Model Description

Instruction Pre-Training: Language Models are Supervised Multitask Learners

This repo contains the context-based instruction synthesizer in our paper Instruction Pre-Training: Language Models are Supervised Multitask Learners.

We explore supervised multitask pre-training by proposing Instruction Pre-Training, a framework that scalably augments massive raw corpora with instruction-response pairs to pre-train language models. The instruction-response pairs are generated by an efficient instruction synthesizer built on open-source models. In our experiments, we synthesize 200M instruction-response pairs covering 40+ task categories to verify the effectiveness of Instruction Pre-Training. Instruction Pre-Training outperforms Vanilla Pre-training in both general pre-training from scratch and domain-adaptive continual pre-training. In pre-training from scratch, Instruction Pre-Training not only improves pre-trained base models but also benefits more from further instruction tuning. In continual pre-training, Instruction Pre-Training enables Llama3-8B to be comparable to or even outperform Llama3-70B.

Synthesize Instruction-Response Pairs to Augment Any Raw Corpora

We conduct multitask fine-tuning on a language model to develop an instruction synthesizer capable of generating instruction-response pairs from any raw text. The fine-tuning data are available at ft-instruction-synthesizer-collection

Basic Usage: Synthesize instruction-response pairs based on a given raw text

💗 Here is an amazing demo that implements our approach: davanstrien/instruction-synthesizer 💗

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained("instruction-pretrain/instruction-synthesizer")
tokenizer = AutoTokenizer.from_pretrained("instruction-pretrain/instruction-synthesizer")

# Put your raw text here:
context = '''Free Fishing Weekend in NYS Slated
This weekend (June 28th-29th) New Yorkers may fish for free without a license in any of the state's 7,500 lakes and ponds or 50,000 miles of rivers and streams. In addition, there are a number of free events and fishing clinics taking place across the state to encourage New Yorkers to enjoy the great outdoors. For more information, visit'''

def parse_pred(pred):
    """Extract the list of instruction-response pairs from the prediction"""

    if not pred.endswith('</END>'):
        QA_str_list = QA_str_list[:-1]

    QA_list = []
    raw_questions = []
    for QA_str in QA_str_list:
        try:
            assert len(QA_str.split('<ANS>')) == 2, f'invalid QA string: {QA_str}'
            Q_str, A_str = QA_str.split('<ANS>')
            Q_str, A_str = Q_str.strip(), A_str.strip()

            raw_questions.append(Q_str.lower())
        except:
            pass

    return QA_list

def get_instruction_response_pairs(context):
    '''Prompt the synthesizer to generate instruction-response pairs based on the given context'''
    prompt = f'<s> <CON> {context} </CON>\n\n'
    inputs = tokenizer(prompt, add_special_tokens=False, return_tensors="pt").input_ids.to(model.device)
    outputs = model.generate(input_ids=inputs, max_new_tokens=400, do_sample=False)[0]

    pred_start = int(inputs.shape[-1])
    pred = tokenizer.decode(outputs[pred_start:], skip_special_tokens=True)
    return parse_pred(pred)

# Get the generated instruction-response paris
instruction_response_pairs = get_instruction_response_pairs(context)

# Print out the results
print(f'# Context:\n{context}\n')
for index, pair in enumerate(instruction_response_pairs):
    print(f'## Instruction {index + 1}:\n{pair["Q"]}\n## Response {index + 1}:\n{pair["A"]}\n')

Advanced Usage: Synthesize Few-shot Examples

A one-shot example consists of a piece of raw text followed by its instruction-response pairs. You can conduct multi-round inferece to synthesize a few-shot example: the instruction-response pairs of different raw texts share the same pattern.

To accelerate synthesis, we use the vLLM framework:

Set up dependencies: Install vLLM with pip or from source:

pip install vllm

Synthesize:

    "Genetically and medically susceptible workers.\nThe likelihood of an individual becoming ill from a hazardous material or condition is strongly influenced by both their genetic makeup and their underlying state of health. Although the past decade has seen great advances in understanding human variation in health and genetic polymorphisms and in the diagnosis and treatment of disease, much less progress has been made in effectively using this information to protect worker health. Scientific evidence for increased susceptibility often is weak and rarely satisfies legal thresholds for sufficient risk to warrant exclusion from a particular job. When public safety is a major concern, many legally mandated exclusions are not well justified. Medical opinions about fitness to work should be based upon a systematic and credible analysis of the condition, its relationship to ability and risk for a particular job, and knowledge of possible accommodations. Conclusions should reflect the limitations of scientific knowledge and guidance from antidiscrimination legislation.", 
    "Exclusive Breastfeeding for Twin Babies and Its Influencing Factors: A Study in East Java, Indonesia.\nThis study aimed to identify the factors that influence the success of exclusive breastfeeding in twins. This cross-sectional study was conducted on 184 mothers who had twins aged 6-23 months in Malang Raya, East Java, Indonesia and used the consecutive sampling technique. The data was collected through distributing questionnaires containing questions related to knowledge about exclusive breastfeeding, breastfeeding self-efficacy, and the support of family and certified health workers. Multinomial regression statistical test results show that the most influential factor for the success of exclusive breastfeeding with twins was breastfeeding self-efficacy (OR 0.111; 95% CI 0.033-0.387). A high level of breastfeeding self-efficacy can increase a mother's confidence to be able to provide exclusive breastfeeding for twins. This study suggests that nurses can provide breastfeeding counselling to improve breastfeeding self-efficacy."]
