## Hetero Poisson Regression Configuration Usage Guide.

#### Example Tasks

This section introduces the dsl and conf for different types of tasks.

1. Train Task:

    dsl: test_hetero_poisson_train_job_dsl.json

    runtime_config : test_hetero_poisson_train_job_conf.json
    (with exposure variable column name specified)

2. Predict Task:

    dsl: test_hetero_poisson_predict_job_dsl.json

    runtime_config : test_hetero_predict_job_conf.json

3. Warm Start Task:

    dsl: test_hetero_poisson_warm_start_job_dsl.json

    runtime_config : test_hetero_warm_start_job_conf.json
      
4.  Validate Task (with early-stopping parameter specified):

    dsl: test_hetero_poisson_validate_job_dsl.json

    runtime_config : test_hetero_poisson_validate_job_conf.json
  
5. Train Task with Sparse Data:
    
    dsl: test_hetero_poisson_train_sparse_job_dsl.json

    runtime_config : test_hetero_poisson_train_sparse_job_conf.json
    (with exposure variable column name specified)

6. Cross Validation Task:

    dsl: test_hetero_poisson_cv_job_dsl.json

    runtime_config: test_hetero_poisson_cv_job_conf.json

Users can use following commands to run a task.

    flow job submit -c ${runtime_config} -d ${dsl}

After having finished a successful training task, you can use the obtained model to perform prediction. You need to add the corresponding model id and model version to the configuration [file](./test_hetero_poisson_predict_job_conf.json).
