SEA-LION-BERT
SEA-LION stands for Southeast Asian Languages In One Network.
This is the card for the SEA-LION-BERT base model.
How To Use
from transformers import AutoModelForMaskedLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained('aisingapore/sealion-bert-base', trust_remote_code=True)
model = AutoModelForMaskedLM.from_pretrained('aisingapore/sealion-bert-base', trust_remote_code=True)
# prepare input
text = "Give me a <|mask|>!!!"
encoded_input = tokenizer(text, return_tensors='pt')
Model Details
Model Description
The SEA-LION-BERT model is built on the MosaicBERT architecture and has a vocabulary size of 256K.
For tokenization, the model employs our custom SEABPETokenizer, which is specially tailored for SEA languages, ensuring optimal model performance.
The training data for SEA-LION-BERT encompasses 790B tokens.
