class TapasForQuestionAnswering extends BertForQuestionAnswering

TapasForQuestionAnswering is an implementation of TaPas - a BERT-based model specifically designed for answering questions about tabular data. It takes TABLE and DOCUMENT annotations as input and tries to answer the questions in the document by using the data from the table. The model is based in BertForQuestionAnswering and shares all its parameters with it.

Pretrained models can be loaded with pretrained of the companion object:

val tapas = TapasForQuestionAnswering.pretrained()
  .setInputCols(Array("document_question", "table"))
  .setOutputCol("answer")

The default model is "table_qa_tapas_base_finetuned_wtq", if no name is provided.

For available pretrained models please see the Models Hub.
