🚀 Introduction

Exploratory Data Analysis (EDA) is a critical step in any data science project, allowing analysts to understand data characteristics, identify patterns, and detect anomalies. AI-enhanced EDA tools leverage machine learning and natural language processing to automate and augment this process, making it more efficient and insightful.

This repository provides resources for both beginners and advanced users to harness the power of these AI tools.

🏁 Getting Started

Basic Example

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns

# Load your dataset
df = pd.read_csv('your_dataset.csv')

# Basic pandas EDA
print(df.info())
print(df.describe())

# Missing values check
print(df.isnull().sum())

# Try PyGWalker for interactive visualization
import pygwalker as pyg
walker = pyg.walk(df)  # Opens interactive interface in Jupyter notebook

Using Pandas-AI

from pandasai import PandasAI
from pandasai.llm.openai import OpenAI

# Set up the LLM
llm = OpenAI(api_token="your-openai-api-key")

# Initialize PandasAI with the LLM
pandas_ai = PandasAI(llm)

# Ask questions about your data
response = pandas_ai(df, "What's the correlation between column A and column B?")
print(response)

# Generate a visualization
response = pandas_ai(df, "Create a scatter plot of A vs B colored by C")

Creating Automated Reports

# Using DataPrep
from dataprep.eda import create_report
report = create_report(df, title='My Dataset Analysis')
report.show_browser()

# Using SweetViz
import sweetviz as sv
report = sv.analyze(df, target_feat='target_column')
report.show_html('sweetviz_report.html')

🔍 Advanced Usage

Comprehensive Workflow Example

The file ai_eda_examples.py in this repository demonstrates a comprehensive workflow that combines multiple AI-enhanced EDA tools:

python ai_eda_examples.py

This script allows you to:

• Perform basic EDA with pandas
• Generate automated reports with DataPrep and SweetViz
• Explore data using natural language with Pandas-AI
• Create interactive visualizations with PyGWalker
• Run automated visualization with AutoViz
• Launch interactive analysis with D-Tale

Integration Strategies

For the most effective use of these tools, consider this workflow:

1. Initial Profiling: Use DataPrep or SweetViz for a quick overview
2. Question Formulation: Based on initial findings, form questions
3. Natural Language Exploration: Use Pandas-AI to answer specific questions
4. Interactive Deep Dive: Use PyGWalker or D-Tale for detailed investigation
5. Documentation: Export findings as reports or visualizations

📈 Performance Considerations

• Most tools work well for datasets up to a few hundred thousand rows
• For larger datasets:
  • Sample your data first for initial exploration
  • Use tools with efficient data handling (DataPrep, D-Tale)
  • Consider chunking your analysis by columns or subsets
  • For very large datasets, consider distributed processing frameworks
