Let’s begin by understanding the essential strategy of artificial knowledge era utilizing LLMs:
from transformers import AutoTokenizer, AutoModelForCausalLM # Load a pre-trained LLM model_name = "gpt2-large" tokenizer = AutoTokenizer.from_pretrained(model_name) mannequin = AutoModelForCausalLM.from_pretrained(model_name) # Outline a immediate for artificial knowledge era immediate = "Generate a buyer assessment for a smartphone:" # Generate artificial knowledge input_ids = tokenizer.encode(immediate, return_tensors="pt") output = mannequin.generate(input_ids, max_length=100, num_return_sequences=1) # Decode and print the generated textual content synthetic_review = tokenizer.decode(output[0], skip_special_tokens=True) print(synthetic_review)
This easy instance demonstrates how an LLM can be utilized to generate artificial buyer opinions. Nevertheless, the actual energy of LLM-driven artificial knowledge era lies in additional refined strategies and purposes.
2. Superior Strategies for Artificial Knowledge Technology
2.1 Immediate Engineering
Immediate engineering is essential for guiding LLMs to generate high-quality, related artificial knowledge. By fastidiously crafting prompts, we are able to management varied features of the generated knowledge, resembling model, content material, and format.
Instance of a extra refined immediate:
immediate = """
Generate an in depth buyer assessment for a smartphone with the next traits:
- Model: {model}
- Mannequin: {mannequin}
- Key options: {options}
- Ranking: {ranking}/5 stars
The assessment needs to be between 50-100 phrases and embrace each optimistic and adverse features.
Assessment:
"""
manufacturers = ["Apple", "Samsung", "Google", "OnePlus"]
fashions = ["iPhone 13 Pro", "Galaxy S21", "Pixel 6", "9 Pro"]
options = ["5G, OLED display, Triple camera", "120Hz refresh rate, 8K video", "AI-powered camera, 5G", "Fast charging, 120Hz display"]
rankings = [4, 3, 5, 4]
# Generate a number of opinions
for model, mannequin, characteristic, ranking in zip(manufacturers, fashions, options, rankings):
filled_prompt = immediate.format(model=model, mannequin=mannequin, options=characteristic, ranking=ranking)
input_ids = tokenizer.encode(filled_prompt, return_tensors="pt")
output = mannequin.generate(input_ids, max_length=200, num_return_sequences=1)
synthetic_review = tokenizer.decode(output[0], skip_special_tokens=True)
print(f"Assessment for {model} {mannequin}:n{synthetic_review}n")
This strategy permits for extra managed and various artificial knowledge era, tailor-made to particular situations or product varieties.
2.2 Few-Shot Studying
Few-shot studying entails offering the LLM with a couple of examples of the specified output format and elegance. This method can considerably enhance the standard and consistency of generated knowledge.
few_shot_prompt = """ Generate a buyer assist dialog between an agent (A) and a buyer (C) a few product concern. Comply with this format: C: Hey, I am having bother with my new headphones. The proper earbud is not working. A: I am sorry to listen to that. Are you able to inform me which mannequin of headphones you could have? C: It is the SoundMax Professional 3000. A: Thanks. Have you ever tried resetting the headphones by putting them within the charging case for 10 seconds? C: Sure, I attempted that, however it did not assist. A: I see. Let's strive a firmware replace. Are you able to please go to our web site and obtain the most recent firmware? Now generate a brand new dialog a few totally different product concern: C: Hello, I simply obtained my new smartwatch, however it will not activate. """ # Generate the dialog input_ids = tokenizer.encode(few_shot_prompt, return_tensors="pt") output = mannequin.generate(input_ids, max_length=500, num_return_sequences=1) synthetic_conversation = tokenizer.decode(output[0], skip_special_tokens=True) print(synthetic_conversation)
This strategy helps the LLM perceive the specified dialog construction and elegance, leading to extra practical artificial buyer assist interactions.
2.3 Conditional Technology
Conditional era permits us to regulate particular attributes of the generated knowledge. That is significantly helpful when we have to create various datasets with sure managed traits.
from transformers import GPT2LMHeadModel, GPT2Tokenizer
import torch
mannequin = GPT2LMHeadModel.from_pretrained("gpt2-medium")
tokenizer = GPT2Tokenizer.from_pretrained("gpt2-medium")
def generate_conditional_text(immediate, situation, max_length=100):
input_ids = tokenizer.encode(immediate, return_tensors="pt")
attention_mask = torch.ones(input_ids.form, dtype=torch.lengthy, machine=input_ids.machine)
# Encode the situation
condition_ids = tokenizer.encode(situation, add_special_tokens=False, return_tensors="pt")
# Concatenate situation with input_ids
input_ids = torch.cat([condition_ids, input_ids], dim=-1)
attention_mask = torch.cat([torch.ones(condition_ids.shape, dtype=torch.long, device=condition_ids.device), attention_mask], dim=-1)
output = mannequin.generate(input_ids, attention_mask=attention_mask, max_length=max_length, num_return_sequences=1, no_repeat_ngram_size=2, do_sample=True, top_k=50, top_p=0.95, temperature=0.7)
return tokenizer.decode(output[0], skip_special_tokens=True)
# Generate product descriptions with totally different situations
situations = ["Luxury", "Budget-friendly", "Eco-friendly", "High-tech"]
immediate = "Describe a backpack:"
for situation in situations:
description = generate_conditional_text(immediate, situation)
print(f"{situation} backpack description:n{description}n")
This method permits us to generate various artificial knowledge whereas sustaining management over particular attributes, making certain that the generated dataset covers a variety of situations or product varieties.
Purposes of LLM-Generated Artificial Knowledge
Coaching Knowledge Augmentation
One of the highly effective purposes of LLM-generated artificial knowledge is augmenting present coaching datasets. That is significantly helpful in situations the place real-world knowledge is restricted or costly to acquire.
import pandas as pd

from transformers import pipeline
# Load a small real-world dataset
real_data = pd.read_csv("small_product_reviews.csv")
# Break up the info
train_data, test_data = train_test_split(real_data, test_size=0.2, random_state=42)
# Initialize the textual content era pipeline
generator = pipeline("text-generation", mannequin="gpt2-medium")
def augment_dataset(knowledge, num_synthetic_samples):
synthetic_data = []
for _, row in knowledge.iterrows():
immediate = f"Generate a product assessment much like: {row['review']}nNew assessment:"
synthetic_review = generator(immediate, max_length=100, num_return_sequences=1)[0]['generated_text']
synthetic_data.append({'assessment': synthetic_review,'sentiment': row['sentiment'] # Assuming the sentiment is preserved})
if len(synthetic_data) >= num_synthetic_samples:
break
return pd.DataFrame(synthetic_data)
# Generate artificial knowledge
synthetic_train_data = augment_dataset(train_data, num_synthetic_samples=len(train_data))
# Mix actual and artificial knowledge
augmented_train_data = pd.concat([train_data, synthetic_train_data], ignore_index=True)
print(f"Unique coaching knowledge dimension: {len(train_data)}")
print(f"Augmented coaching knowledge dimension: {len(augmented_train_data)}")
