Taiyi (太一): A Bilingual (Chinese and English) Fine-Tuned Large Language Model for Diverse Biomedical Tasks

Project Background

With the rapid development of deep learning technology, large language models (LLMs) like ChatGPT have made significant progress in the field of natural language processing. In the context of biomedical applications, large language models facilitate communication between healthcare professionals and patients, provide valuable medical information, and have enormous potential in assisting diagnosis, biomedical knowledge discovery, drug development, and personalized healthcare solutions, among others. However, in the AI community, there is a relative scarcity of existing open-source biomedical large models, with most of them primarily focused on monolingual medical question-answering dialogues in either Chinese or English. Therefore, this project embarks on research dedicated to large models for the biomedical domain and introduces the first version of a bilingual (Chinese and English) biomedical large language model named 'Taiyi', aiming to explore the capabilities of large models in handling a variety of bilingual natural language processing tasks in the biomedical field.

NEWs

• 2024/03/01 Our paper is online in JAMIA.
• 2024/01/05 We released our raw instruction data (Taiyi_Instruction_Data_001). The data is distributed under CC BY-NC-SA 4.0. The original benchmark datasets that support this study are available from the official websites of natural language processing challenges with Data Use Agreements.
• 2024/01/03 Due to limited resources, the demo was moved to huggingface space and used INT8 quantitative deployment. To experience better results, it is recommended to download weights and use scripts for non-quantitative deployment testing.

Project Highlights

• Rich Biomedical Training Resources：For the biomedical domain, this project has collected and organized a diverse set of bilingual (Chinese and English) Biomedical Natural Language Processing (BioNLP) training datasets. This collection includes a total of 38 Chinese datasets covering 10 BioNLP tasks and 102 English datasets covering 12 BioNLP tasks. To facilitate task-specific requirements, standardized data formats have been designed and applied for consistent formatting across all datasets.
• Promising Bilingual BioNLP Multi-Task Capability：Using rich bilingual instruction data (over 1 million samples) to fine-tune the LLM, the model show the bilingual capability in various BioNLP tasks including intelligent biomedical question-answering, biomedical dialogues, report generation, information extraction, machine translation, title generation, text classification, and more.
• Outstanding Generalization Capability Besides the biomedical conversation abilities, the model still retains general domain conversation abilities. Through the design of diverse instruction templates, it exhibits good generalization across various scenarios of similar tasks, and even stimulates the model's ability for zero-shot learning.

To promote the development of NLP in the biomedical field, this project releases Chinese-English BioNLP dataset curation details, Taiyi large model weights, and model inference usage scripts.

User Input：

Output a title for the following abstract:
The incidence of diabetes mellitus has been increasing, prompting the search for non-invasive diagnostic methods. Although current methods exist, these have certain limitations, such as low reliability and accuracy, difficulty in individual patient adjustment, and discomfort during use. This paper presents a novel approach for diagnosing diabetes using high-frequency ultrasound (HFU) and a convolutional neural network (CNN). This method is based on the observation that glucose in red blood cells (RBCs) forms glycated hemoglobin (HbA1c) and accumulates on its surface. The study incubated RBCs with different glucose concentrations, collected acoustic reflection signals from them using a custom-designed 90-MHz transducer, and analyzed the signals using a CNN. The CNN was applied to the frequency spectra and spectrograms of the signal to identify correlations between changes in RBC properties owing to glucose concentration and signal features. The results confirmed the efficacy of the CNN-based approach with a classification accuracy of 0.98. This non-invasive diagnostic technology using HFU and CNN holds promise for in vivo diagnosis without the need for blood collection.

For detailed information on the instructional data used for training, please refer to the "Instruction-Tuning Data Details".

Model Training

Introduction to the Base Model

The current version of Taiyi is based on the Qwen-7B-base model, which has been fine-tuned through Instruct-tuning. Qwen-7B is a 7 billion-parameter model in the Alibaba Cloud's Qwen large model series. It has been pre-trained on over 200 trillion tokens, encompassing high-quality data in Chinese, English, multiple languages, code, mathematics, and more. The training corpus covers both general and specialized domains.

Training Details

We conducted instruction-guided fine-tuning using Qlora on 6 Nvidia A40 48 GB GPUs. Our training code was modified based on project Firefly. The key hyperparameters used in the training process are as follows:

num_train_epochs:3
per_device_train_batch_size:12
gradient_accumulation_steps:2
learning_rate:0.0002
max_seq_length:1024
lr_scheduler_type:"constant_with_warmup"
warmup_ratio:0.1
lora_rank:64
lora_alpha:16
lora_dropout:0.05
weight_decay:0
max_grad_norm:0.3

Our training dataset consists of approximately 1 million training samples. Each epoch of training takes approximately two days to complete.

To install all dependencies automatically using the command:

$ pip install -r requirements.txt

Model Inference

We concatenate multi-turn dialogues into the following format, and then tokenize them. Where eod is the special character <|endoftext|> in the qwen tokenizer.

