# Herbert: Pretrained Bert Model for Herbal Medicine

**Herbert** is a pretrained model for herbal medicine research, developed based on the `bert-base-chinese` model. The model has been fine-tuned on domain-specific data from 675 ancient books and 32 Traditional Chinese Medicine (TCM) textbooks. It is designed to support a variety of TCM-related NLP tasks.

---

## Introduction

This model is optimized for TCM-related tasks, including but not limited to:
- Herbal formula encoding
- Domain-specific word embedding
- Classification, labeling, and sequence prediction tasks in TCM research

Herbert combines the strengths of modern pretraining techniques and domain knowledge, allowing it to excel in TCM-related text processing tasks.

### requirements
"transformers_version": "4.45.1"

###  Quickstart

#### Use Huggingface
```python
from transformers import AutoTokenizer, AutoModel

# Replace "Chengfengke/herbert" with the Hugging Face model repository name
model_name = "Chengfengke/herbert"

# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModel.from_pretrained(model_name)

# Input text
text = "中医理论是我国传统文化的瑰宝。"

# Tokenize and prepare input
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding="max_length", max_length=128)

# Get the model's outputs
with torch.no_grad():
    outputs = model(**inputs)

# Get the embedding (sentence-level average pooling)
sentence_embedding = outputs.last_hidden_state.mean(dim=1)

print("Embedding shape:", sentence_embedding.shape)
print("Embedding vector:", sentence_embedding)
```


#### LocalModel
```python
from transformers import BertTokenizer, BertForMaskedLM

# Load the model and tokenizer
model_name = "Chengfengke/herbert"
tokenizer = BertTokenizer.from_pretrained(model_name)
model = BertForMaskedLM.from_pretrained(model_name)
inputs = tokenizer("This is an example text for herbal medicine.", return_tensors="pt")
outputs = model(**inputs)
```
