Prediction settings: Text metric learning

To score (predict) new data using a built model through the H2O Hydrogen Torch UI, H2O Hydrogen Torch requires the specification of certain settings refer as prediction settings (which are comprised of a certain dataset, prediction and environment settings similar to those when creating an experiment). Below observe the prediction settings for a text metric learning model.

General settings​

Experiment​

Defines the model (experiment) H2O Hydrogen Torch uses to score new data.

Prediction name​

It defines the name of the prediction.

Dataset settings​

Dataset​

Specifies the dataset to use for scoring.

Test dataframe​

Defines the file(s) containing the test dataframe that H2O Hydrogen Torch will use for scoring.

note
  • Image regression | Image classification | Image metric learning | Text regression | Text classification | Text sequence to sequence | Text span prediction | Text token classification | Text metric learning | Audio regression | Audio classification
    • Defines a .csv or .pq file containing the test dataframe that H2O Hydrogen Torch will use for scoring.
      note

      The test dataframe should have the same format as the train dataframe but does not require label columns.

  • Image object detection | Image semantic segmentation | Image instance segmentation
    • Defines a .pq file containing the test dataframe that H2O Hydrogen Torch will use for scoring.

Text column​

Defines the column name with the input text that H2O Hydrogen Torch will use during scoring.

Prediction settings​

Metric​

Specifies the evaluation metric to use to evaluate the model's accuracy.

note

Usually, the evaluation metric should reflect the quantitative way of assessing the model's value for the corresponding use case.

Top K similar​

Defines the number (k) of similar predictions to keep for each record during the model training.

note

Defining this setting impacts output predictions and metrics (metrics that rely on some top-k selection) but not the training process.

Environment settings​

GPUs​

Specifies the list of GPUs H2O Hydrogen Torch can use for scoring. GPUs are listed by name, referring to their system ID (starting from 1).
