What is UniLM?
UniLM stands for Unified pre-trained Language Model. It is a state-of-the-art pre-training model in Natural Language Understanding and Natural Language Generation. Being the new benchmark in the field of natural language processing, UniLM leverages a shared Transformer network jointly pre-trained on unidirectional, bidirectional, and sequence-to-sequence language modeling. The model uses special self-attention masks to predict the context so that it could hold top places in a variety of NLP benchmarks.
Contributing to the development history of UniLM, it has open-sourced its models and code for further research improvements. Establishing new state-of-the-art records on a number of tasks, it has outperformed well-renowned models such as BERT on benchmarks like GLUE, SQuAD 2.0, and CoQA.
Key Features & Benefits of UniLM

How UniLM Works
UniLM works on the shared pre-training of the Transformer network for different language modeling tasks. Further to that, we provide in this section a technical overview of its innate technology: it sets up a general framework of the Transformer network, which proves very effective in various applications of NLP due to its high parallelization capability, hence bettering performance; self-attention masks with special masks control prediction contexts so as to turn on unidirectional, bidirectional, and sequence-to-sequence manners.
Pre-training Tasks: It performs pre-training with tasks involving understanding and generating text for a wide understanding of the nuances of language.
It is pre-trained on huge datasets and then fine-tuned for specific applications. This procedure makes UniLM very effective in a wide range of applications of NLP with high performance.
Pros and Cons of UniLM
Like any other tool, UniLM also has some advantages and its sets of disadvantages associated:
