Release

***** New September, 2021: TrOCR release *****

• TrOCR (September 22, 2021): Transformer-based OCR with pre-trained models, which leverages the Transformer architecture for both image understanding and bpe-level text generation. The TrOCR model is simple but effective (convolution free), and can be pre-trained with large-scale synthetic data and fine-tuned with human-labeled datasets. "TrOCR: Transformer-based Optical Character Recognition with Pre-trained Models"

***** August, 2021: LayoutReader release *****

• LayoutReader (August 26, 2021): pre-training of text and layout for reading order detection. The pre-trained LayoutReader significantly improves both open-source and commercial OCR engines in ordering text lines. Meanwhile, we also created a reading order benchmark dataset ReadingBank to further empower the research in this area. "LayoutReader: Pre-training of Text and Layout for Reading Order Detection EMNLP 2021"

***** August, 2021: DeltaLM release *****

• DeltaLM (August, 2021): encoder-decoder pre-training for language generation and translation. DeltaLM ranks first on the WMT21 multilingual translation task. The task requires a model to translate between 102 languages. "DeltaLM: Encoder-Decoder Pre-training for Language Generation and Translation by Augmenting Pretrained Multilingual Encoders."

***** July, 2021: BEiT release *****

• BEiT (June 15, 2021): BERT Pre-Training of Image Transformers. BEiT-large achieves state-of-the-art results on ADE20K (a big jump to 57.0 mIoU) for semantic segmentation. BEiT-large achieves state-of-the-art ImageNet top-1 accuracy (88.6%) under the setting without extra data other than ImageNet-22k. "BEiT: BERT Pre-Training of Image Transformers"

***** June, 2021: LayoutXLM | AdaLM | MiniLMv2 release *****
