Beginner-Friendly AI Examples

Welcome! This directory contains simple, standalone examples to help you get started with AI and machine learning. Each example is designed to be beginner-friendly with detailed comments and step-by-step explanations.

📚 Examples Overview

Example Description Difficulty Prerequisites
Hello AI World Your first AI program - simple pattern recognition ⭐ Beginner Python basics
Simple Neural Network Build a neural network from scratch ⭐⭐ Beginner+ Python, basic math
Image Classifier Classify images with a pre-trained model ⭐⭐ Beginner+ Python, numpy
Text Sentiment Analyze text sentiment (positive/negative) ⭐⭐ Beginner+ Python

🚀 Getting Started

Prerequisites

Make sure you have Python installed (3.8 or higher recommended). Install required packages:

# For Python scripts
pip install numpy

# For Jupyter notebooks (image classifier)
pip install jupyter numpy pillow tensorflow

Or use the conda environment from the main curriculum:

conda env create --name ai4beg --file ../environment.yml
conda activate ai4beg

Running the Examples

For Python scripts (.py files):

python 01-hello-ai-world.py

For Jupyter notebooks (.ipynb files):

jupyter notebook 03-image-classifier.ipynb

📖 Learning Path

We recommend following the examples in order:

  1. Start with "Hello AI World" - Learn the basics of pattern recognition
  2. Build a Simple Neural Network - Understand how neural networks work
  3. Try the Image Classifier - See AI in action with real images
  4. Analyze Text Sentiment - Explore natural language processing

💡 Tips for Beginners

  • Read the code comments carefully - They explain what each line does
  • Experiment! - Try changing values and see what happens
  • Don't worry about understanding everything - Learning takes time
  • Ask questions - Use the Discussion board
