Release

***** New February, 2020: UniLM v2 | MiniLM v1 | LayoutLM v1 | s2s-ft v1 release *****

• LayoutLM 1.0 (February 18, 2020): pre-trained models for document (image) understanding (e.g. receipts, forms, etc.) . It achieves new SOTA results in several downstream tasks, including form understanding (the FUNSD dataset from 70.72 to 79.27), receipt understanding (the ICDAR 2019 SROIE leaderboard from 94.02 to 95.24) and document image classification (the RVL-CDIP dataset from 93.07 to 94.42).

• s2s-ft 1.0 (February 26, 2020): A PyTorch package used to fine-tune pre-trained Transformers for sequence-to-sequence language generation. "s2s-ft: Fine-Tuning Pre-Trained Transformers for Sequence-to-Sequence Learning"
• MiniLM 1.0 (February 26, 2020): deep self-attention distillation is all you need (for task-agnostic knowledge distillation of pre-trained Transformers). MiniLM (12-layer, 384-hidden) achieves 2.7x speedup and comparable results over BERT-base (12-layer, 768-hidden) on NLU tasks as well as strong results on NLG tasks. The even smaller MiniLM (6-layer, 384-hidden) obtains 5.3x speedup and produces very competitive results. "MiniLM: Deep Self-Attention Distillation for Task-Agnostic Compression of Pre-Trained Transformers"
• UniLM 2.0 (February 28, 2020): unified pre-training of bi-directional LM (via autoencoding) and sequence-to-sequence LM (via partially autoregressive) w/ Pseudo-Masked Language Model for language understanding and generation. UniLM v2 achieves new SOTA in a wide range of natural language understanding and generation tasks. "UniLMv2: Pseudo-Masked Language Models for Unified Language Model Pre-Training ICML 2020"

***** October 1st, 2019: UniLM v1 release *****

• UniLM v1 (September 30, 2019): the code and pre-trained models for the NeurIPS 2019 paper entitled "Unified Language Model Pre-training for Natural Language Understanding and Generation". UniLM (v1) achieves the new SOTA results in NLG (especially sequence-to-sequence generation) tasks, including abstractive summarization (the Gigaword and CNN/DM datasets), question generation (the SQuAD QG dataset), etc.