<eod>input1<eod>answer1<eod>input2<eod>answer2<eod>.....

The following code can be used to perform inference using our model:

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch

model_name = "DUTIR-BioNLP/Taiyi-LLM"

device = 'cuda:0'

model = AutoModelForCausalLM.from_pretrained(
    model_name,
    low_cpu_mem_usage=True,
    torch_dtype=torch.float16,
    trust_remote_code=True,
    device_map = device
)


model.eval()
tokenizer = AutoTokenizer.from_pretrained(
    model_name,
    trust_remote_code=True
)

import logging
logging.disable(logging.WARNING)
tokenizer.pad_token_id = tokenizer.eod_id
tokenizer.bos_token_id = tokenizer.eod_id
tokenizer.eos_token_id = tokenizer.eod_id
history_token_ids = torch.tensor([[]], dtype=torch.long)
max_new_tokens = 500
top_p = 0.9
temperature = 0.3
repetition_penalty = 1.0

# begin chat
history_max_len = 1000 
utterance_id = 0
history_token_ids = None

user_input = "Hi，could you please introduce yourself？"

input_ids = tokenizer(user_input, return_tensors="pt", add_special_tokens=False).input_ids
bos_token_id = torch.tensor([[tokenizer.bos_token_id]], dtype=torch.long)
eos_token_id = torch.tensor([[tokenizer.eos_token_id]], dtype=torch.long)
user_input_ids = torch.concat([bos_token_id,input_ids, eos_token_id], dim=1)


model_input_ids = user_input_ids.to(device)
with torch.no_grad():
    outputs = model.generate(
        input_ids=model_input_ids, max_new_tokens=max_new_tokens, do_sample=True, top_p=top_p,
        temperature=temperature, repetition_penalty=repetition_penalty, eos_token_id=tokenizer.eos_token_id
    )

response = tokenizer.batch_decode(outputs)
print(response[0])
#<|endoftext|>Hi，could you please introduce yourself？<|endoftext|>Hello! My name is Taiyi,.....<|endoftext|>

We provide two test codes for dialogue. You can use the code in dialogue_one_trun.py to test single-turn QA dialogue, or use the sample code in dialogue_multi_trun.py to test multi-turn conversational QA.

Note: To ensure fast inference speed, we recommend using a 4090 GPU.

Overall Performance

Limitation and Future Work

Limitations

The goal of this project is to explore the Chinese English bilingual natural language processing capabilities of the large model in the biomedical field. However, there are some shortcomings that must be considered in Taiyi model at present:

• Misunderstanding: Like all major language models, there is a risk of misunderstanding or misinterpretation, especially when dealing with specialized terminology or complex concepts in the biomedical field. In this case, our model may provide inaccurate answers or explanations.

• Hallucinations: Large language models sometimes generate meaningless or completely unrelated responses to a given input. This' hallucination 'may be particularly problematic when users are unfamiliar with the discussion topic, as they may not be able to easily identify errors in the model output.

• Limited information: Despite our commitment to becoming a comprehensive language model in the biomedical field, the knowledge of the model is still limited and may not cover all aspects of each field or profession. Users should be aware that the information in the model may not be comprehensive and use it with caution when in-depth or professional knowledge is needed.

• Bias: The training data of the model may contain biases, which may be reflected in the model's response. We strive to reduce bias, but we cannot completely eliminate it. Users should handle potential bias issues in model responses with caution.

• Limited long multi-turn conversational ability: Due to the current computational constraints of our team, the max token length we could set during training was 1024. Therefore, our current model is most competitive in relatively short conversations (around 5 turns).

• Limited topic switching ability: Due to current constraints on information and computational resources, our model may exhibit instability in multi-turn conversations covering multiple topics with large spans. Therefore, when conversing with Taiyi, users should try to maintain consistency in the dialogue topic.

Note: The Taiyi model is intended to provide information and knowledge, but should not be used as a substitute for medical professionals' advice or diagnosis. Any decision involving personal health should be consulted with professional medical personnel.

Future Work

• Open source data and technical manuscripts: Organize and improve data resources and model training technical manuscripts, and will be released as open source in the future.

• Continuing pretraining: Due to current computing resource limitations, the current version of Taiyi mainly performs instruction data fine-tuning and does not use massive biomedical resources to continue pretraining. In the future, this project will explore the use of large model bases in the biomedical field resources to futher pretraining.

• Reinforcement learning enhances performance: This project will explore how to further enhance the performance of models and align human intentions using reinforcement learning methods.

• Enhanced interpretability: Compared to the general field, the biomedical field requires higher interpretability of model prediction results. In the future, we will explore the interpretability methods of Taiyi on various BioNLP tasks.

• Enhanced security: Although security data has been added for training in this project, model security in the biomedical field is still insufficient. We will continue to explore how to use biomedical knowledge bases to enhance model security.
