Immediate engineering is essential for guiding LLMs to generate high-quality, related artificial information. By fastidiously crafting prompts, we are able to management numerous facets of the generated information, reminiscent of model, content material, and format.
Instance of a extra refined immediate:
immediate = """
Generate an in depth buyer evaluation for a smartphone with the next traits:
- Model: {model}
- Mannequin: {mannequin}
- Key options: {options}
- Score: {score}/5 stars
The evaluation ought to be between 50-100 phrases and embrace each optimistic and damaging facets.
Evaluation:
"""
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 critiques
for model, mannequin, function, score in zip(manufacturers, fashions, options, rankings):
filled_prompt = immediate.format(model=model, mannequin=mannequin, options=function, score=score)
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"Evaluation for {model} {mannequin}:n{synthetic_review}n")
This strategy permits for extra managed and various artificial information era, tailor-made to particular situations or product varieties.
2.2 Few-Shot Studying
Few-shot studying includes offering the LLM with a couple of examples of the specified output format and elegance. This system can considerably enhance the standard and consistency of generated information.
few_shot_prompt = """ Generate a buyer assist dialog between an agent (A) and a buyer (C) a few product difficulty. Comply with this format: C: Hi there, I am having bother with my new headphones. The precise earbud is not working. A: I am sorry to listen to that. Are you able to inform me which mannequin of headphones you've gotten? C: It is the SoundMax Professional 3000. A: Thanks. Have you ever tried resetting the headphones by inserting 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 newest firmware? Now generate a brand new dialog a few totally different product difficulty: C: Hello, I simply acquired 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 real looking artificial buyer assist interactions.
2.3 Conditional Technology
Conditional era permits us to manage particular attributes of the generated information. That is notably 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, system=input_ids.system)
# 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 system permits us to generate various artificial information whereas sustaining management over particular attributes, guaranteeing that the generated dataset covers a variety of situations or product varieties.

real_data = pd.read_csv("small_product_reviews.csv")
# Cut 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(information, num_synthetic_samples):
synthetic_data = []
for _, row in information.iterrows():
immediate = f"Generate a product evaluation just like: {row['review']}nNew evaluation:"
synthetic_review = generator(immediate, max_length=100, num_return_sequences=1)[0]['generated_text']
synthetic_data.append({'evaluation': 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 information
synthetic_train_data = augment_dataset(train_data, num_synthetic_samples=len(train_data))
