What is tapex-large-finetuned-wtq?
TAPEX (Table Pre-training via Execution) is an advanced language model specifically designed for table reasoning tasks. This large variant, containing 406M parameters, has been fine-tuned on the WikiTableQuestions dataset to excel at complex table question answering. The model leverages a neural SQL executor approach, combining the capabilities of BART's encoder-decoder architecture with sophisticated table understanding.
Implementation Details
Built on the BART architecture, TAPEX utilizes a bidirectional encoder similar to BERT and an autoregressive decoder reminiscent of GPT. The model learns table reasoning by synthesizing and executing SQL queries during pre-training, making it particularly effective at understanding tabular data structures.
