AI Tutorial - Neural Networks Basics
🧠 Neural Networks - AI Ka Dimag
🌟 Real Life Mein:
Human brain kaise kaam karta hai?
🧠 Neurons (brain cells) - Messages bhejte hain
🔗 Connections - Ek doosre se connected
📝 Learning - Connections strong hote hain practice se
Neural Network = Artificial brain!
🎯 Simple Explanation
Neural Network ek connected network of nodes hai:
- Nodes = Neurons (brain cells)
- Connections = Wires jin se signal jaata hai
- Signal strong/weak = Learning!
Example: Face Recognition
Layers:
- Input Layer - Photo pixels
- Hidden Layers - Features detect kare
- Layer 1: Edges detect
- Layer 2: Nose, eyes detect
- Layer 3: Face shape
- Output Layer - "Kon hai ye?"
Deep Learning: Bohot saare layers = Deep Neural Network = Deep Learning!
Example
# Neural Network structure
input_layer = [1, 2, 3]
hidden_layer = []
output = 0
