Description: An ensemble of both discriminated and generated models. The former is a multimodal method which utilizes text, layout and image, and we train this model with two different sequence lengths, 2048 and 512 respectively. The texts and boxes are generated by independent OCR models. The latter model is an end-to-end method which directly generates K-V pairs for an input image.
