RoCBert

RoCBert is a pretrained Chinese BERT model designed against adversarial attacks like typos and synonyms. It is pretrained with a contrastive learning objective to align normal and adversarial text examples. The examples include different semantic, phonetic, and visual features of Chinese. This makes RoCBert more robust against manipulation.

You can find all the original RoCBert checkpoints under the weiweishi profile.

Click on the RoCBert models in the right sidebar for more examples of how to apply RoCBert to different Chinese language tasks.

The example below demonstrates how to predict the [MASK] token with [Pipeline], [AutoModel], and from the command line.

import torch
from transformers import pipeline

pipeline = pipeline(
   task="fill-mask",
   model="weiweishi/roc-bert-base-zh",
   dtype=torch.float16,
   device=0
)
pipeline("這家餐廳的拉麵是我[MASK]過的最好的拉麵之")

import torch
from transformers import AutoModelForMaskedLM, AutoTokenizer

tokenizer = AutoTokenizer.from_pretrained(
   "weiweishi/roc-bert-base-zh",
)
model = AutoModelForMaskedLM.from_pretrained(
   "weiweishi/roc-bert-base-zh",
   dtype=torch.float16,
   device_map="auto",
)
inputs = tokenizer("這家餐廳的拉麵是我[MASK]過的最好的拉麵之", return_tensors="pt").to(model.device)

with torch.no_grad():
   outputs = model(**inputs)
   predictions = outputs.logits

masked_index = torch.where(inputs['input_ids'] == tokenizer.mask_token_id)[1]
predicted_token_id = predictions[0, masked_index].argmax(dim=-1)
predicted_token = tokenizer.decode(predicted_token_id)

print(f"The predicted token is: {predicted_token}")

echo -e "這家餐廳的拉麵是我[MASK]過的最好的拉麵之" | transformers run --task fill-mask --model weiweishi/roc-bert-base-zh --device 0
