Automated Feature Engineering Toolkit Based on Large Language Models

FeatureForge LLM: Automated Feature Engineering with Large Language Models

Overview

FeatureForge LLM is an innovative Python package that leverages large language models (LLMs) to automate and enhance feature engineering processes. By utilizing advanced AI capabilities, this package helps data scientists and machine learning engineers discover, generate, and implement intelligent features across various datasets.

Key Features

• 🤖 AI-Powered Feature Suggestions: Generate feature engineering recommendations using state-of-the-art language models
• 🛠️ Automatic Feature Implementation: Automatically convert feature suggestions into executable Python code
• 🔒 Safe Code Execution: Built-in safety checks to ensure secure feature generation
• 📊 Multi-Provider Support: Compatible with multiple LLM providers like OpenAI and Google Gemini
• 📈 Performance Benchmarking: Analyze feature implementation performance and impact

Installation

pip install featureforge-llm

Quick Start

from featureforge_llm import LLMFeaturePipeline

# Initialize the pipeline with your LLM provider
pipeline = LLMFeaturePipeline(
    llm_api_key="YOUR_API_KEY", 
    provider="gemini",  # or "openai"
    model="gemini-1.5-flash",
    verbose=True
)

# Define your task description and dataset background
task_description = (
    "Predict the disease state of patients with liver cirrhosis. "
    "The objective is to use multi-classification methods to predict "
    "the final disease status of patients."
)

dataset_background = (
    "This dataset contains various physiological indicators "
    "and treatment plans for liver cirrhosis patients."
)

# Get feature suggestions
suggestions = pipeline.ask_for_feature_suggestions(
    df=train_data,
    task_description=task_description,
    target_column="Status",
    dataset_background=dataset_background
)

# Implement all suggested features
result_df = pipeline.implement_all_suggestions(train_data)

Advanced Usage

Custom Feature Request

# Create a custom feature with a natural language description
custom_feature_df = pipeline.custom_feature_request(
    df=train_data, 
    feature_description="Create an interaction feature between patient age and treatment duration"
)

Performance Benchmarking

# Benchmark a specific feature implementation
benchmark_results = pipeline.benchmark_feature_implementation(
    df=train_data, 
    suggestion_id="your_suggestion_id", 
    iterations=5
)

Supported LLM Providers
