏,报告基线对比、误差和不确定性;小数据优先建议传统时序模型。
Tool routing
- Use
get_schemato identify the time column, target column, feature columns, and source table. - Use
query_dataonly to verify sorted sequence length, missingness, and whether the sample size is sufficient. - Use
run_analysiswithanalysis_name="Time_Series_GRU"for the actual model computation. - Use
generate_charton forecast or validation result tables afterrun_analysissucceeds.
