# Chinese Sentence BERT |
|
|
|
## Model description |
|
|
|
This is the sentence embedding model pre-trained by [UER-py](https://github.com/dbiir/UER-py/), which is introduced in [this paper](https://arxiv.org/abs/1909.05658). |
|
|
|
## Training data |
|
|
|
[ChineseTextualInference](https://github.com/liuhuanyong/ChineseTextualInference/) is used as training data. |
|
|
|
## Training procedure |
|
|
|
The model is fine-tuned by [UER-py](https://github.com/dbiir/UER-py/) on [Tencent Cloud](https://cloud.tencent.com/). We fine-tune five epochs with a sequence length of 128 on the basis of the pre-trained model [chinese_roberta_L-12_H-768](https://huggingface.co/uer/chinese_roberta_L-12_H-768). At the end of each epoch, the model is saved when the best performance on development set is achieved. |
|
|
|
``` |
|
python3 finetune/run_classifier_siamese.py --pretrained_model_path models/cluecorpussmall_roberta_base_seq512_model.bin-250000 \ |
|
--vocab_path models/google_zh_vocab.txt \ |
|
--config_path models/sbert/base_config.json \ |
|
--train_path datasets/ChineseTextualInference/train.tsv \ |
|
--dev_path datasets/ChineseTextualInference/dev.tsv \ |
|
--learning_rate 5e-5 --epochs_num 5 --batch_size 64 |
|
``` |
|
|
|
Finally, we convert the pre-trained model into Huggingface's format: |
|
|
|
``` |
|
python3 scripts/convert_sbert_from_uer_to_huggingface.py --input_model_path models/finetuned_model.bin \ |
|
--output_model_path pytorch_model.bin \ |
|
--layers_num 12 |
|
``` |
