chinese macbert base

Introduction

MacBERT is an enhanced version of BERT specifically designed for Chinese natural language processing. It introduces a new pre-training task called MLM as correction, which reduces the gap between pre-training and fine-tuning by replacing masked tokens with similar words instead of using the [MASK] token. This approach utilizes the Synonyms toolkit to find similar words based on word2vec similarity calculations. The model also incorporates techniques such as Whole Word Masking (WWM), N-gram masking, and Sentence-Order Prediction (SOP), and is directly compatible with the original BERT architecture.

Architecture

MacBERT maintains the same neural architecture as the original BERT, ensuring compatibility. The enhancements focus on pre-training tasks, employing strategies like using similar words for masking instead of the [MASK] token, adopting whole word and N-gram masking, and implementing sentence-order prediction.

Training

The training process of MacBERT involves a pre-training stage where the model is exposed to a masked language model (MLM) as a correction task. This involves using similar words for masking and integrating additional techniques such as whole word and N-gram masking, along with sentence-order prediction, to improve the model's performance on Chinese NLP tasks.
