Training Details

Training Method

We used LoRA to speed up the training process, targeting the q_proj, k_proj, v_proj, and o_proj modules.

Uses

To accelerate the inference, we strongly recommend running Jellyfish using vLLM.

Python Script

We provide two simple Python code examples for inference using the Jellyfish model.

Using Transformers and Torch Modules

python

from transformers import AutoModelForCausalLM, AutoTokenizer, GenerationConfig
import torch

if torch.cuda.is_available():
    device = "cuda"
else:
    device = "cpu"

# Model will be automatically downloaded from HuggingFace model hub if not cached.
# Model files will be cached in "~/.cache/huggingface/hub/models--NECOUDBFM--Jellyfish/" by default.
# You can also download the model manually and replace the model name with the path to the model files.
model = AutoModelForCausalLM.from_pretrained(
    "NECOUDBFM/Jellyfish",
    torch_dtype=torch.float16,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("NECOUDBFM/Jellyfish")

system_message = "You are an AI assistant that follows instruction extremely well. Help as much as you can."

# You need to define the user_message variable based on the task and the data you want to test on.
user_message = "Hello, world."

prompt = f"<|start_header_id|>system<|end_header_id|>{system message}<|eot_id|>\n<|start_header_id|>user<|end_header_id|>{user_message}<|eot_id|>\n<|start_header_id|>assistant<|end_header_id|>"
inputs = tokenizer(prompt, return_tensors="pt")
input_ids = inputs["input_ids"].to(device)

# You can modify the sampling parameters according to your needs.
generation_config = GenerationConfig(
    do_samples=True,
    temperature=0.35,
    top_p=0.9,
)

with torch.no_grad():
    generation_output = model.generate(
        input_ids=input_ids,
        generation_config=generation_config,
        return_dict_in_generate=True,
        output_scores=True,
        max_new_tokens=1024,
        pad_token_id=tokenizer.eos_token_id,
        repetition_penalty=1.15,
    )

output = generation_output[0]
response = tokenizer.decode(
    output[:, input_ids.shape[-1] :][0], skip_special_tokens=True
).strip()

print(response)

Using vLLM

python

from vllm import LLM, SamplingParams

# To use vllm for inference, you need to download the model files either using HuggingFace model hub or manually.
# You should modify the path to the model according to your local environment.
path_to_model = (
    "/workspace/models/Jellyfish"
)

model = LLM(model=path_to_model)

# You can modify the sampling parameters according to your needs.
# Caution: The stop parameter should not be changed.
sampling_params = SamplingParams(
    temperature=0.35,
    top_p=0.9,
    max_tokens=1024,
    stop=["<|eot_id|>"],
)

system_message = "You are an AI assistant that follows instruction extremely well. Help as much as you can."

# You need to define the user_message variable based on the task and the data you want to test on.
user_message = "Hello, world."

prompt = ff"<|start_header_id|>system<|end_header_id|>{system message}<|eot_id|>\n<|start_header_id|>user<|end_header_id|>{user_message}<|eot_id|>\n<|start_header_id|>assistant<|end_header_id|>"
outputs = model.generate(prompt, sampling_params)
response = outputs[0].outputs[0].text.strip()
print(response)

Prompts

We provide the prompts used for both fine-tuning and inference. You can structure your data according to these prompts.

System Message

You are an AI assistant that follows instruction extremely well.
User will give you a question. Your task is to answer as faithfully as you can.

For Error Detection

There are two forms of the error detection task. In the first form, a complete record row is provided, and the task is to determine if a specific value is erroneous. In the second form, only the value of a specific attribute is given, and the decision about its correctness is based solely on the attribute's name and value. The subsequent prompt examples pertain to these two forms, respectively.

Your task is to determine if there is an error in the value of a specific attribute within the whole record provided.
The attributes may include {attribute 1}, {attribute 2}, ...
Errors may include, but are not limited to, spelling errors, inconsistencies, or values that don't make sense given the context of the whole record.
Record [{attribute 1}: {attribute 1 value}, {attribute 2}: {attribute 2 value}, ...]
Attribute for Verification: [{attribute X}: {attribute X value}]
Question: Is there an error in the value of {attribute X}? Choose your answer from: [Yes, No].

Your task is to determine if there is an error in the value of a specific attribute.
The attributes may belong to a {keyword} record and could be one of the following: {attribute 1}, {attribute 2}, ...
Errors can include, but are not limited to, spelling errors, inconsistencies, or values that don't make sense for that attribute.  
Note: Missing values (N/A or \"nan\") are not considered errors.
Attribute for Verification: [{attribute X}: {attribute X value}]
Question: Is there an error in the value of {attribute X}? Choose your answer from: [Yes, No].

For Data Imputation

You are presented with a {keyword} record that is missing a specific attribute: {attribute X}.
Your task is to deduce or infer the value of {attribute X} using the available information in the record.  
You may be provided with fields like {attribute 1}, {attribute 2}, ... to help you in the inference.  
Record: [{attribute 1}: {attribute 1 value}, {attribute 2}: {attribute 2 value}, ...]  
Based on the provided record, what would you infer is the value for the missing attribute {attribute X}?  
Answer only the value of {attribute X}.

For Schema Matching

Your task is to determine if the two attributes (columns) are semantically equivalent in the context of merging two tables.
Each attribute will be provided by its name and a brief description.
Your goal is to assess if they refer to the same information based on these names and descriptions provided.
Attribute A is [name: {value of name}, description: {value of description}].
Attribute B is [name: {value of name}, description: {value of description}].
Are Attribute A and Attribute B semantically equivalent? Choose your answer from: [Yes, No].

For Entity Matching

You are tasked with determining whether two records listed below are the same based on the information provided.  
Carefully compare the {attribute 1}, {attribute 2}... for each record before making your decision.  
Note that missing values (N/A or \"nan\") should not be used as a basis for your decision.
Record A: [{attribute 1}: {attribute 1 value}, {attribute 2}: {attribute 2 value}, ...]  
Record B: [{attribute 1}: {attribute 1 value}, {attribute 2}: {attribute 2 value}, ...]  
Are record A and record B the same entity? Choose your answer from: [Yes, No].

For Column Type Annotation

We follow the prompt in Column Type Annotation using ChatGPT (text+inst+2-step).

For Attribute Value Extraction

We follow the prompt in Product Attribute Value Extraction using Large Language Models (textual, w/o examples).
