BERT Predictor

Applies a BERT Classification model to the input table.

Options

Sentence column: A column with a plain text (String) or Documents, that contains text to be classified. No special pre-processing is needed.
Batch size: The number of rows to feed to the model simultaniously. During prediction it is typically possible to use a larger batch size than during model training.
Change prediction column name: If active a column with provided name will be created in the output table. Otherwise the default name will be used for the column with predictions.
Append individual class probabilities: If active the columns with class probabilities will be created in the output table.
Suffix for probability columns: If not empty the suffix will be added to every column name for class probabilities columns.

Use custom threshold for assigning the classes: If active it is possible to change the probability threshold for assigning the class. By default class is assigned by the biggest probability value.
Probability threshold: The class is assigned if the class probability is equal or higher then the value. Several classes might be assigned.
Fixed number of classes per prediction: If active it is possible to set up the desired number of classes for a prediction.
Number of classes per prediction: The fixed number of classes that will be assigned to the prediction.
Use custom class separator: If active it is possible to enter the separation character for the prediction. Prediction is represented as a string with separated values.
Class separator: A character that separates multiple labels for prediction.
