Prediction tabs

A prediction contains the following tabs that you can view when the prediction is running or completed:

Note

To learn how to view a running or completed prediction, see View running or completed prediction.

Each tab below, in turn, is explained.

Summary

On the Summary tab, H2O Hydrogen Torch displays the following table containing summary metrics about the selected prediction:

Name Description
Name Name of the prediction.
Dataset Dataset used for the experiment.
Problem Type Problem type of the experiment.
Fold The validation fold value.
Seed The random seed value that you selected for model training.
GPU List List of GPUs that H2O Hydrogen Torch used during model training.
Loss Loss refers to the objective function optimized directly during model training.
Metric Metric refers to the selected metric to evaluate model performance.
Epoch The number of epochs used to train the model.
Train Metric Train metric refers to evaluation metric computed on train data. A value for Train metric is available when Calculate Train Metric is turned on when defining the experiment settings.
Val Metric Val Metric refers to the evaluation metric computed on the validation data.
Test Metric Test metric refers to the evaluation metric computed on the test data.

Metrics

On the Metrics tab, H2O Hydrogen Torch displays all available test metrics applicable to the problem type of the prediction, if test dataset contains labels.

Test Prediction Insights

On the Test Prediction Insights tab, H2O Hydrogen Torch visualizes test samples and their prediction. In addition, if test dataset contains labels, visualizations are divided as follows:

  • Random test samples

    In the Random test samples tab, H2O Hydrogen Torch visualizes best and worst test samples and their prediction.

    Note

    Each random test sample contains a Loss value.

  • Best test samples

    In the Best test samples tab, H2O Hydrogen Torch visualizes the best test samples and their prediction. Samples in this tab can also be regarded as the model's smallest significant errors.

    Note

    Each best test sample contains a Loss value.

  • Worst test samples

    In the Worst test samples tab, H2O Hydrogen Torch visualizes the worst test samples and their prediction. Samples in this tab can also be regarded as the model's most significant errors. Samples in this tab can help identify issues the model might have.

    Note

    Each worst test sample contains a Loss value.

Note

Evaluating the best and the worst performance differs for each problem type and might vary from the selected loss and the selected metric to assess the model.

Logs

On the Logs tab, you can view and download the logs for the prediction in view.

To download the logs of a prediction:

  1. In the H2O Hydrogen Torch navigation menu, click View predictions.
  2. Click the name of the prediction you want to download its logs.
  3. Click Download logs/config.

Config

On the Config tab, you can view the configurations used for the experiment.
