有什么方法可以使用curl命令训练时间序列Google AutoML Tables模型吗？

问题描述

下面提供的JSON文件是request.json，用于使用Google AutoML表训练分类或回归模型。

{
  "datasetId": "dataset-id","displayName": "model-display-name","tablesModelMetadata": {
    "trainBudgetMilliNodeHours": "train-budget-milli-node-hours","optimizationObjective": "optimization-objective","targetColumnSpec": {
      "name": "projects/project-id/locations/location/datasets/dataset-id/tableSpecs/table-id/columnSpecs/target-column-id"
    }
  },}

我需要通过在json文件中提供“时间序列标识符”列和“预测地平线”来使用curl命令训练时间序列模型。所以我理想的请求文件应该是

{
  "datasetId": "dataset-id","forecastHorizon": "horizon","timeseriesIdentifier":"column-id",}

这样我就可以使用命令传递上面给出的request.json文件

curl -X POST \
-H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
https://endpoint/v1beta1/projects/project-id/locations/location/models/

有什么办法吗？

解决方法

目前，Cloud Auto ML Tables提供了predictions来解决回归或分类问题。

您应该考虑使用BigQuery ML为time series models创建模型语句，可以使用REST API在curl命令中传递参数“ timeSeriesIdColumn”和“ horizo​​n”。
