bert-base-cantonese

This model is a continuation of indiejoseph/bert-base-cantonese , a BERT-based model pre-trained on a substantial corpus of Cantonese text. The dataset was sourced from a variety of platforms, including news articles, social media posts, and web pages. The text was segmented into sentences containing 11 to 460 tokens per line. To ensure data quality, Minhash LSH was employed to eliminate near-duplicate sentences, resulting in a final dataset comprising 161,338,273 tokens. Training was conducted using the run_mlm.py script from the transformers library.
